High Performance Glass

Selecting a window or door that combines high performance glass with a quality frame and long-lasting weather resistant seals will result in a high performance, long lasting window and door.

Choosing The Right Glass

Accounting for up to 90% of the thermal performance of windows and doors, glass is the most influential factor in determining window and door energy efficiency. Not all glass products are created equal and it’s vital to select the appropriate glass for your specific purpose.

From self cleaning glass to glass that turns from transparent to opaque with the flick of a switch, today’s technology is so advanced that there are endless possibilities.

Decorative glass, whereby an image is encapsulated between two sheets of glass, means you can even choose to incorporate patterns or photos into your home’s design if you so desire. Glass is more than a building material; it offers endless aesthetic and practical benefits. Hopefully it will be part of your home for a long time so it is important to select glass that will meet your design and thermal performance requirements.


A range of coatings can be applied to glass to further enhance its properties.

Low E coatings (also known as spectrally selective coatings) lower the amount of heat flow through windows and doors, by reflecting radiation rather than absorbing it. A Low E coating can reflect unwanted heat in summer while retaining heat and preventing it from radiating out in winter.


Reflective coatings involve the application of a metallic film to one side of the glass in order to significantly increase the amount of reflected visible and infra red heat.


Tinted Glass

Tinted glass reduces outside glare, minimising fading to furnishings by UV rays and decreasing solar heat gain. Green, grey, bronze and blue are the most common tints, as they do not significantly alter the colour of the views through the window.

Double Glazing

Double glazed units (also known as Insulated Glass Units or IGUs) comprise two or more panes of glass, separated by an air (or gas) filled cavity that is completely sealed. IGUs provide thermal insulation and improved acoustic performance while also significantly improving a building’s energy efficiency.

A combination of IGUs and performance glazing can prevent up to 0% of heat loss in winter and 87% of heat gain in summer compared to standard mm single glazed windows.
