Flip – Flap doors MOD FFPU1-2 of dual inside-out movement, single leaf or double leaf with BAYER Germany polyurethane insulation, free of chlorofluorocarbons (CFC & HCFC FREE), with sound insulation and thermal insulation properties.
The thickness of the door is 40mm, lined with galvanized German steel sheets coated with plastisol of 200 microns thickness and bearing perimetric aluminum profile (the frame) mounted opposite and pressed together with the polyurethane in order to maintain the door always flat.
A special insulating EPDM rubber with excellent grip is placed on the outer perimeter of the door. In case of double leaf doors, another special rubber is placed at the middle of the two leaves that allows the correct opening – closing of the door, the good adhesion between the leaves and prevents the risk of injury of the fingers of the user.
It is adapted to the panel with a frame from angular PVC and CPR counter frame, “hugging” solidly the panel on which the leaves of the door are mounted. They open inside-out and close immediately “after passing”, blocking the passage of insects, dust, odors & other and they remain open to 90 degrees angle.
Each door has fixed oval porthole mounted and has special protection ails (bumpers) from polyethylene, under the porthole, inside – out. This material is extremely resistant to impact and to grease and acids and is of modern design and aesthetics.
