Retrofit double-glazing system catches on
By Sally Rae
A Dunedin-designed double-glazing system, which started as a concept drawn on a paper pie packet, is now being sold in Australia. Thermawood, a patented retrofit double-glazing system for existing timber joinery, was the brainchild of Graeme Clarke, whose background was both as a joiner and a glazier. The system was developed around drainage.
