The internal quoted glass size is 1500 x 2500 mm, see the structural diagram below.

Safety and Compliance: Choosing the Right Skylight

When it comes to choosing a roof light for your home, we know that safety is an important deciding factor.

This product conforms to British Standards & Building Regulations and has all Safety Markings.

It is CE marked which is a certification mark that indicates conformity with the relevant EU directives and standards for products sold within Europe.

Our Skylights can be installed at a maximum pitch of 45 degrees.

Installation Specifications and Recommendations:

  • Internal Dimensions: It's important to note that the top pane of glass includes a black border, extending the external dimensions of the unit by 200 millimetres in each direction.
  • Creating the Opening: When preparing for installation, allow an additional 10 millimetres internally from upstand to upstand for proper fitting. For example, for a 600 by 900 unit, the opening should be 610 by 910 millimetres internally.
  • Upstand Construction: We recommend constructing the upstand (the wooden framework housing the skylight) using two-by-one or two-by-two-inch timbers.
  • Foam Rope and Sealant Use: For optimal installation, install foam rope on top of the internal supporting baton, which helps level out weight discrepancies and stress on the glass. We advise using Dowsil 791 black-coloured sealant to create a watertight perimeter around your upstand. Please note that acrylic sealants are not compatible with our units and should not be used.

When selecting sizes for our Skylights, please note that the listed dimensions correspond to the bottom (internal) glass panel.

This design ensures a robust, weather-resistant seal while maximizing the internal visibility and light entry of your skylight installation.

    The triple glazed skylight I got from Saris Extension for my flat roof is top notch. I love how it maintains the indoor temperature and the extra natural light it brings in is a treat.

  2. Joseph Robinson

    We’ve seen a significant rise in the value of our properties after installing these roof lights. They make each home feel brighter and more spacious, which has had a fantastic impact on resale values.

  3. Ethan McLeod

    The flat roof skylight has brightened up our entire Manchester home. The installation was smooth, and the results are amazing.

    The flat roof skylight is perfect for our home in Newcastle. It brings in lots of natural light, and the quality is fantastic.

  5. Chloe Baxter

    We added a flat roof skylight to our Liverpool extension, and it’s made such a difference. The room feels much bigger and brighter now.

  6. Wojciech Banach

    Our fixed roof window has made the attic more functional. The light is just perfect.
