⚠️ Important Notice

Some suppliers cut costs by using thin glass in large rooflights — this can cause sagging and water pooling.
Our tests show that reinforced, thicker glass is essential for safety and durability.

At Saris-Extensions, every rooflight is built to UK standards, ensuring lasting strength and peace of mind.

    SPECIFICATIONS

    Pitched Roof Skylight / Rooflight 1000 x 2000 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 1000 x 2000 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.

    INSTALLATION GUIDE

    Step-by-step Installation Guide

    Over the years, we've observed numerous errors and poor practices in skylight installations that have led to persistent issues. To help you avoid these pitfalls, we're eager to share our accumulated expertise and knowledge. We highly recommend checking our detailed installation materials to ensure you apply the best practices for a flawless and durable installation.

     

    Structural opening – provided By builder

    When selecting sizes for our Skylights, please note that the listed dimensions correspond to the bottom (internal) glass panel. Each skylight's top panel extends an additional 100mm on each side, making the overall externally visible size 200mm larger in both width and length. This design ensures a robust, weather-resistant seal while maximizing the internal visibility and light entry of your skylight installation.
