Variant of PE 78, which has a four-chamber design - similar to the window system PE 78. It is designed for use in structures with particularly high requirements for thermal insulation.

The high insulation levels are achieved by the use of a special insulation inserts ans so: PE 78+version with closed glass chamber Uf value of 1,1 W/m2K. PE 78HI the top variant - with special insulating inserts "aerogel" in the profile chambers, achieves Uf value 0,9 W/m2K.
