Wood itself has superb natural insulation attributes which the Classic series frames combine with today’s high tech glazing. The right combination of triple glazing and warm edge spacers means our Classic timber line can achieve Uw-values down to 0.84W/m²K, nearing passive house standards. Excellent weather resistance is guaranteed through our aluminium water drainage channels and factory sealing.
Robust German hardware easily stands up to repeated use and allow for heavy sashes, providing excellent burglary protection and a high degree of longevity. Fail-safe locking handles ensure smooth operation, and a wide range of handle styles are available to suit any project.
