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.

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

    Choosing Saris Extension for our triple glazed skylight was the best decision we made during our townhouse renovation in London. The self-cleaning glass is a lifesaver! We couldn’t be happier with the result.
