Windows are one of the most vulnerable elements in buildings’ surroundings. In winter, heat losses can represent 30% of heating needs.
HOW TO REDUCE YOUR CONSUMPTION ASSOCIATED WITH COMFORT?
The efficient windows, due to their characteristics, contribute to the increase of the thermal and acoustic insulation of the buildings, allowing to reduce the energy consumption associated with the air conditioning of the spaces in values in the order of 50%.
The installation of efficient windows allows for greater thermal comfort, reduction of air and water infiltrations and consequent risk of inherent pathologies, as well as saving on the energy bill. These windows can have wooden, PVC or aluminum frames with thermal cut (thermal break) or a combination of them. For glazing, you should consider, at least, a double glass, and you can choose for the gas that separates the two layers of glass, air or a noble gas, for example, argon.
You should consult with the supplier in order to obtain the best options for your home, considering, in addition to the energy performance, other factors, such as the orientation of the windows, climate, construction limitations, durability and other factors to be taken into account.
