Glued laminated timber is a sawn timber consisting of several wooden panels glued together. Made independently, it is more profitable than the factory one, not only financially. Self-made sawn timber can be of any size, section, or higher quality.
Regarding the last parameter, there are many complaints from buyers of factory glued beams. In order to save money for gluing, manufacturers often use poor quality wood, which determines low strength characteristics finished product.
What is needed for self-manufacturing of laminated veneer lumber?
The boards from which the timber is glued are called lamellas. They should be even, without signs of rot, cracks, well dried, with minimum amount knots. The basic rule for gluing the timber is as follows: the lamellas should be laid so that their annual rings are in different directions.
In addition to wood, you should stock up on glue. Optimal use of PUR-Glue 510 FiberBond. This composition is designed for gluing wood, therefore, it will provide a high bond strength of the boards. But you can take any other designed for woodworking. From the tools you will need clamps, a hacksaw, a solvent for degreasing the material, a fire retardant compound, medium-grain sandpaper.
How to make glued laminated timber with your own hands?
Glued laminated timber can be made in three ways: by joining three lamellas; two lamellas connected by the letter Z; glued from lamellas with inserts. The first one is most often used, since it is much simpler and faster.
First, the boards are selected for gluing the timber, then they are stacked one on top of the other so that the annual rings are directed in opposite directions. Then the boards should be signed with a simple pencil or marker. This precaution will allow you not to confuse the order of their laying.
Then, the center board is processed on both sides sandpaper, which will give it a roughness. It will increase the adhesion of the adhesive to the wood. Side lamellas are processed only on one side: the one that will be inside the timber.
Further, dedusting and degreasing of these surfaces is carried out using a solvent and a fire-retardant composition. These liquids are alternately applied to the boards: first, the solvent is applied to the sanded surfaces, and after it dries, a protective impregnation is applied. It covers all sides of the lumber, including the ends.
Then glue is applied to the lamellas with a layer of 1-2 mm. The boards are stacked on top of each other so that their ends form a single plane on each side of the timber. After that, the lamellas are fastened with clamps, which should be 40-45 cm apart from each other. The drying time of the glue is indicated in the instructions for the composition, but it usually does not exceed 1-2 days.
I'll start the article with the question - why do you need to make glued laminated timber with your own hands? Often, but not always, it is needed in small quantities to renovate furniture, for example. In our case, we did a small renovation of the sauna. It was necessary to install a small hinged partition in the shower room to hide the person taking the shower from prying eyes. Why did we become interested in the production of laminated veneer lumber on our own, because the customer still had linden blocks from the construction of the sauna and we just applied it. We also made strong shelves from the remnants of laminated veneer lumber.
We make glued laminated timber with our own hands
By the way, purchasing glued laminated timber in small volumes or of the required length is quite problematic.
Why do glued laminated timber if you can use one-piece?
1. It is stronger than the usual solid one.
2. Glued laminated timber practically does not perceive changes in humidity and temperature as solid.
The modern glue that we will use for manufacturing is of very high quality, so the seam is even stronger than the wood itself. You can see this for yourself when, following our example, you start manufacturing. For wood glue, we will use PUR-Glue 510 FiberBond, this glue is specially designed for the production of laminated veneer lumber and has a high bond strength.
To connect the pieces together, we chose a keyway connection. In principle, other joining methods can be used for home production. Before starting the assembly, make sure that the timber is correctly positioned between each other. It is important to position the annual rings of the wood in a different direction from the adjacent piece (see Fig. 1). This will make glued laminated timber (more details about it here http://grandstroi.ru/services) resistant to warpage from changes in humidity and temperature.
For production, you need a small set of tools.
A jigsaw or a hacksaw, a set of clamps for fixing, a milling machine for making keyways, a tape measure and a set of brushes for painting the finished product.
As we said, we will make glued beams from the remains of linden beams. This material is quite dry as it was stored in a well-ventilated shed under the roof.
Then we cut the blanks into pieces 1000 mm long, this is the height we will have the door in the shower room. We select three bars and place them correctly according to Fig. 1. Further, after gouging and jointing, we make grooves with a cutter on the middle bar on both sides, and on the extreme ones on one side, which will be glued. After that, you need to make the key itself, clearly according to the size of the groove. It is better to assemble the structure without glue before gluing the blanks together, to make sure that everything turns out to be in size.
