The sizes listed are the external dimensions of your finished kerb upstand. The rooflight is designed to fit a kerb upstand of this size.
The Width dimension is the overall measurement to the kerb upstand directed across the fall of the roof. The Height dimension is the overall measurement of the kerb upstand running in the same direction as the fall of the roof.
Before measuring it is important to check that the walls to your upstand are parallel and square and that your upstand is finished and fully weathered.
Measure the overall finished kerb upstand across the fall of your roof, from outside edge to outside edge of the upstand. This will be your Width dimension.
Measure the overall finished kerb upstand in the same direction as the fall of your roof, from outside edge to outside edge of the upstand. This will be your Height dimension.

Rooflights including Aluminium rooflight are installed with a supporting upstand/kerb detail. Upstands are used to keep the glazed section of the rooflight off of the roof’s surface and are typically made of timber.
When ordering your Vision AGI rooflight(s) you will be offered the option of being supplied with our upstand. We would recommend that this be used as this will ensure that you have the correct size and pitch (to allow for water run-off) to your Upstand.
A good carpenter/builder can build an upstand with the required specification, either new or existing, as long as the following guidelines are adhered to:
- Ensure the upstand is square by measuring across the diagonally opposite corners.
- Allow for the correct pitch
- Minimum height of the upstand is 150mm
- Upstand width should be 100mm (including finishes)
Whether Vision AGI has supplied your upstand, or if you have constructed it yourself, it is important you instruct your roofer to correctly dress the upstand to ensure the correct fitting of your Vision AGI rooflight. Please ensure the roof membrane thickness does not exceed 8mm to the top most 100mm of the upstand and make sure that the top face of the upstand is free from undulations that exceed 3mm.
Current Building Regulations recommend that the upstand must protrude at least 150mm (at its lowest point) above the finished roof surface.
No, they can be installed in flat roofs as long as the upstand/kerb detail has a minimum 3 degree pitch to allow for water run-off. The Walk On Collection should have a 1 degree pitch.
Our standard glass specification is 32mm DGU toughened safety glass with low-e coating and warm edge spacer. The low-e coating allows the sun’s natural heat (solar gain) to pass through the panes then the low-e coating reflects the heat gain back into the room, which is more energy efficient. The warm edge spacer is made of an insulating plastic composite material that becomes a barrier to heat loss, keeping the edge of the unit warm, resulting in less heat loss. This is not the case with Walk-On Collection, as the glass specification is determined by the size & loading requirements.
However, you can add Solar Control Coating to reflect the sun’s radiation and help to reduce the build-up of heat in the room below. Solar Control Coatig can be specified for any of our Tailor Made or Bespoke rooflights.
All our electric rooflights run on 24V DC. We include the transformer and relevant components to operate your rooflight. The wiring diagrams needed will be sent with your rooflight (or may be found in the Technical area of our Resources page). They must be wired in and signed off by a qualified electrician for your insurance purposes.
The hinges on our rooflights are always on the width dimension (running across the fall of the roof).
Our rooflights come with a 1 year warranty as standard; you can extend this by going online and registering your details.
- Painted Surfaces – 10 years
- Glass – 10 years*

Please note: To maintain these warranties you will need to follow the instructions detailed in our Operation & Maintenance (O&M) Guide.
*Nickle Sulphide or any other inclusions in the glass that may cause a spontaneous breakage are not covered by the 10 year glass warranty. They are an extremely rare occurrence and not covered by any of the glass manufacturers, whether the glass is Heat Soak Tested following Thermal Toughening or not.
