Laminated Glazing Thickness

Low level glazing not covered in 1 or 2 above other glazing that is wholly or partially within 800mm from floor level.
Laminated glazing thickness. Pvb laminated is the more commonly used variety. Minimum annealed laminated single lite or unit size. Weight of the glass make up can determine interlayer thickness. Including a structural thermally improved aluminum thermal barrier air spacer in the insulating glass can improve acoustical performance by reducing the transmission of exterior noise.
Two or more sheets of glass are bonded together with one or more layers of polyvinyl butyral pvb a plastic interlayer in sheet form. A standard laminated glass gives similar effect with the additional benefit of safety. One can obtain this effect with a thicker monolithic glass with additional weight and glazing thickness. For all glazing types the minimum nominal thickness shall be 1 4 inch 6 4 mm.
Glazing adjacent to doors windows side panels wholly or partially within 300mm of the edge of a door and which is also wholly or partially within 1500mm from floor level must be safety glass. Pvb laminated safety glass. The ability to resist various kinds of penetration is dependent upon a number of factors including thickness of the glass and the. Laminated glass of 6 mm using 030 interlayer and two lites of either 2 7 mm or 3 0 mm 6 4 mm overall when using 3 0 mm glass is probably the most common make up of safety glazing using laminated glass for residential applications.

Laminated glass is a type of safety glass that holds together when shattered in the event of breaking it is held in place by an interlayer typically of polyvinyl butyral pvb ethylene vinyl acetate eva or thermoplastic polyurethane tpu between its two or more layers of glass. The glass plies may be of equal or unequal thickness.
In general the acoustic attenuation of a glazing is obtained by asymmetric thickness of glass. The most important characteristics of laminated glass are fall out protection due to the ability of the interlayer to support and hold the glass when broken as well as the reduced ability to penetration the opening. 6 x 6 minimum heat treated laminated single lite or unit size.
