Reliability in a system
The diagram shows a sample cross-section through the three functional layers of a pitched roof. The exact way in which these layers are executed in each individual case will depend on the specific requirements for the roof. You can always rely on Bauder system solutions to provide the ideal combination.(kopie 1)
Below the roof cladding, a subroof membrane, underlay or sarking membrane provides a second protective layer against moisture and the effects of the weather. This prevents driving rain, fine snow and melt water etc. from penetrating the roof structure and thermal insulation.
Thermal insulation (2)
Efficient thermal insulation saves energy, reduces emissions, and lowers heating costs while at the same time making your home more comfortable. For some years now, specifications for roof insulation have been getting stricter, not least because of new energy saving regulations.
Vapour barrier/check (3)
To prevent moisture penetrating from the interior of a house into the thermal insulation, the roof system must include a vapour barrier or, depending on design, a vapour check. Otherwise, as moisture in the internal air condenses, there is a risk that mildew and mould will form. Also, if the thermal insulation becomes damp, its performance is significantly impaired.
