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.
