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.

  1. Dean Jones

    Living in Newcastle, I wasn’t expecting the skylight to arrive quickly. But Saris Extension surpassed my expectations. The nationwide delivery was so fast, and the skylight was installed before I knew it. Now, I can’t imagine my home without it. Kudos to Saris Extension!

  2. John Williams

    We recently renovated our London flat and wanted to add a skylight for more natural light. Saris Extension exceeded our expectations. The entire process from the consultation to the installation was seamless. Our home is now filled with natural light, even on the greyest London days!

  3. Roger Cox

    I am impressed with how quickly my triple glazed skylight 500 x 3000 was delivered. The quality is top-notch and the fast shipping made the whole process even smoother

    The flat roof triple glazed skylight from Saris Extension has been a game changer. The energy efficiency is impressive and the natural light it brings in is simply sublime.

  5. Edward Murphy

    Having used these roof windows on several projects, I can attest to their longevity and lasting charm. They still look as good as new and function flawlessly even after two years. Our clients couldn’t be happier!

  6. Thomas Hughes

    We’ve seen a remarkable increase in the resale value of our properties after installing these roof windows. They not only improve the aesthetics of our homes but also attract potential buyers.

    I needed the 500 x 3000 skylight by Monday and they delivered it on time! I would recommend Saris extensions for their quality products and impeccable customer service.
