Title: Varmtak på småhus
Authors: Andersson, Kristoffer
Abstract: SAMMANDRAG The usage of moisture proof constructions when building detached houses is important. One moisture proof construction that could be used is a warm roof with corrugated sheet. If this type of roof is going to be able to be used on detached houses both the technical and the aesthetic requirements need to be fulfilled. The purpose with this bachelor thesis is to see if it is possible to fulfill these requirements. Using a reference group has seven types of warm roofs been investigated. The seven roof types that has been investigated is felt roofs, steel sheet roofs, green roofs, roofs with roof tiles, felt roofs with two step sealing and felt roofs with triangular strips. The work started with drawing detailed drawings of all the different roof types. When all the roof types had been drawn the work was continued by drawing details of the ridge and the meeting between the roof and the external walls. The results show that it with some adjustments is possible to use this kind of roof on detached houses with a roof pitch of 45°. Two of the roof types that was investigated is more difficult to use on 45° roofs. The green roof can’t be used on roofs with higher pitch then 27° without special adjustments being made. The other roof type that was difficult to get to work was the roof with roof tiles. Attaching the battens without damaging the roof felt is something that is hard to do. In this report there are some examples of how this might be achieved. A warm roof like this might become more expensive than a regular roof but if it’s constructed in the right way it’s more secure against moisture, has better U-value and fewer thermal bridges.
