Being established for over 30 years, Aspect Windows are fully versed in all aspects of glazing from traditional to modern, specialising in high performance attractive glazing systems. With a combined knowledge of over 100 years we can assist you to realise your project.

Our rooflights are constructed from aluminium, and are fully thermally broken giving superior thermal efficiency coupled with low maintenance and stylish design.

We offer quality powder coated finishes to any standard RAL colour of your choice including dual colour (i.e. internal/external different colours).

Different internal and external profile finishes are available including square, ornate and raked features to suit your application.

Our rooflights are made to your specific size with pitches ranging from 15 to 45 degrees (30 degrees is our standard). Rooflights can accommodate a multitude of glazing options from 24mm double glazed to 50mm triple glazed units.

What Does Thermally Broken Mean?

Our system is one of the most thermally efficient systems available on the market.

Both internal and external components are completely isolated from each other by means of; polyamide strip, thermal barriers, insulation and isolators, so there are no cold bridges, thus reducing temperature transfer to a bare minimum.

Another key feature bespoke to our system is that both the glass and glazing bar system does not project outside our eaves beam, i.e. reducing a cold bridge even further.

Designing a roof to lower U values even further is achieved by maximizing glass area (maximum glass to aluminium ratio), i.e. the least amount of glazing bars possible.

With lower thermal U values in mind our standard glazing material is 28mm double glazed units, with a centre pane U value of 1.2 W/m2. This U value can be further reduced to an outstanding 0.7 W/m2 by using 50mm triple glazed option (dependant on roof style).


There’s an abundance of different glass specifications to choose from.

Our standard specification for glass is 28mm Clear toughened double glazed units (with a centre pane U value of 1.2 W/m).

However, we do offer a 50mm triple-glazed unit option (with a centre pane U value of 0.7 w/m2)

Glass upgrades such as Activ Self Cleaning and also Activ Blue or Neutral (Grey) Solar controlled options are available just to name a few.
