Sealing
burckhardt’s glide sliding windows are tested and certified regarding air permeability, wind load and water tightness in heavy rain. We have reached outstanding physical construction values. We thus meet high requirements concerning wind and weather protection. The brush sealing with a central membrane, various EPDM-sealings and sliding profiles secure a high tightness.
They additionally ensure high protection regarding sound emission together with an easy handling.
The small, interlocking middle profiles (labyrinth profiles) ensure an excellent tightness in closed position and are characteristic for the puristic look of the sliding window system. The middle profiles are available in two sizes:
- 26 mm – visible width and
- 38 mm – visible width
