What is a Timber Upstand &
How Can I Build One?
If you are adding a skylight to a flat roof, you must decide on whether to construct your own upstand or purchase one from your rooflight supplier. Here you can find some helpful infomation to help you make your decision.
The job of an upstand (sometimes referred to as a Kerb) is to lift the glass element of your rooflight off of the roof’s surface, and is required by building regulations for safety and weathering reasons.
Should I make my Own?
Cost is generally the main reason people choose to make their own. A simple upstand can be constructed from excess timber on site minimising waste or using standard timbers found at any local wood supplier.
A more advanced detail is the equivalent of creating a mini stud wall. The purpose of this is being able to insulate the inner cavity which gives greater thermal performance and sound insulation.
How do I build my own Upstand?
If you are looking to build your own upstand for one of our stock skylights you can see the process below. When creating your upstand make sure the width is correct size for your rooflight as these can very from 60mm to 100mm depending on the system you order.
Please Note – If you select a lantern rooflight you do not need to add a pitch to your upstand.
Choosing a Pre-Made Upstand
Whlie a pre-made insulated upstand can be a little more expensive a purpose manufactured version has numerous benefits including improved thermal performance, weathering and air tightness. The frame has been designed and engineered to fit your exact rooflight giving you peace of mind that your skylight is going to fit perfectly.
