Pitched Roof Skylight / Rooflight 600 x 900 mm

Our pitched roof skylights are manufactured to the highest standard making them frameless from the inside and out. They are easily installed with lead flashing, that’s cut on-site that is suitable for all roofs. As they are frameless internally they let in more light.

This high-performance, non-opening frameless skylight is triple glazed with 6mm toughened, self-cleaning glass and a U Value of only 0.9 W/m²K. The internal quoted glass size is 600 x 900 mm, see the structural diagram below.

When purchasing a pitched roof skylight for a tiled roof from us it is very simple.

All our skylights come triple-glazed as standard and have solar protection.

The upstand is formed with the same opening as you can see in our drawings.

All you need to add is the flashing of your choice in our accessories section.

The flashing is then wrapped around your upstand sealing the upstand to your roof tiles.

Make sure you have added the right amount of flashing, the full circumference of your skylight will require flashing.

Our rolls come in 7.5-meter lengths. Let’s say you have bought a 1000 x 2000mm skylight you then require a total of 6 meters as you have 2x 1 meter sides and 2x 2 meters becoming a total of six lineal meters therefore one roll of flashing will be required.

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.

    I can’t believe the difference these skylights have made in our home. They were easy to install and came in various sizes, so finding the right one was a breeze. The fast delivery and excellent customer support were the cherries on top. Our bedroom feels so much more spacious and airy now!
