Exterior Security Doors DAF for houses, semi-detached houses and other buildings. They are water and weather proof and are equipped with a non-freezing sash.
The sash of the door is made from folded steel profiles and external protective 2 mm thick steel plating. The metal edge of the sash is covered with humidity-proof veneer. Stone wool and additional polystyrene filling protects the door from over-freezing and from condensation of humidity.
Double insulation spacer is used on the sash and inside edgings of the door.
Inside edgings are 30 mm thick, and they are wrapped in polystyrene that isolates the passage of the cold weather between the metal jamb and inside of the premises.
The jamb is made from 50 x 65 mm folded steel profile. It is filled with hard stone wool, so that the inside condensate would run out; the humidity evaporates through air vents. The total thickness of the jamb together with edgings is 95 mm.
The security door is equipped with one lock system.
