Double Glazing

Designed to last, our uPVC Double Glazed windows & doors have been made and tested for the harsh Australian climate. Give your home a facelift while saving on those energy bills.

Providing outstanding levels of thermal insulation and overall energy efficiency, high performance uPVC window systems are the ideal sustainable solution for reducing energy consumption.

​

Here at NSDG, we utilise a high performance double glazed system. Our high performance Kömmerling uPVC windows are designed to reduce heat transfer and reduce noise by trapping air between two panes of glass. This trapped air creates an insulating barrier which provides 2 main functions- prevention of heat loss through barrier insulation, and reduction of noise transfer.

​

Merely replacing old windows with modern, insulated uPVC systems can not only make distinct improvements to your levels of comfort and quality of life, but it can also make perceptible savings in your heating costs. Energy provision is expensive, and it’s getting more so.
