IGU for double glazed bifold windows

 
         
 

Double Glazed Units or IGU are the intelligent choice for consumers who appreciate performance and quality, and are supplied based on thermal or acoustic requirements.
We use 32mm insulated sealed units made locally and fulfilling all the requirements of Australian Standards for glass and glazing. Glazing options include Float, Laminated, Toughened, Low-e, Tinted and Obscure glass.
The air space between the glass layers may be filled with air or an inert gas, such as argon or krypton which improves thermal and acoustic performance and reduces greenhouse gas emissions by saving energy!

   
         
 

There are many benefits to utilizing double glazing in your home, and apart from substantial improvement in thermal and acoustic comfort our customers report a reduction in energy costs, elimination of condensation, a considerable decline in fading of furniture and artwork and improvement in visual attractiveness and increase in the resale value of your home. In addition, for clients with older homes that retained original features, the existing glass may not meet the current Australian standards and may even be deemed unsafe. This is especially true of doors & bathroom windows, where safety glass and obscure glass, respectively, is not only desirable but mandatory! Take this opportunity to upgrade the windows and doors in your home and enjoy the benefits now and in the future!    [ IGU for double glazed bifold windows. . . . ]

Convenient and comfortable in many ways, they are an essential part of insulating your home or office, for a more sustainable living experience.

The same high performance extends to acoustic insulation, with a potential reduction of 45dB in our casement, awning, tilt&turn and bifold range. The high-tech weather seal in combination with fusion welding of frames and sashes make the windows completely air and water tight - they have been tested to withstand even cyclone strength winds!   A complete guide for double glazed high performance can be found here
