Double or triple glazing: which solution to prefer?
Glazing plays a crucial role in the energy performance of windows.
Double glazing
Double glazing is currently the most common solution. It already provides good thermal and acoustic insulation.
In many renovation projects in Belgium, it represents a good compromise between energy performance and installation cost.
Triple glazing
Triple glazing offers even better insulation. It is particularly recommended for ambitious energy renovation projects or for homes located in areas highly exposed to cold.
However, its installation sometimes requires sturdier frames and can represent a larger investment.
