| dc.description.abstract | At the Norwegian Building Research Institute, we have been working with window research and development for many years and have made it one of our main fields of interest Different types of specialized testing equipment have been developed, built and bought for this purpose. Tests and studies are made both of the complete product and of all the components used for manufacturing the window: Glass, sealants, surface treatment, weather stripping, fittings, aluminium-, plastic- and wooden frames and sashes etc. They include durability, weather resistance, energy consumption,
general physical and mechanical properties etc.
Tests and studies for new development are made in, among other things:
Driving rain apparatus
Wind pressure apparatus
Apparatus for simulated, accelerated ageing
Special equipment for testing durability of plastic windows
Ageing of sealed glazing units apparatus
Guarded hot-box for studies of energy transmission
The papers in this publication are examples from recent work at the Trondheim division of the institute. It is our hope that this volume will bring the reader an understanding of the importance of this field of development, and at the same time same useful practical knowledge about windows as they are produced and used today.
The papers were originally presented on a congress in Gothenburg, arranged by the Swedish Council for Building Research in 1984. | |
