Multi-layers polycarbonate panels are naturally good thermal insulation materials. But their thermalinsulation can be significantly improved if they are used in pairs, as in double glazing, and if the spacebetween them is filled with a product aimed at blocking air movement but keeping a very visualtransmittance. Such a product has been designed, with a U-value close from 0.65W/m2.K. The finalmaterial is however translucent, and not transparent. It appears attractive to use it as a component ofexternal walls or ceiling. This paper describes thermal and optical properties and possible use inbuildings. A critical analysis is proposed to discuss the interest of this technology to reduce energyconsumption in buildings.
