Wooden frame house: the 8 advantages of insulation!

The wooden frame house is a house very well insulated from heat, cold or outside noise. These performances are the result of a clever construction method which also offers great architectural freedom to the resident. We take stock of the 8 major advantages of insulation.

 

High-performance insulation and simplified installation

Today, thewood frame is the most widespread wood construction system in France. The structure of the exterior walls on which the frame and roof rest is made up of wooden uprights spaced closely apart (approximately 60 cm). There prefabrication boxes made up of uprights, lower and upper rails, and wooden panels which close and ensure the stability of the whole (bracing) offers more efficiency and speed on site. Once assembled, the boxes constitute the main structure of the exterior walls in which the doors and windows are incorporated. A first layer ofthermal insulation fits into the boxes, between the uprights. A second layer of insulation, or even a third, reinforce the thermal performance from the whole.

Why is a wooden frame house better insulated from the cold?

In general, insulation thicknesses are much more important in wooden house. THE winter comfort is thus exceptional for a energy bill scaled down. The wooden house very easily reaches the standards required by the RE2020. They easily exceed expectations low energy houses and easily approach those of the passive house. Result: homes where you barely need to turn on the heating, without feeling uncomfortable, even in the middle of winter. There wood frame house is thus the preferred constructive process for those who are cold!

Maisons Bois Sic: double insulation!

At the south west builder Sic houses, wooden houses are doubly well insulated. A traditional brick or concrete house is generally insulated from the inside. More rarely from the outside. While these two ways of doing things have their advantages, that is not how the wood frame house. THE'insulating is in fact placed between the amounts, what we call distributed insulation. To ensure additional performance, particularly phonic, the wooden house Sic also receives thermal insulation from the inside and sometimes from the outside. The performances are only increased tenfold. Thanks to these two insulations the house is well protected and the thermal bridges are thus doubly avoided.

the interior of a wooden frame house before insulation in the Landes.
Once this wooden frame house has been sealed off from the water, a first insulation will take place between the uprights of the exterior walls. A second insulation from the inside will reinforce the whole.

The wooden house: no thermal bridges

Un thermal bridge, this is not visible upon delivery of a new house, but what damage in use!!!! These are the small places where the insulation was not placed correctly. This results in a cold spot, often located at the junction of the walls: junction of walls and ceilings, junction of walls and floors, etc. The problem is that the hot air inside meets the cold outside. This accelerates heat transfer between the inside of the house and the outside. Not only the thermal bridge considerably reduces the performance promised by very strong insulation, but worse still, it creates condensation points which can damage materials in the long term. A disadvantage that is more difficult to encounter in a wooden house because the wooden structure itself is insulating. There double insulation implemented by the builder Sic Houses provides additional security.

Construction of a wooden frame house: saving m2 on insulation

This is one of the great advantages of wooden house. The insulation is in fact wedged into thewood frame. Insulation thicknesses are generally greater without loss of space. We can thus easily gain living space by opting for a wood frame house. Perfect for small homes where small lots where the slightest square meter is pretty good to take.

Does a wooden frame house insulate from outside noise?

The proximity of a main road or a busy living space should not slow down the construction of a timber frame house. The latter is perfectly designed to offer a haven of peace to its occupants, even on very noisy terrain. The constructive principle of the wooden house guarantees thesoundproofing since the insulation is placed between an interior facing and an exterior facing. This process creates what is called a “ mass-spring-mass » , a configuration that traps sounds and offers perfect soundproofing in a minimum thickness. The second, or even the third, layer of insulation implemented by Maisons Sic makes it possible to further improve these sound performances.

airtightness of the wooden frame house in the Gers
On the outside of this wooden frame house, the airtightness is supplemented by a rain barrier membrane which provides additional security for watertightness, but allows water vapor to pass through for walls which breathe!

Wooden frame houses: perfect airtightness

The high performance of the wooden house are also linked to a perfect airtightness. So that the house ensures good thermal performance, it is necessary to prevent leaks and parasitic air inlets. The barrier is generally provided by a specific par/air film and a plaster facing inside the house, and by the bracing panel and possibly by another par/air film on the outside.
At the end of the project, an infiltrometry test ensures that the level of air permeability of the building envelope corresponds to the requirements defined by the thermal regulations 2020 say RE2020.

Wooden house: a well-insulated house that breathes

Like all constructions, the wood frame house must eliminate the water vapor produced naturally by its occupants and their activities (drying laundry, cooking, etc.). This is, first of all, the essential role of ventilation, but this does not prevent the transfer of water vapor through the walls. The perfectly wooden house airtight, is also capable of evacuating humidity that can infiltrate its walls. The screens placed in front of the insulation are both airtight and offer a high water vapor permeability. A feat that allows real longevity for the Wooden House.

Conclusion

The design of the wooden frame walls thus offers good performance which complements the performance of the roof. The masonry house also has advantages. This is why Maisons Sic also offers mixed houses which combine the advantages of the wooden frame house and those of the brick house.
