Double-glazing advantages

Double glazing for heat and sound control is effective, attractive and economic. Because windows with a single thickness of glass are the home’s weakest defence against escaping heat and intruding noise — and because most modern homes have windows • of a generous size — double glazing makes good sense. Double glazing means windows have two thicknesses of glass just a little apart. The air trapped between the two panes provides an insulating barrier. Less heat flows out, less noise enters. So, the home is quieter with a reduction in heating costs. Double glazing will keep the home cooler in summer too.

The installation of Thermosash double glazing does not mean existing windows have to be replaced. Thermosash simply fit a second window behind the prime window to give the two thicknesses. This can be achieved in 99 per cent of homes.

Different window styles can be installed by Thermosash to match existing windows and all are made from high-quality extruded aluminium sections, clear or bronze anodised and to tolerances finer than trade specifications. Excessive noise is unhealthy. Specialists

know this and warn that it can cause nervous tension while seriously impairing hearing. The installation of Thermosash will reduce noise levels by at least 50 per cent for the window area itself, and this gives an improvement in the noise insulation value of the building structure. This is a particularly important aspect in homes, schools, offices, hospitals, and hostels sited on or near busy roads, industrial areas, airports and other areas of highdensity activity. Tests have shown that

Thermosash double glazing is twice as efficient as single glass in preventing heat loss. It also conserves heat stored in a room during the warmth of the day, so heating only has to be switched on much later. Conversely, double-glazed windows will keep inside temperatures down on hot summer days. The insulating layer of air between the two thicknesses of glass keeps the inner pane much warmer than the outer one. Thus, messy condensation will be virtually eliminated.
