Assessment of non-ventilated air gap in sloping roof with thermal insulation above wooden rafters
Original language description
When designing a passive house, the emphasis is not only on passive measures consisting mainly of thermal protection and stability of the buildings, but also on the price demand of each of the proposed structures. At present, new construction solutions are often encountered in construction practice [1]. These solutions are not yet tested. The paper deals with energy-efficient buildings in terms of reducing building heat loss. One such solution is to use thermal insulation above wooden rafters. Using the thermal insulation above the rafters eliminates thermal bridges [2]. If the thermal insulation is situated above the wooden rafters in combination with the suspended ceiling construction, a non-ventilated air gap is created. In order to avoid disturbances due to water vapor condensation, a moisture stop must be installed in the roof structure. This vapor-proof membrane must be installed as close as possible to the inner surface of the sloping roof. The paper deals with the assessment of the sloping roof structure with thermal insulation above the rafters with non-ventilated air gap, in terms of building physics. (C) SGEM2019.
