Whether your project involves installing a new roof, terrace or extending the life of your existing roof with preventative maintenance, we understand the importance of these operations.
Roofs being the most exposed part of a building, require proper structural composition to increase the life expectancy of the roof in its entirety.
In flat roofs with conventional build-up, the thermal insulation is placed above the structural deck but below the water-proofing membrane.
The membrane is thermally isolated from the rest of the roof construction, thus exposed to wide temperature fluctuations with increased risk of premature failure. When applying the “inverted” roof concept, the risk of the failure is minimized. The thermal insulation boards placed on top of the roofing membrane provide protection against a number of damaging factors:
- Temperature extremes: with inverted roofs the temperature of the membrane stays within a narrow interval.
- Climatic impacts and UV-radiation,
- Mechanical damage including impacts during the construction period, use and maintenance.
- Waterproofing membrane on the warm side of the thermal insulation acts also as a vapour barrier.
