What chambers and depth give you
Chambers are the air cavities inside the profile. More chambers and a deeper profile mean better thermal and sound insulation. Depth also sets the glass unit thickness: Winklaus 60 takes units up to 24 mm, Winklaus 70 and 75 up to 28 mm.
Winklaus 60 — the sensible choice
4 chambers, 60 mm depth, 68 mm frame and 58 mm sash. 20 mm (4+12+4) or 24 mm (4+6+4+6+4) glass units, or single 4 mm glass. A reliable, cost-effective option for standard homes, social housing and office buildings.
Winklaus 70 — the sweet spot for flats
