Inverted flat roof waterproofing combined with a thermal insulation is essential for a buildings waterproofing and energy saving thermal insulation. The MARISEAL SYSTEM® inverted flat roof waterproofing method offers a simple build-up waterproofing, that features a protected waterproofing membrane and loose laying insulation boards.

The inverted waterproofing insulation system is applicable for all types of flat roofs, as it offers an efficient solution for new construction but also for renovation of old flat roofs as is it possible to install an inverted roof over an existing roof build up.
