Sw 80 Double Side Seal 2
Double side seal

The high insulating effect is achieved by the double side seals between the frame and door leaf.

Sw 80 Floor Seal
Floor seal

The rot-proof bottom seal made from non-freeze EPDM rubber profile smooths out floor unevenness and protects from cold and damp.

Sw 80 Top Seal
Top seal

It securely closes, seals and insulates the door in the lintel across its full width.

Our products attain a great thermal effect by combining many constructive features: The double-walled, 80 mm thick steel panels are coated with highly-insulating polyurethane (PU) foam and thermally separated from one another.

In addition, the door leaf is equipped with a rot-free double seal. In this way, it achieves an extremely low UDvalue of 0.58 W/(m2K)*. A quality that effectively minimises cold or heat losses and tangibly reduces energy costs.

* Refers to a closed SW 80 door with an area of 5 x 5 m.
