A warm sill

The so-called warm window sills are most often sill profiles made of hard XPS extruded polystyrene or EPS hard polystyrene. These profiles allow for adaptation to a specific window system. Warm window sills significantly contribute to the improvement of the thermal conditions of the building. The thermal and energy properties are significantly improved here, which in turn contributes to the overall condition of the building. These profiles eliminate the problem of blow-by and water infiltration between the window and the sill .