It is very important to properly prepare the bonding surface. To do this, the surface must be cleaned and degreased, for degreasing we use solvent 647 or 646 which will be at hand. So, we process the glued surface of the bars with fine sandpaper, clean the dust with a brush or rag, and degrease it with a solvent. The wood is now ready for bonding.
We have already chosen the glue, so we are only required to do everything in strict accordance with the instructions for use of the glue. After gluing, you need to fix the bars with our set of clamps.
On this DIY glued laminated timber not finished, since the product must dry out, for this we remove it in the shade, it is better to put it under a canopy to ensure an unobstructed air flow. How much to dry the timber can be found there in the instructions for using the glue.
Glued laminated timber refers to modern species lumber. During construction wooden houses it acts as an alternative to the rounded log and. A complex production technology leads to an increase in the cost of the material, but in return, buyers receive highest quality and excellent performance characteristics .
Glued laminated timber is combined construction material ... It is based on sawn boards, which are glued together using adhesives along special technology... For manufacturing, lamellas are used that are free from defects and knots.
Glued laminated timber is profiled - this allows you to create desired cutting geometry for fast and efficient erection of structures.
Also, it is devoid of the disadvantages inherent in natural wood, - flammability, tendency to deformation and significant shrinkage. But thanks to modern approach and use adhesive mixtures material acquires additional beneficial features – high strength, thermal conductivity and dimensional stability.
A house made of this material turns out to be durable, warm, cozy, with a characteristic microclimate. natural wood... And it is possible to build it in the shortest possible time.
Which is better - ordinary timber or glued?
When making a choice between the traditional profiled timber and the glue type of sawn timber, one should focus on the positive properties of the former.
The advantages of a profiled bar include the fact that it is solid array wood... It is a completely natural building material with high environmental friendliness. It can be treated with solutions that prevent decay and fire, but they do not emit harmful vapors and odors.
Another plus of the profiled material is low cost in comparison with the glued look. The latter will cost about 30% more.
In addition, there is a natural air exchange in the classic timber, which creates a special microclimate in the dwelling.
But profiled is inferior to glued on variability of sizes, levels of moisture and shrinkage, the likelihood of deformations and partial loss of properties during operation. He often requires finishing works to improve aesthetics and periodic caulking of emerging cracks.
Classification
In construction, several types of material are used, depending on the intended purpose and profile configuration.
Types of material by appointment:
- Window and door... It is made from at least 4 lamellas, it is used in the areas of installation of window and door openings.
- Wall. The number of lamellas reaches 2-3, it is used to build walls in one-story houses and buildings with an attic.
- Reference... View from the greatest bearing capacity... It is used to construct building frames, floor beams and load-bearing supports.
The parameters of the wall beam most demanded for construction are 100-160 * 180 and 180-270 * 260 mm.
The wall beam can be made with or without an insulating layer.
Types by profile type:
- comb- equipped with fine teeth cut on the sides of the product;
- Finnish profile- forms a thorn-groove connection, its surface is almost flat;
- german profile- has from 4 to 8 connecting slots, forms the strongest module.
House kits from the manufacturer
A house set from a bar is a building set consisting of several hundred elements intended for the construction of a building. Essentially it is finished houses disassembled.
Important! Installation of a house kit made of laminated veneer lumber is carried out only on a well-established foundation.
All parts of the kit have strictly verified dimensions, made in accordance with the architectural design. The elements are fitted to each other, which greatly simplifies and speeds up construction.
The assembly includes:
- cap wreath;
- interfloor floors;
- base for the roof;
- rafter system with crate;
- pillars, logs, beams;
- external and internal walls;
- finishing and rough floor.
The set includes assembly documentation with detailed diagram assemblies... Each item must be numbered and packaged.
Glued laminated timber production
Manufacturing technologies were developed in Finland about 30 years ago.
Nowadays modern glued sawn timber is produced serially all over the world.
The resulting product is processed and completely ready for use.
Raw materials for manufacturing
Manufacturers prefer to use conifers trees due to their availability and low cost. The trunks are in operation pine, spruce and larch, wood is used abroad cedar and fir... Due to the high cost of raw materials, oak and ash beams can only be made to order.
In the production of multilayer timber, they often combine natural materials... For the outer layers, spruce and pine are used - the structure of their wood is more uniform. Larch and cedar are used for internal inserts - they are characterized by high strength.
