Insulation of flat roof surfaces and panel-built flats
With traditional applications of insulation using a bituminous surface poured on in hot liquid form over 100m2, 120 and 180 FM bitumen welding bitumen is found. The size of this welding depends on the size of the parapet wall, the vents and positive / negative number of corners. The workflow using bitumen welding for the former three (parapet walls, vents and corners) cannot provide perfect security. Thoseprofessionals engaged in this kind of activity are in the know.
In the case of flat roofs, the most reliable form of insulationis sprayed polyurethane thermal insulation and waterproofing, tread-proof foam, as it forms one large, contiguous layer structure that is 100% waterproof, without any instillation holes or splicing points,resulting in the building being able to overcome building expansion problems because of the flexibility the new foam surface provides, which enables it to move together with the wall onto which it has been applied. For this reason, any threat of leaking or the formation of heat bridges is practically none. This technology can be used for the insulation of both new and old flat roofs, as well. There is no need to use of the old technology orfor poor insulation removal, which results in considerable financial savings. The external heat insulation and waterproofing should be protected against harmful UV rays, for which our company offers a special UV paint against, but of course, other products can also be used.
The result: high-quality design, improved comfort and lower heating and cooling costs.
