How IGU's keep you warm in Winter and cooler in Summer
How you can use IGU's to reduce Noise
The manufacturing process of IGU's

IGU's are the way to go if you are looking for increased value from your dollar. An IGU is a complex appliance, which if made* and installed correctly, will give many years of trouble free service.

IGU's are two panes of glass, bonded to a spacer and separated by a sealed air space. Because this space is fully sealed, it acts as an insulator, keeping your home at a comfortable temperature in both Summer and Winter.

*All IGU's manufactured by IGMA members are guaranteed for ten years. The members adhere to an agreed set of procedures to ensure continuous high quality.

For Increased Comfort
Ordinary windows may not insulate well, allowing warmth to escape in Winter and admitting heat in Summer. A modern home with ordinary glass can lose up to 50% of its heat through windows.

Insulating Glass Units significantly cut heat transfer through windows in two ways:

• They trap a layer of sealed dry air, which acts as a natural insulator.
• They reduce the transfer of heat by radiation, where the glass itself warms and passes heat.

Because the sealed air in the IGU is dry, there is no condensation in the unit. Condensation on the inside of the window is also minimised.

How IGU's keep you ...

Warm in Winter ... Cooler in Summer

By cutting the transfer of heat from the warm to the cold side of the window, IGU's can significantly cut loss of warmth in cold weather

For even greater performance, Low Emissivity (Low-E) glass can be incorporated into IGU's. An invisible, metallic coating on the glass enhances its insulating properties, providing greater energy efficiency and comfort
By reducing heat gain from hot outside air, IGU's can keep you cooler in Summer

Heat gain through windows in Summer depends on many factors, such as shading, direction of window, outside temperature, even wind speed.

Where windows are in direct sun, or subject to high radiated heat, tinted (toned) or reflective glass in an IGU can greatly reduce heat gain by in effect shading the window.
Incorporating Low-E glass as the inside pane not only improves performance but also helps retain warmth in Winter.

IGU's for Reduced Noise
Because of an IGU's sealed air space, a unit can be an effective insulator against unwanted noise.

Windows in most homes contain ordinary 3mm glass. Properly selected and installed IGU's can reduce unwanted noise by up to 65% compared to ordinary glass.

The right IGU can be designed to solve your noise problems by:

• Increasing the thickness of the air space gives greater noise reduction.
• Using different glass thickness in each pane, or incorporating laminated glass, can cut noise transmission.

Noise can vary, so your choice of IGU may vary. Your glass or window supplier (or IGMA member) can advise the right IGU design to solve your particular noise problem.

For effective insulation against noise, all possible entry points for noise in your home should be checked and sealed off. This includes gaps in and around window frames, wall and ceiling vents, loose fitting doors and windows, gaps in walls and floors and the construction and insulation of walls and ceilings.

How you should use IGMA Insulating Glass Units
Use IGU's in association with other insulation and transform your home into a warm, comfortable haven in Winter and a cool, delectable breath of fresh air in Summer - cutting the cost to you in keeping it that way.

A well insulated home takes less energy to heat and cool and will substantially lower your energy consumption.

Only buy IGU's with an official IGMA label and ensure IGU's are installed in accordance with IGMA Installation Instructions

Only use IGU's manufactured by an IGMA member.
