TOP-90 PLUS dome rooflight

The plus point for energy efficiency on your flat roof

Energy efficiency is also an important topic on flat roofs. That is why we have developed the TOP-90 PLUS dome rooflights with a multi-wall sheet, which are not only versatile in their application, but have also proven their worth in energy-efficient new buildings and refurbishment work. In addition to their high functionality, these dome rooflights are also an aesthetic highlight on your industrial flat roof thanks to their attractive design.

The TOP-90 PLUS is available both as a rectangular shape as well as a square shape in over 55 nominal dimensions.

The tried and tested TOP-90 standard dome rooflight can also be easily retrofitted to an energy-efficient PLUS version. This is done by simply fitting the internal polycarbonate 16-mm multi-wall sheet in opal or clear finish.
