KERTO-RIPA THERMAL COMFORT AND COVERING In Finland, where winters are of the coldest in Europe, we have of course been taking in consideration how to insulate buildings against low temperatures. The cavities of Kerto-Ripa slabs can be partly or fully filled with insulation material. This normally ranges between 100mm and 400mm of insulation, depending on the type of insulation material, the architects and engineers needs to comply to local regulations and their drive to build efficient and green buildings. In Central Europe roofs are often designed as “warm roofs” with the main part of the insulation above the slabs. As a rule of thumb 1/3 of the total thermal resistance is put inside the cavities and 2/3 on top. With the help of specialist engineers, able to analyse the roof components utilizing a dynamic modelling software, you will be free to design customized solutions. The choice of connection details and type combined with the position of a vapour barrier is also essential. Temporary weather protections are highly recommended and can be applied on demand. A large scale of covering are possible. Green roofs, PV roofs and accessible roofs are also allowed with appropriate materials and details.
