Triple glazed skylight


The glass makes the difference

When it comes to rooflights, the glass you choose can make a huge difference to the performance of your product. 

Glass will typically make up 70% of your rooflight, and it's at the heart of controlling the flow of natural light, the level of safety and security, and of heat retention. It can even help protect furniture against fading.

Stella and Planitherm glass

Stella rooflights use the highest performance Comfort Plus glazing units from Planitherm. These modern high tech glazing units maximise comfort, for a difference you may not 'see' but will certainly feel.


Whether you’re looking for warmth, a peaceful night’s sleep or to enjoy a sun-filled room without overheating, Planitherm units offer the ultimate high-performance glass for every application.

It's the UK's leading energy-efficient glass and can be incorporated into any style of rooflight.

A wide range of rooflight glazing options for every application

We offer a wide range of glazing options for our bespoke rooflights and skylights.  Typically our focus is on thermal performance and self-cleaning.  If however you have a requirement for improved sound efficiency, fire, safety or shading then we will have a range of options available for you.

There are a number of factors that you should consider when designing your rooflights and probably the most important is to specify the right glass for the application in which it is being used. 


This means that the type and thickness of the rooflight glazing also needs careful consideration. For example, the larger the glass area then the thicker the units will be.  


Toughened or laminated glass?

The positioning of the rooflight will also determine what type of glass should be used in the unit make up.  For example, our double and triple glazed rooflight units would normally be produced using toughened safety glass but if your rooflights are being fitted at a height of 5mts or more above floor level, then the inner pane should be laminated glass. 


Likewise, if you are using large areas of glass at lower levels you should consider what is going to be underneath and undertake a risk assessment to decide whether having a laminated inner pane is a better option.

If laminated glass is viewed as even safer than toughened, you may wonder why we wouldn’t include that in our units as standard. Choosing your rooflight glass unit specification is as important as the frame itself and needs careful consideration.  


Not all glass options are suitable for all applications and we would always advise that you discuss your project with us. We have written a helpful article on the practicalities involved is specifying large rooflights and you can read by clicking here.
