P4000 LS - PVC doors

Thermal insulation Uf

from 0,95(W/m²K)

Large windows allow you to eliminate all restrictions, save space and freely shape the space in your home. Rooms full of light, closeness of nature, lack of barriers and optimal use of living space are new perspectives in interior design. Special fittings mechanisms allow you to move huge wings using minimum force. Turning the big handle down, from the closed position, raises the wing by a few millimeters, releasing the pressure of the gaskets and the enabling you to move the wings freely.
