Vapor open insulated systems for pitched roofs in Europe
The construction of a pitched roof has evolved significantly during the last 20 years. It has not been visible from the outside, but behind the tiles things have changed. The oil crisis in the 70s could be considered as the start of this change. The economical necessity to save energy has been reinforced later by ecological needs. The construction technology was directly concerned, focusing on decreasing heat losses in building, and using more environmentally friendly materials. However managing heat losses requires also managing moisture transport through the building walls and roof. Lacking to consider this aspect would lead to dramatic condensation problems. This presentation describes how and why the change from traditional 'vapour closed' to 'vapor open' or 'breathable' roof system has been successfully implemented technically and commercially. Using the flash spinning technology has revolutionized the way of building pitched roof system. The necessity to continuously improve the thermal insulation of the roofs has driven the introduction of 'high diffusion' membranes with good barrier property against wind and rain. Traditional products do not give the flexibility and ease of installation that a light product can offer. The characteristic of a 'vapour open' underslater are diverse. The flash spinning technology has permitted, in one layer, to achieve the right balance between the 4 essential properties: strength, breathability, weather resistance, and durability. The concept of designing the thermal insulation of the pitched roof as a whole system comprising a roofliner, an insulation layer, and a VCL, is a necessity. Since one cannot prevent moisture transport to occur, it is important to control it. The combination of thermal insulation material with 'vapour open' roofliner and VCL is optimizing the thermal resistance of the roof, preventing any potential damages caused by trapped moisture or condensation. The approach to market of these systems offers some potential synergies between the producers of 'vapour open' roofliner, thermal insulation material, and VCL's. They provide to the house owner a 'healthy' dry roof and to use the volume under the roof as a comfortable living space.
