The semi-insulating doors of the VVPE line (to-and-from in high density polyethylene) are designed for installations in air-conditioned rooms with minimum working temperatures > 12 °C, ΔT < 12 °C, U.R. < 60% they can only be used as service entrances and not for uses requiring a hermetic and thermal seal.
They can be supplied for installation on panel or brick wall.
High density polyethylene is a sturdy material with excellent rigidity and resistance to impact.
For this reason VVPE doors are particularly suited to environments where there is a heavy traffic of trolleys; polyethylene is also a non-toxic material and it has good chemical resistance.
They consist of 3 essential parts as specified below:
Frame in anodized aluminum with an invisible fastening system.
Door panel consisting of a slab of high density polyethylene 2 centimeters thick; reinforced on the hinge size with an upright 4 centimeters thick in the same material. Strips in soft, transparent PVC are applied along the 2 vertical edges to prevent crushing the fingers. The transparent window measures 30 x 60 centimeter. The hardware consists of 2 plastic hinges with return spring and door stop at 90°.
Counterframe in anodized aluminum with invisible fastening system (not supplied for installations on brick wall).
On request, we can also supply double leaf doors.
On single leaf doors the client must specify whether the hinges must be on the right or left with respect to the outside of the door, because the polyethylene slab has a different surface finish on the two sides.
