The Internorm HF 310 window is a combination of timber and aluminium, with a highly insulating thermal foam between the frame and sash. Natural timber and weather-resistant aluminium create a high performance window that is suitable for Passive House projects. The HF 310 window can be combined with the KF 410 uPVC window due to the same flush design of the aluminium cladding.
