Both offering powder coated finishes to any standard RAL colour of your choice including dual colour your roof light can complement your room perfectly.

Different internal and external profile finishes are available including square, ornate and raked features to suit your application. Each roof light is made to your specific size with pitches ranging from 14 to 45 degrees, 30 degrees being the standard pitch. A range of glazing options from 24mm double glazed from 50mm triple glazed units are all available.

This means that Howells can provide even the most bespoke of roof designs.


What is a thermal break?

The thermally broken system is one of the more thermally efficient systems available on the market.

Both internal and external components are completely isolated from each other by means of either a polyamide strip, thermal barriers or insulation and isolators, so there are no cold bridges which reduces the temperature to a bare minimum.

With lower thermal U-Values in mind, our standard glazing material is 29mm double glazed units, with a centre pane value of 1.2. This U-value can be further reduced to an outstanding 0.7 by using a 50mm triple glazed option.
