Energy Ratings

Save energy. Sleep safely, too.

Heat loss matters. Thermal efficiency, U values and energy ratings.

Even though windows comprise only 8% of the external surface area of a home, they account for almost 40% of the heat lost. Advanced aluplast engineering lets you dramatically reduce heat transfer through glazing and frames.

The U value of a window indicates how well the glazing and frame provides thermal insulation. The lower the U value, the better the insulation qualities of the window. By reducing the heating needed within your home, fuel savings can run in to hundreds of pounds every year.

aluplast can manufacture window specifications capable of U values under 1.00. Featuring five chambers, the latest aluplast Ideal 70 system comfortably achieves an ‘A’ standard Window Energy Rating (WER) with a double glazed unit. With a 40mm triple glazed unit instead, the system delivers a WER of ‘A Plus’.

A+ energy rated double glazing

Heat energy is transferred from homes by conduction through the walls, floor, roof and windows.

Heat loss through windows can be reduced using thermally efficient window frames and double or triple glazing. Heat loss through conduction is then reduced significantly.

Further improvement in reducing heat loss can be achieved by introducing alternative more efficient spacer bars and gas filed glazed units.

Security first. Protection against break-ins.

According to the police, most burglars force open doors and windows by lifting, hammering or drilling. aluplast PVC windows are designed to protect your family and your home from intruders. Window and door resistance to various levels of attack can be compared thanks to new European standard, DIN EN 1627.

All aluplast window and door profiles, glazing and hardware resist the most demanding assaults – the use of power tools for instance – for a minimum of 15 minutes or longer. Stringent testing has gained the aluplast Ideal 70 system PAS24-2012 and BS 7950 from the British Standards Institute.
