JET HEATSTOP 2-schalig

HEATSTOP dome rooflight double-skinned

For optimal heat protection under your flat roof


The temperature in internal rooms can increase rapidly in Summer. To guarantee a pleasant room climate despite utilising skylights, our tried and tested standard dome rooflight is also available as a double-skinned HEATSTOP version.


Due to the external glazing made from PLEXIGLAS HEATSTOP®, this dome rooflight optimally protectsagainst heating caused by solar radiation. You can simultaneously arrange for natural ventilation via the dome rooflight when you then select the appropriate opener fittings from our extensive range of accessories. Or you can decide for the application within the framework of a SHEV system. Whatever your requirements – you always have the correct product with the modular expandable HEATSTOP.


This dome rooflight also simultaneously creates an architectural highlight on your flat roof. This is possible both in new construction as well as for retrofitting during refurbishment.
