KVH® Solid construction wood is a building material developed specifically to meet the high standards of modern wood construction; the product characteristics are defined with accuracy. KVH® is a spruce and technically dried solid product, selected on the basis of resistance and finger-jointed. The KVH® is subjected to additional controls, beyond the general standards of constructions.

The internal quality control and external monitoring are carried out according to the criteria’s agreements on KVH® solid construction wood.




The UNI 11035-3 standard, “Structural wood Classification in sight of the timbers according to the mechanical strength Part 3: River and Trieste Use Joists”, specifies terminology, methods for relevant characteristics determination and the view classification rules of timbers intended for using in load-bearing structures of any size and humidity, according to the mechanical strength and amenable to the definitions of River and Trieste Use.

In accordance with the Technical Standards of Construction “D.m. of January 14, 2008”, structural materials must be subject to a conformity certificate in accordance with community documents. Following the Ntcs provisions, referred to in par. 11.1 and 11.7, a woody assortment may be placed on market by respecting specific certification procedures.



The Gl24h glued laminated wood produced in Austria is used in the Consulting Group House construction system to build the entire bearing structure and roof of the wooden houses.

It is a high-tech material made by the attachment of different resinous wood lamellae, horizontally placed one above the other, and attached by pressing with the help of resin films of gluing, under well-defined temperature and pressure conditions.

The lamellae are obtained by joints on the length using milling means system of selected and different lengths wood pieces.

This structure gives greater homogeneity to the material than solid wood, by improving the strength and rigidity thanks to the reduction of the negative influence of the knots.




Marine plywood can vary in thickness from 3 to 4 millimeters, up to a maximum of 50 millimeters. The wood layers from which it is made are mainly obtained from African mahogany, it is subjected to a gluing treatment using phenolic and melamine glues.

In this regard we point out that since December 2008 sales concerning wood-based panels, finished and semi-finished products with formaldehyde emissions higher than those indicated in the UNI EN 13986 standard has been prohibited in Italy.

The African mahogany essence is characterized by its high humidity resistance, which is the reason why this kind of plywood is increasingly used both in boats and construction sectors. The main difference between marine plywood and normal plywood is, together with the type of gluing that guarantees an enviable resistance to salt and humidity, its kind of essence. Often we improperly tend to speak about marine plywood, even when referring to much less precious essences, such as poplar or birch, divided into layers and assembled with phenolic glues.

The truth about aesthetic and mechanical characteristics is that poplar and birch pay duty against real marine plywood, which is the result of the processing of valuable essences such as mahogany or okumè.



The OSB Type 3 panels (Oriented Strand Board), used by Consulting Group House as a frame to cover the internal part of the external walls, are rigid laminated panels pressed in three directions and made of oriented pine wood strips.

This orientation of the strips provides the hood with strength, rigidity and stability. OSB Type 3 panels can also be used in a wet status thanks to a special surface treatment with resin, which makes them waterproof. OSB3 Type 3 is not a combustible material.



Cork is a non-toxic, biologically pure, unalterable, waterproof, breathable and resistant material.

Blond cork panels have excellent values ​​of thermal insulation and breathability, this material is characterized by the following thermodynamic characteristics: density 150 ÷ ​​160 kg / m2, thermal conductivity coefficient λ = 0.041 W / mK, specific thermal capacity c = 1674 J / kg K, water vapor penetration resistance coefficient μ = 10 ÷ 13 and fire resistance class 2, according to Circ. Internal Min. 14/09/1961, n. 91.

Its characteristics reduce mold and humidity formation index compared to traditional products and guarantee excellent noise reduction. It is an ideal product for anti-trampling insulation of intermediate floors, also thanks to its high compressive strength. Blond cork is also excellent for making natural thermal coats.

The newest insulation technologies synergistically implement these advantages and place these environments at the forefront in terms of reducing heating costs and energy savings. But the main benefit is undoubtedly the CO² emissions decreasing, which is a significant improvement in air quality.

It allows a low environmental impact.



Wood fiber is a plant-based material used as insulator for roofs and walls insulation.

It is produced by processing coniferous wood (pine, fir and larch) and it’s made of scraps and residues from sawmills or forestry. The raw material is therefore free of any chemical treatment and can be considered in unlimited availability.

Panels of different thicknesses, formats and densities are produced from wood fiber, those are an ideal solution for insulating wooden houses as they are breathable materials able to avoid humidity deposits and mold formation.



They are used for lining the internal part of the external and internal walls. The panel is composed of gypsum reinforced with cellulose fibers, which ensures rigidity, great resistance to shocks and they are used as load-bearing panels and bracing elements in the prefabricated wall system.

It withstands loads of up to 50 kg / fixing point, so that suspended elements can be fixed without installing additional reinforcement.

It is an incombustible material that prevents fire spreads and it’s also an excellent sound insulator. Use of gypsum panels reinforced with cellulosic fibers produces both energy savings (thermal conductivity: = 0.21 W / m * K) and manpower reduction, saving time.



It is a natural material and, because of its ecological nature, it is often used also for the eco-sustainable buildings construction.

In addition to ease of assembly, its widespread use also depends on some of its positive properties such as fire and water resistance. It has good insulating, acoustic and thermal skills, making it the suitable material for the counter-walls or partitions construction, both internal walls and walls separating different housing.

Plasterboard sheets are also used to reduce humidity problems, improving the internal microclimate. In addition to all these advantages, the main limit of this construction material must also be indicated, namely the poor mechanical resistance to support elements such as shelves or other furnishings.
