Whether you are an architect, specifier, contractor or self-builder looking to integrate abundant natural light into a residential or commercial property, it’s useful to know the most common skylight sizes that our customers request at Sunsquare.
Although most skylight manufacturers will allow their customers to view available rooflights from the smallest to largest possible dimensions, it’s good to get a feel of what the market generally looks for in the dimensions of skylight products.
Within this article, we’ll reveal the most popular rooflight sizes that we manufacture for Sunsquare clients and the typical lead time for stock-size skylights that can often be installed without the need for prior planning permission.
How do you know what size skylight you need?
If you want to know how big your skylight needs to be, you’ll need to calculate the prospective roof opening. Homeowners should seek guidance from their architect on measuring up for a new skylight, as you’ll need to take into consideration any external kerb or upstand – more on this later.
Fortunately, there are very few barriers as to what size your skylight can be. A new skylight does not require planning permission providing:
- The rooflight does not protrude more than 150 millimetres above the existing roof plane
- The rooflight is not higher than the highest part of the roof; nor does it stand above the roof ridge
It’s important that you choose a skylight size that offers enough natural daylight to flood into the interiors below. If you choose a product that is too small, your interiors won’t benefit from the full quota of natural light available. Choose a rooflight that’s too large and you’ll run the risk of overexposure to UV light. It’s a difficult balancing act, but one that your architect should be able to assist with.
How are skylights measured?
When you are deciding what size skylight you require, it’s important to note that skylights are not measured based on the size of the hole in your roof. Instead, they are measured based on the internal opening to the edge of the external upstand.
An upstand plays a key role in ensuring a skylight sits and fits well. Think of it as the framework that a skylight sits on, creating enough height from the roof surface and adequate pitch to allow for water run-off.
So, let’s say for example that you wanted to order one of our most common 24×24 skylight, the SkyView, this measurement reflects the external dimensions of the kerb or upstand, not the product itself.
What are the standard skylight sizes?
