*Please note width and length dimensions are always defined as to the external face of the timber kerb that Ultrasky products sit on (not supplied and recommended to be 150mm high x 70mm wide)
Our Lanterns are designed to fit on a timber kerb installed inside the roof. This is usually 150mm high x 70mm wide.
The set-out dimensions of our roof lanterns are measured to the external wall of the timber kerb and NOT the size of the cut-out in the flat roof.
In most cases therefore the dimensions of the lantern are calculated as follows:
Length = Length of hole + (2 x Kerb Width)
Width = Width of hole + (2 x Kerb Width)
Hole 1000mm x 1500mm
Kerb Width 70mm
Overall Dimensions of Lantern: 1140mm x 1640mm
We can offer any size of roof lantern you require so you can either choose the size of lantern first and then cut out the hole in the roof to fit or you can order bespoke sizes to fit the hole.
For full installation instructions download the detailed Installation Guide.
Select the custom size that you require either from the presets or using the bespoke design tool. Depending on the size parameters that you select, the price for your bespoke roof lantern will immediately be displayed.
We can usually deliver our Skylights within 6 working days directly to site for a standard size and colour. For Skylights with coloured internal claddings, the delivery time could be longer.
To ensure that the roof lantern arrives in perfect condition the frame and glass are delivered separately and will require assembly.
Skylights cannot be collected from our factory but can be delivered to a different location if you require.
We will charge £75 for delivery of all items required for the installation, to UK mainland addresses. There may be an additional delivery charge based on non-mainland UK locations. In the event that your order incurs additional charges, you will be contacted by our Customer Service Team at the point your order is being processed.
Ultrasky Lanterns are covered by a 10-year guarantee from date of delivery against discolouration, cracking, shape deterioration and component failure. Please note that the glazing bars and aluminum frames are not covered if they have been subject to aggressive chemical cleaning of any sort. Aluminum sections are guaranteed against bending, cracking and breakage under normal use, within normal environments. Installation, sealing and waterproofing are not covered by the guarantee and are the responsibility of the installer or roofer. Guarantee is void if units have been damaged by the installer using incorrect sealant type (normal silicone sealants damage the special outer coating) or through cleaning with harsh chemicals.
Conservaglass sealed glazing units carry a 10 year unit seal warranty from date of delivery. If a unit seal should fail within the 10-year period, it will be replaced free of charge, provided that:

Installing an Ultrasky roof lantern is a simple process for an experienced installer. Some customers with building or glazing experience prefer to install themselves, but we’d only recommend this if you are 100% confident.

Summertime in Britain is a wonderful thing. For a few short months, we’re living like Australians, grilling on the barbeque in our shorts and soaking up the rays.
