PE 78N/78HI

Three-chamber system with “euro” standard groove and groove used in windows and balcony doors made of PVC or wooden profiles. It is dedicated for constructions with very high thermal requirements.The structural depth of profiles for frames is 78 mm, for sashes 86 mm.

Thanks to multi chamber thermal breaks (42 mm) and two component central gasket we can obtain high thermal insulation. In PE78N Uf frame heat transfer coefficient equals 1,7 W/m2K. In more insulated version PE78N+, with closed glass chamber, the Uf value equals 1,3 W/m2K.
The system allows to use wide range of hardware and ease the mounting. Three-chamber profile construction of PE78N system, provides large stiffness of profile, which allows accomplishing constructions of large dimensions.

PE78N HI

A variant of PE78N system intended for the constructions of a particularly high requirements for thermal insulation. Thanks to the special inserts there can be obtained very high thermal insulation.

In more insulated PE78N HI version – with closed glass chamber and insulating insert, the Uf frame heat transfer coefficient equals 0,9 W/m2K. In the most insulated (PE78N HI+) version – with closed glass chamber and insulating insert made of aerogel, the frame heat transfer coefficient equals 0,7 W/m2K.