Raw materials from northern timber are most valued - it has upper class strength.
Types of glue
For the manufacture of glued beams, several types of glue are used. They differ in classes of water resistance, operation and environmental safety.
- Melamine. Transparent glue, used in Russian and European production for the construction of large-span structures.
- Resorcinol... A dark composition with increased moisture resistance, they are glued to the outer parts of the timber for operation in conditions high humidity... This type of material is used by US manufacturers in shipbuilding, bridge construction and open structures.
- EPI system... Transparent adhesive composition, used in low-rise construction in Japan and Russia.
- Polyurethane... Has a transparent structure, quickly hardens. Suitable for gluing window and door beams.
Quality standards
The production of laminated veneer lumber does not require the preparation of a license. But the products must comply with quality standards, confirmed by appropriate certificates.
State standards for glued laminated timber:
- GOST 20850-84 “Glued wooden structures. General technical conditions ”;
- GOST 16588-91 “Sawmill and wooden parts... Moisture Determination Methods ”;
- GOST 19414-90 “Glued solid wood. General requirements";
- GOST 25884-83 “Glued wooden structures. Method for determining the strength of adhesive joints during layer-by-layer spalling ”;
- GOST 15613.4-78 “Glued solid wood. Methods for determining the ultimate strength of serrated adhesive joints in static bending ”.
Manufacturing technology
- Preparation of raw materials... Undried and uncut boards are sorted, sawn into workpieces according to the specified parameters, cleaned of bark and sent to the chambers for drying. The final moisture content of the board should not exceed 8-12%.
- Defect removal and calibration... Each board is processed on four-sided machines. This allows you to eliminate the remnants of wane, knots, cracks and other defects.
- Grinding... Finishing of the lamellas is carried out to ensure the geometric accuracy and tightness of the blanks.
- Gluing... The glue applicator applies the adhesive to the wide side of the workpiece in an even layer. Then the lamellas are pressed into a solid bar under a pressure of 15 kg / m2 for 30 minutes.
- Profiling... On the sides of the timber, cuts are made in the form of spikes, ridges, grooves in accordance with the planned configuration.
- Treatment protective compounds . Finished goods impregnated with mixtures that prevent burning and rotting of laminated veneer lumber.
Finished products are quality tested and packaged for shipment or storage.
Why do it yourself?
If you have the necessary tools, you can independently make a glued-type beam. This allows you to get material of non-standard dimensions, which are not found on sale.
DIY will help adjust the layers of the timber for strength, flexibility, length, width, type of surface... It can be used for finishing works, furniture restoration and other small jobs where the purchase of large quantities of laminated veneer lumber is impractical.
note
Suitable for manufacturing ordinary boards or slats from a construction supermarket.
For a more thorough and accurate processing, use milling machines and grinders , but at home you can do it a hacksaw and a plane... The surfaces to be glued are especially carefully treated - they are sanded, dust removed and degreased.
Gluing is carried out using ready-made glue, which can be bought in retail outlets... The instructions for applying and drying the adhesive must be strictly followed.
To fix and compress the glued parts, use clamps... After drying, the finished timber is finally planed and polished.
What is Finnish laminated veneer lumber?
Finnish profile types include slices from complex configuration and insulation... The lower edge of such a bar is equipped with connecting spikes, and on the upper edge there are grooves corresponding to the spikes in size. The stepped groove located between the pins is deeper in the middle and shallower along the edges.
Along the edges of the groove place the sealing material, and in the center is placed thermal insulation synthetic tape... The groove is covered with beveled edges on the sides top bar... This design allows you to achieve high level thermal insulation, to avoid moisture ingress and blowing of the structure.
This type of insulation is laborious and expensive. Simplified and budget options suggest sealing only in the center or only on the sides. This also allows you to achieve good performance impermeability.
Advantages and disadvantages of the material
The demand for laminated veneer lumber is growing every day. This is due to the numerous positive properties and virtues material:
- The minimum percentage of shrinkage, which allows you not to wait for shrinkage at home, but immediately put it into operation.
- Excellent thermal insulation properties, often not inferior.
- Does not require finishing - the surface of the timber is even and smooth, has no cracks or defects.
- The timber is not susceptible to burning, decay, wormholes and fungal infections.
