About Spectrum Skylights

Are Spectrum Skylights thermally broken?

Due to the fact our skylights are fully welded to increase their strength and durability they do not feature a traditional thermal break (a polyamide plastic segment which divides the inner and outer frames).

However they do feature a large high performance thermal barrier between the external frame and the inside of your property. This effectively prevents thermal bridging between the inside and out but provides an incredibly strong and durable skylight.

Alongside this, the limited plastic content of our product enables easier recycling at the end of the skylights life as well as a lower demand for oil based products reducing our environmental impact.

Do you have technical drawings of your skylights?

These can be found within our ‘downloads’ section.

Do you supply self-cleaning glass?

‘Self-cleaning’ glass is a bit of a myth as all glass will require intermittent maintenance. However we do offer a low maintenance coating on all of our skylights which can drastically extend the intervals which your glass will require cleaning.

Do you supply toughened safety glass?

All of our skylights are fitted with toughened safety glass as standard.
Our security range also features a laminated inner pane for additional security and safety.

How large can a skylight be without framework?

Unfortunately at present we do not supply frameless skylights.
However we do offer our flat skylights in sizes up to 3m x 1.25m with no visible frame work when viewed from the inside of the property.

How much will my skylight weigh?

This will vary depending on the size; however a weight is quoted on the page for all stock size skylights and is generated dependant on size on our bespoke quote generator.

If you are in doubt, please contact a member of our sales team.

What colours can I choose for the paintwork?

Our skylights are offered in 3 standard colours, RAL 7016 – Anthracite grey, RAL 9016 – Traffic White and RAL 9005 – Jet Black.

Generally our Pyramid Skylights are coated RAL 7016 Externally and RAL 9016 Internally to provide a clean unobtrosive internal view.

However, we are able to produce skylights in almost any standard RAL colour upon request but please note alternative colours will have an increased lead time on standard products. Please contact a member of our sales team for additional information.

What is the largest size skylight that you can supply?

Our largest standard Flat Glazed Skylight is 3m x 1.25m, however we do offer a modular system which can be extended.

Our largest Pyramid Skylight is 3m x 2m, one of the largest available on the market.

Preparing for your Spectrum Skylight and Installation

Are the roof pitches for the Flat Glazed & Pyramid Skylights fixed?

Our Flat Glazed Skylights can be installed on roofs with a pitch from 0 degrees through to roof with pitches up to 45 degrees. However, on roofs with a pitch of less than 5 degrees the upstand must provide a 5 degree fall.

Our Pyramid Skylights can be installed on a level upstand.

Please see our ‘upstand construction manual’ for more detailed information.

Can a Spectrum Skylight be fitted to any roof?


On all roofs there will need to be an upstand constructed which is a minimum of 150mm above the roof finishes.

On flat roof installations your upstand for Flat Glazed Skylights must provide a minimum of 5 degrees pitch to allow for water run off.

The only other limitation is that the pitch of the skylight cannot be greater than 45 degrees.

Please see our ‘upstand construction manuals‘ for additional information.

Can I use my own upstand?

Of course you can!

However please ensure it matches our specifications which can be found in our ‘upstand construction manual’.
If you do not construction in line with this you may suffer with ponding on your glass. Worse still, it may not fit your upstand.

Can you do a site survey?

A site survey is available at an additional cost however this may increase the lead time for your skylight as we will have to schedule in the survey before we are able to begin production.

Do I need planning permission to install a skylight?

Generally you do not require planning permission to install a skylight into an existing building; however we recommend checking with your local planning department prior to starting any works.

Do you install the skylights?

We do offer an installation service at an additional cost; however the skylights are incredibly simple to install and come with a comprehensive installation manual.

Do you supply upstands?

Upstands can be supplied at an additional cost. This does however guarantee a perfect fit!

How high does the upstand need to be from the surface?

The minimum height of upstand is 150mm from the weathered surface of the roof.
