Window double UPVC-ALU Internorm KF310 3

With a construction depth of only 71 mm, this window is very slim. The rounded edges of the sash and frame perfectly match the home soft design style. In addition to the classic uPVC option, the KF 310 is also available as a uPVC-aluminium composite window. The aluminium cladding on the outside is available in many colours. The new 6-chamber frame profile provides even better thermal insulation. Three continous gaskets protect the interior from moisture and also improve thermal and sound insulation.
