ABSTRACT

A study has been made of gaskets in glazed areas facing both south and north in the roof covering the pedestrian precincts of Skärholmen Centre, Stockholm. Gaskets in glass parts facing south are subjected to more severe temperature stresses and solar radiation than those facing north. If the gaskets are not tight water may leak into the glazed space. As leakages can result in damage to the building, and the replacement of the gaskets is rather expensive, the gaskets must be durable.

After 6 years of exposure no degradation of importance could be confirmed from swelling tests or from mechanical tests, but at the same time the permanent set was considerably greater for gaskets facing south. These results indicate that this gasket has satisfactory durability.
