Glazing
It’s vital to choose the right glazing to ensure your home has good thermal insulation. The thermal insulation value (U) of glazing is measured in W/m2. Raposo’s PVC windows are fitted with original double glazing (Ug=1.0W/m2K). This allows you to save the equivalent of up to 49L of fuel per m² of glazing annually (compared to single glazing).