- Maintains geometric proportions, does not deform and does not change shape.
- Glued laminated timber is easy to install, which significantly reduces the construction process.
- Subject to proper installation, high moisture resistance and resistance to wind penetration are ensured.
- It has no length restrictions, and the thickness of the product can include up to ten lamellas.
- The low weight of the products does not require the use of special construction equipment.
disadvantages glued laminated timber:
- The high cost of lumber compared to rounded logs and profiled beams.
- The need to maintain a certain level of humidity in the dwelling in the absence of temperature extremes.
- Low air permeability of structures.
- The need for additional thermal insulation during construction.
Some manufacturers use low quality synthetic compounds for gluing, which significantly reduces the environmental friendliness of timber products.

The essential advantages of laminated veneer lumber make it popular and effective building material for the construction of durable buildings. The high price is paid off by the beautiful appearance of the building from the outside, by a comfortable and cozy atmosphere inside.
Construction multilayer material is made from a pre-prepared solid wood. Used as raw materials edged boards made from coniferous trees.
Modern technology for the production of laminated veneer lumber includes the preparation, manufacture and processing of finished material.
Production stages
On initial stage wood is being prepared. The logs are dismissed into boards in accordance with the required dimensions and placed in drying chambers... Drying takes place until the moisture level of the wood is set at 10%.
The deviation that is allowed in the direction of increasing the parameter or decreasing does not exceed 2%. After drying, the building material is sent to the workshop to check the quality of the material. The specialist checks the moisture level using a moisture meter.
Examination
If the obtained values do not match valid parameters, then the blanks are returned to the preparatory shop. Depending on whether the humidity indicator is exceeded or lowered, the boards are sent for drying or conditioning, respectively.
The material that has passed the moisture control is checked for defects. All discovered deficiencies are eliminated and the boards are sewn into a mini-tenon. At this stage of the glued laminated timber production process, lamellas are obtained, which are the main raw materials. Further, the lamellas and boards are planed.
Gluing
At the next stage, gluing machines are included in the production. With their help, glue is applied to dried, checked and planed lamellas and boards. The number of lamellas to be glued varies from 2 to 6 pieces. Depending on the type of product received, the width and height may be different.
For non-profiled timber, a width of up to 1.3 m is allowed, and the height is determined by the size of the board. To obtain a profiled product, a width of 240 mm and a height of 180 mm are used. The glue that is used for the production of glued profiled timber is selected based on strict safety requirements.
The material must be environmentally friendly, the composition must not contain formaldehyde, heavy metals, toxic substances, toluene and others hazardous to human health or the environment components. The glue is certified and must comply with a special standard that allows it to be used in the manufacture of products in contact with food.
Some factories use safe polymer adhesive based on isocyanate emulsion. On glue-pouring machines, glue is applied to the surface of the material in the form of thin, uninterrupted lines. This method of application excludes the appearance of streaks on the edges of the workpiece at the time of pressing. Boards and lamellas are assembled in a package and sent to the press shop by transport equipment.
A horizontal mechanical press creates high pressure for blanks. In this state, they are kept until the glue is completely dry. At this stage, it became clear how glued laminated timber is made, the material only needs to be carefully processed.
Mechanical restoration
After gluing, the blanks are sent to the machining workshop, where the craftsmen give the products a presentation.
At this stage, different woodworking equipment is used. Depending on the structural need, bowls are cut, profiling, trimming on a special machine, and width gouging are performed.
Protection
The technological process for the production of timber is completed by the treatment with an antiseptic and a special composition to increase the fire resistance. The work is done manually by employees. The composition is applied to the surface of the products using paint brush... To obtain high strength and moisture resistance, glued laminated timber after chemical treatment is aged for 24 hours. How and from what glued beams are made , sorted it out.
At enterprises using this technology, two types of timber are manufactured: enclosing and supporting. The load-bearing building material is used as floors, rafters, columns. During manufacturing, products are reinforced with metal or plastic fittings. It is glued into the middle of the timber. No reinforcement is used for the production of enclosing structures.
Compared with round log, glued laminated timber has the best thermal insulation performance, allows you to get good density fit, providing the structure with high airtightness.
Thanks to the profiled grooves and ridges, the products are rigidly fixed in rows. The glued laminated timber construction looks monolithic and does not require finishing. The building practically does not shrink and does not change its original shape over time. This material has become very popular in low-rise construction.
