Double glazing for heat and sound control

By R. .A. .Alexander, manager of the Building Centre. Heat loss and energy conservation have never been more important than today when costs are sky-rocketing.

Home-owners are increasingly searching for ways of making that energy dollar stretch a little further. For the new home, the solution is relatively simple, under the mandatory insulation code; hut the owner of. an existing home faces a major problem With some 20 per cent of heat lost through the windows. this is an obvious starting point. Double glazing makes good sense because windows with a single thick-’ ness of glass are your home's weakest defence against escaping heat and intruding noise.

Double glazing means you have windows with two thickneses of glass, just a little apart, and the trapped

air provides an insulating barrier. Now. with the Thermosash systems, you can shut in warmth and keep out noise effectively, attractively, and economically. Less heat is lost and less noise enters, which means a quieter home and reduced heating costs. In summer, double glazing helps to keep your- home cool. y The installation of Thermosash double glazing does not mean existing windows have to be replaced. They simply fit a second window behind the prime window, to give the , two thicknesses. Different window styles can be installed to match existing windows and all are made from clear or bronze anodised aluminium to tolerances higher than trade standards.

Sliding units provide excellent ventilation . without

sacrificing sound insulation. The layer of air between the two thicknesses of glass keeps the inner pane warmer, which in turn helps to reduce condensation. The Thermosash units can be easily cleaned as they are designed for access oh the inside face of both

primary and secondary panes. A special display of Thermosash double glazing can be seen at the Building Centre. More information is also available at the centre, including how to install the system yourself.
