Development of a thin light double glazing with improved acoustic insulation properties
The most usual way to do acoustic rehabilitation of facades is changing the existing windows. One of the main problems encountered is the weight of the new windows, specially in old buildings without lifts. Up to now, the only solutions were the use of double glazings comprising at least one thick glass, as 10+4 or 10+6 with 6 to 16 mm space. A new type of double glazing has been developed, using special laminate and thin glass. An important rule concerning interest of laminates in double glazings is that the thickness of the laminate must be smaller or equal to the thickness of the monolithic glass. This has been put into evidence by modelisation. So, the only way to solve the problem was to decrease the thickness of the laminate, that is to use laminate with very thin glass. The final product is 22-1+4. 22-1 means 2x2 mm glass panes assembled with special acoustic interlayer. The acoustic performance of this product is equal to usual acoustic 10+4, but it fits in the same windows and the use is the same than standard thermal 4+4. Some additional specific problems have been studied, as maximum dimensions and conditions of use, because mechanical properties and wind resistance of thin glass are smaller than those of ordinary 4 mm glass.
