GLAZING REDUCES TRAFFIC NOISE


A window and plastic panel combination that quietens noise from outside buildings has been developed by Christchurch-based Magic Seal (NZ). The system cuts down noise better than double-glazing because it deflects sound differently, says managing director Trevor Bunting. “Double-glazing consists of two sheets of glass, each reacting the same way to sound,” Mr Bunting says. “Glass and thermal panels react differently from each other, resulting in significantly reduced noise.” The product’s noise-muffling benefits were developed in a research project that involved the University of Canterbury and was part-funded by Technology New Zealand. “We were aiming for a product that would cut down on outside noise better than double-glazing,” Mr Bunting says. “The university’s mechanical engineering department fired sound at a control panel, and at our sample window and panel which were set about 40-50mm apart. They found a huge drop in truck-rumble – about 10 decibels. The noise was barely audible.” The window panel is magnetically sealed against the window frame and is made of materials that won’t rot or stain. It is energy-efficient, controls condensation, almost eliminates fading of fabrics from sunlight, and is almost invisible when installed. Mr Bunting says the results of the research funding from Technology New Zealand – part of the Foundation for Research, Science and Technology – gave the company the confidence to proceed with production. “We need to export because there are overseas markets for this,” he says. “The research has resulted in a product that will perform significantly better than what is currently available and thus opens the door to new export markets.” Magic Seal started up in 1989 and employs three people. It imports and makes up magnetic thermal insulating windows and magnetic insect screens. -ends-
