Multipor flat roof insulation

Flat roof insulation

In the thermal insulation of flat roofs, the insulation materials used must meet high requirements. Multipor is an extremely pressure-resistant, non-compressible mineral insulation board - perfectly suited for the insulation of flat roofs. Multipor mineral insulation board are especially suited for walkable surfaces and flat roof structures with high fire-protection or ecological requirements. The mineral insulation boards can be combined with almost any insulation system. Multipor mineral insulation boards and Ytong roof panels: the perfect combination in the Ytong combination roof.

Insulating flat roof structures – mineral based and ecological

The Multipor mineral insulation board is environmentally sustainable and consists of the mineral-based raw materials sand, lime, cement, and water, which are mixed with a pore generator. These materials make Multipor an environmentally friendly building material. For its exemplary environmental sustainability, the Multipor mineral insulation board received the certificate of the German Institute for Construction and the Environment (IBU). Multipor has also been awarded the natureplus quality certificate as a sustainable and future-ready product. The certification of Multipor mineral insulation boards confirms that the product is toxin-free, does not generate any toxic emissions, and has an excellent eco-balance – from the natural resources used, to production, and finally disposal.

Processing of flat roof insulation

There are various methods of processing Multipor mineral insulation boards for flat roof insulation. Both flat and tapered boards are available, and these can be perfectly combined and adapted to any tapered roof system. The insulation system can be processed using the customary and usual installation variants. With insulation material thicknesses above 240 mm, a multi-layered installation is required. Each additional layer of Multipor mineral insulation boards can be bonded with hot bitumen, insulation material adhesive foam, or in this case also Multipor lightweight mortar.
