Wood Construction enable substantial energy savings

The ideal temperature at low cost. It is the profile of the house that we all want, a goal more attainable today than yesterday. Yet the modern building techniques alone are not enough and need to make use of natural materials for a healthy return to the origins that combines energy efficiency. A goal achieved by the use of wood in construction.

The insulation: what is it

The thermal insulation of buildings is essential to ensure optimum temperatures in both summer and winter. Recent estimates show that about 70% of the energy costs incurred by a family are intended for heating of the domestic environment. It is often a lot of the energy required to disperse through the building envelope. Good insulation, compared with a limited increase in construction costs, yields a saving of costs which is between 80 and 90% on heating costs and refrigerated. 

Because wood in green building

Much is investing in isolation from external environments through materials still little used in traditional construction systems. Cork slabs, of wool or wood fiber, wool, coir, wool, cellulose, sheep wool, jute felt: these are the most popular materials in sustainable building.

Another system which ensures a low energy loss is the total insulation of buildings. In this perspective, all the structures of the building are made as if they were carriers, or with the same materials and physical characteristics, identical for both the internal walls that for those carriers. A solution easily available with the use of the resource wood, variously be used in all parts of a building.

 

The wood "breathes"

It is still the wood to ensure ideal temperatures. It is a material "hot" by nature, with a density such as to ensure a dispersion of heat limited. The wooden houses are cool in summer and warm in winter and can achieve an energy saving of approximately 35/40% compared to traditional brick-concrete buildings. Furthermore, wood has a thermal transmittance estimated 12-fold lower than 1500 times less concrete and aluminum. For this reason it is used more and more often in the fire protection of steel structures.

At the same thickness the thermal resistance of the wood is six times higher than that of the clay. Quality that does not forget the ability to acoustically isolate the premises and to prevent moisture buildup. The value of the permeability is, in fact, essential to ensure the right comfort. Why "isolate" does not mean "waterproof" an environment.