In wooden construction, logs, beams, boards are used (in frame construction), but wood has several rather serious natural drawbacks, which manufacturers of lumber for the construction of houses are trying to level today.
One of the most high-tech materials for construction country house permanent residence is profiled. We offer an overview of how to build a house from laminated veneer lumber, with a description of all the stages of assembly.
Advantages and disadvantages of a laminated veneer lumber house
A house made of laminated veneer lumber has a number of advantages that are inherent only in buildings made of this material.
Advantages of laminated veneer lumber houses
- low thermal conductivity. Private house built of laminated veneer lumber does not need insulation;
- the ability to implement a project of any complexity. Due to the geometry of the bar, you can make long walls without splicing. In addition, there is an opportunity to purchase bent laminated veneer lumber. At the same time, using glued laminated timber in construction, it becomes possible to assemble walls different thickness, which is a source of savings during construction;
- there is no need to seal the walls. The tightness of the timber and the minimum cracking allows you to abandon caulking and sealing joints;
- antiseptic treatment. Manufacturing technology of laminated veneer lumber provides for the unfolding of the lumber on the boards and their subsequent gluing. This makes it possible to cut out knots and other defects, as well as dry the board to the desired moisture content. The glue that connects the lamellas acts as an antiseptic. In addition, glued laminated timber is processed with fire retardants;
- environmental friendliness. Adhesives and the wood used is certified for compliance with standards and safety;
- biological inertness;
- high speed of construction, which reduces the construction / commissioning time and allows you to quickly move into the house;
- minimal shrinkage, which makes it possible to start finishing immediately after the end of construction;
- aesthetic appearance... Glued laminated timber does not crack like a log or natural timber. This reduces the requirements for external finishing;
- strength and long service life.
Cons of houses made of laminated veneer lumber
There are much fewer disadvantages, but they are:
- higher, chamber drying, timber cost;
- the need for constant wood care (a feature of all wooden houses) in order to reduce the rate of aging and discoloration.
As you can see, there are more attractive sides than negative ones, which is why construction log houses popular in Europe.
Stages of building a house from laminated veneer lumber
As already mentioned, glued laminated timber is a relatively easy material to work with, and step-by-step instruction, describing in detail each stage, will eliminate errors and outline a plan for starting the construction of a house with your own hands or attracting a contractor.
| Stage No. | Name | Content |
|---|---|---|
| 1. | Project development | - an individual or typical project. |
| 2. | Pouring the foundation | - calculation of the type of foundation depending on the characteristics of the soil, terrain, level groundwater, project, etc. factors; - arrangement of the pit; - arrangement of reinforced formwork; - pouring concrete and gaining strength. |
| 3. | Laying the first crown | - waterproofing; - the first row of a bar. |
| 4. | Installation lag | - device of the subfloor above the plinth; - installation of the subfloor above the basement; |
| 5. | Box construction | - laying the rest of the rows; - device interior partitions; - installation of interfloor ceilings. |
| 6. | Roofing | - mounting rafter system; - mounting roofing cake(insulation and decoration). |
| 7. | Installation of individual elements | - installation of vertical structural elements (pillars, columns, supports); - filling of openings (window and door frames); - installation of stairs. |
| 8. | Interior decoration | - communications; - decorative finishing |
| 9. | Outdoor decoration | - point sealing; - wood protection. |
Proper preparation for assembly at home and a clear sequence of work execution guarantee a high-quality result.
Stage 1 - Project development
Glued laminated timber house project - necessary condition to start construction. There are four ways to get a project:
- download finished project (free on the Internet) and perform work on it. But, it is worth remembering that the network contains projects that are developed for specific users and operating conditions. Just copying the finished project, you may encounter a discrepancy between the type of foundation and the type of soil, with an insufficient size of the house, difficulties with connecting communications, etc.;
- download the finished project and change "for yourself"... The most popular option. However, it requires making changes, and for this you need to have certain knowledge and skills in working with computer programs in this area (ArchiCAD, AutoCAD);
- order development in construction company ... Typically, they offer many options to choose from and take care of everything related to making changes and obtaining permits. This option is not suitable for everyone who plans to build a house from laminated veneer lumber with their own hands, because requires additional costs;
- to order individual project ... Note that the cost of the project can reach 25-30% of the total construction estimate. Material prepared for the site www.site
How to redo a project at home?
