From January 2021, new rules on carpentry come into force. The most significant changes concern the energy efficiency of buildings. The new rules also apply to window joinery. Who will be in effect and what will change?
The main objective of the new rules is to focus on the energy efficiency of homes.
Who are the new building regulations?
The law, which entered into force at the beginning of the new year, sets out the requirements for the heat transfer coefficient,which for vertical windows will be reduced from 1.1 W/m?K to 0.9 W/m?K.
Through the windows, a lot of heat escapes from our houses, so they are exacerbated by m. Others. provisions on their insulation. However, what do homeowners whose windows do not meet such requirements do? Calmly, this does not mean that they immediately have to replace the entire window joinery. The rules will only apply to investors who obtain planning permission in 2021.
What does uw factor say?
The Uw factor tells us how much heat escapes from our homes through the windows. The lower the value of the coefficient, the better, because we suffer less heat loss. The joinery we offer guarantees uw at a much smaller level than the regulations dictate. Depending on the lines and solutions we use in ours, the coefficient can be up to 0.71 W/m2K.
In conclusion, investors who have obtained a building permit in the coming year and have decided to choose our windows can sleep peacefully and do not have to worry about the revision of the building regulations.
