ComfortHush™ is an acoustic performance glass, which also features a durable Low E (low emissivity) coating. It is available as a 6.5mm and 10.5mm Grade A laminated safety glass that uses a special 3-layer acoustic PVB laminate that is specifically designed to reduce sound transmission.
The inclusion of a durable Low E coating also provides improved energy efficiency performance, by helping to keep homes and buildings cooler in summer and warmer in winter.
Viridian VLam Hush™ is a laminate that uses a specially developed interlayer to dampen noise, providing enhanced sound insulation performance. This means that thinner and lighter glass can be used for equivalent acoustic performance. VLam Hush reduces the coincidence dip of standard monolithic and laminated glass.
Viridian VLam™ consists of two or more sheets of glass bonded together by heat and pressure with an interlayer of either PVB, EVA or a specialist high strength ionoplast interlayer.
Resin Pour or Cast In Place (CIP) is another form of lamination. Edge tape is applied to the edge of the glasses before a liquid resin is poured between the two sheets. The resin is cured under UV lights. Only available in New Zealand.
The result is a durable, adaptable high performance glazing material that can provide solutions to many architectural applications. Within the Viridian™ range there is a wide variety of laminated glass options
The following tables take the recommended design sound levels from AS/NZS 2107 for both recommended and satisfactory levels and lists the glass to be used to achieve the desired sound level at the inside of the glass. Satisfactory refers to the highest levels of noise in the room which is believed tolerable by AS/NZS 2107 for the activity being undertaken in that room. Therefore the recommended solution is more desirable for the occupant than the satisfactory solution.
