In the choice of doors and windows for your home, it is good to choose a quality product especially for the purpose of good thermal insulation; this choice also allows us to take advantage of the 65% tax deductions. The aspect of sound insulation should also not be underestimated, a fundamental element to ensure adequate comfort in the home environment. The commercial offer is such that it can satisfy any need in the choice of materials, finishes and models.
Insulating doors and windows in wood and aluminum
Mixed wood-aluminum windows are very popular: they are elegant on the inside thanks to the wood cladding and resistant to atmospheric agents on the outside thanks to the aluminum cladding.
Insulating windows, low-emissivity glasses
The low-emissivity glasses with a chamber filled with Argon gas, are covered with a film that improves their thermal performance without limiting their light transmission capacity.
To further improve the performance of this type of glass, the warm edge channel in stainless steel and polypropylene is used, instead of aluminum, which further lowers the thermal transmittance value and therefore the insulating power of the frame. Added to this is also the reduction of condensation along the edges and, therefore, of mold and discolouration.
Insulating doors and windows, selective glasses
To increase the thermal performance in the hot season, you can opt for the choice of a selective glass, which combines the advantages of the low emissivity one with a reduced solar factor: it creates a barrier to the entry of heat from the outside, but maintains a transmission of light equal to 71%.
Window requirements for tax deductions
65% deduction for windows: window requirements
To access the tax deduction it is important to respect a certain limit value of thermal transmittance of the window. Thermal transmittance indicates the amount of heat that passes through an element with a surface area of 1 square meters in the unit of time in the presence of a temperature difference of 1 ° C between the inside and the outside. From this it is clear that a low value of transmittance corresponds to little heat transmitted, therefore a window is all the more efficient the lower its transmittance value is.
It is also important that the windows to be replaced delimit the heated volume and therefore face the external environment or unheated rooms. Therefore, there is no right to the 65% deduction for windows present in rooms without a heating system, such as basements or condominium stairwells.
