PROJECTS

Construction of glued timber houses has a range of obvious advantages:

- short construction period;

- minimum manual work on the construction site;

- high heat-protective qualities due to the porous structure of timber;

- no shrinkage, due to minimum humidity of glued timber;

- light foundation if compared to a brick house, which provides economy right on the initial stage of construction.

STAGES OF THE WORKS:

Assembling of the house begins with fixation of the timber to the foundation with anchor bolts, and timber here is treated with special wood preservative.                                                                                                 Wooden elements of the house are jointed together with galvanized self-drilling screws which are placed chequerwise in previously drilled holes. The profile of our timber is ‘wedge-like’, so there is no need in additional sealant. For the construction hardness in the places of window and door openings the casing block is placed into the special groove of wall timber. Later a window or door case is fixed to it. The beam and rafter cross section depends on the type of roofing selected by the customer.

WOOD PRESERVATIVES

For the protection of the prospective house from the atmospheric precipitations and microorganisms, ‘Derevianyi Dim’ LLC on the stage of ‘construction kit’ assembly treats the timber with special wood preservatives. This chemical method of wood protection is the most effective as it ensures penetration of protective component into the internal structure of wood. The colorless odourless component with quick drying capacities protects the wood from fungus and insect attacks. The wood preservative treated timber upon the house assembling is covered with wood blue.

After the timber is treated with wood preservative, its butt ends are treated with a special mixture that makes the timber deformation-resistant due to prevention of wet absorption on the butt cutting and in V-junction area of wooden constructions used for outside works, and forms the colorless elastic water-repellent film on the surface.

All treating mixtures have the European quality certificate.

How to choose glued timber of true quality?

A few hints for the Customer:

1. The lamellas, of which the timber is formed, have to be jointed from the dimension parts 30-80 cm long. This would guarantee absence of longitudinal cracks and ungluing between the lamellas. The timber glued from the solid boards, besides the mentioned cracks will have light knots and pitch pockets, with a probability to be crooked.

2. The length of timber should be 12 m – this guarantees less waste in the cutting-out and a more reliable structure, due to the lack of the butt-joints.

3. Consider the processing quality of the facial surfaces, longitudinal profile and precision of crowning cups incision.

4. There some moments you would not able to check – the glue quality, and compliance with the gluing technology. In this case the best decision is to have a look on the ready houses that have been standing for not less than 6 years – this will help you to make a choice.

5. The company, having regular orders, should have their own design bureau (or at least an architect and designer). The firms that have 1-2 orders per year cannot afford this.

Comparative characteristics of the wall from glued beams and brick walls.

Thermal conductivity for ceramic brick is 0.7 W / (mK).

Thermal conductivity for laminated veneer lumber is 0.12 W / (mK).

Thus, resistance to heat the walls of laminated veneer lumber thickness of 18 cm, is:0.18 m / 0.12 W / mK = 1.5 sq.m * K / W. Therefore, to provide the same resistance to heat as wood, brick wall must be thickness: 1.5 sq.m * K / W x 0.7 W / mK = 1.05m