Many owners are taken for independent revision of ready-made standard projects(adaptation to certain operating conditions). To avoid mistakes, you need to take into account:
| № | Factor | Description |
|---|---|---|
| 1. | Purpose of the building | - dacha; - house for seasonal residence; - a house of permanent residence. |
| 2. | Material parameters | - moisture indicators: for laminated veneer lumber is 12-15%; - geometry: the appearance of the timber, affects the appearance of the assembly; - section; - profile view. |
| 3. | Building area | - number of rooms; - the area of the rooms; - the configuration of the house and the layout of the rooms; - number of floors; - the presence of a ladder and its parameters; - specific needs of residents; |
| 4. | Location of the house | - the ability to connect to central communications; - the influence of other objects (well, reservoir, septic tank, access roads); - the appearance of the site (relief, perennial plantings, trees); - soil features; - remoteness from the boundaries of the site. |
As a result of the design, a finished project is created, according to which permits will be obtained.
Note that construction with the subsequent legalization of the object is a rather complicated and costly task, so it is better to obtain documents for the construction of a house before it starts.
To approve a house project, you must provide:
- foundation drawing... This document contains data from engineering and geodetic surveys (soil, relief, composition, groundwater level, depth of soil freezing) and data on the foundation (type, depth, material used);
- floor plan... It indicates: the number, size and place of installation of windows, doors, walkways, partitions, communications, fireplace, stairs. Each item contains a description and dimensions;
- scattering... A document containing data on the number and section of the timber that will be used for the construction of each of the walls. Having a scattering, it is easier to make the calculation of laminated veneer lumber for building a house.
- specification of elements with indication of dimensions... It is convenient to compose such a document using a computer program;
- roof data with detailed description roofing cake(material, its parameters, type of insulation, films, gaps, type roofing material, heating pipes, the presence of windows, etc.).
- project visualization.
What kind of laminated veneer lumber is better to build a house from?
When developing a project, you need to take into account the parameters of the bar itself.
- 100x100 mm - buildings not intended for permanent residence, gazebos;
- 150x150 mm - at home (with mandatory insulation), baths;
- 200x200 mm - houses of permanent residence.
The section of glued laminated timber on request can be increased up to 360 mm, and the length of the timber can be up to 18 meters (limited by the possibility of transportation).
Heat transfer resistance for a house is calculated based on the recommendations of SNiP II-3-79.
What kind of laminated veneer lumber profile to choose for the house?
- comb or German profile allows you to provide a very tight joint of the timber. Such a joint does not require the use of heat-insulating material, however, it is rather difficult to fold the timber clearly without work experience;
- Finnish profile or Scandinavian makes it possible to lay thin thermal insulation material between the crowns. Thanks to the configuration of the profile, it is easier to fold it for beginners with no experience in construction.
House set made of laminated veneer lumber
Another factor that will make your home faster and of better quality is the use of a home kit.
Domokomplekt- this is ready-made kit glued laminated timber for building a house. All beams are marked, the length set by the project and the landing bowl. The assembly is performed according to the instructions (like a constructor).
The set of the house kit includes: beams of crowns, beams for floors, material for arranging a rafter system, logs of a subfloor, details according to the project (columns, supports, beams for a wall, etc.). May contain elements on request fine finishing: finishing floor boards, terrace board, lining for the ceiling, etc.
The use of a house kit allows you to reduce the work on the arrangement of seats.
You can order a house kit from the manufacturer of laminated veneer lumber. It should be borne in mind that the kit will cost 20-25% more than the molded timber. But, with complex project, this is the best option.
As a rule, it is the manufacturer who assembles the house from laminated veneer lumber, because offers competitive pricing. Those. It is possible to buy a house kit made of laminated veneer lumber from the manufacturer separately, but the price will be an order of magnitude higher than the one that the plant provides for the turnkey service.
Comparison of construction from molded timber and a house kit from glued laminated timber for self assembly in the table:
Stage 2 - Pouring the foundation for a house from a bar
Peculiarity wood construction in the fact that the work is carried out using a relatively light material (than, for example, brick), which reduces the requirements for the base. The foundation is poured in accordance with project documentation, and work is suspended for the duration of strength gain.
