Why glued timber?

no crack formation or crooking of glued timber due to the absence of internal stresses

minimum glued timber shrinkage 

ready façade material

perfect heat insulation

optimal microclimate inside rooms

glued timber – environmentally friendly and ensuring lasting quality

Information

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
