EXPLORE YOUR DESIGN
Your lantern. From every angle.
Change the dimensions, frame finish and glass tint. Rotate the lantern, check the top view or look up from below. Save your design or open an enquiry email with your choices already included.
The designer is a visual guide, not a manufacturing drawing or instant quotation. Colours, glazing divisions and available combinations must be confirmed against the final Ultrasky specification.

Make the finish your own
Explore white, grey or black frame finishes, with internal colour choices. Glass options include clear, blue, aqua, brown and neutral; confirm the combination in your quote.
03
Supplied for assembly
The frame and glass are supplied separately for assembly on site. Your builder or installer prepares the supporting kerb and completes fitting and weatherproofing.
MEASURING YOUR LANTERN
Measure the kerb, not just the hole.
Ultrasky ordering dimensions are measured to the outside faces of the timber kerb. They are not the clear opening in the flat roof. A typical kerb is 150mm high and 70mm wide, subject to the installation specification.
For example, a 1,000 × 1,500mm opening with a 70mm-wide kerb on each side gives external dimensions of 1,140 × 1,640mm.
Have your installer check the opening, kerb construction, roof build-up and final order dimensions before manufacture.

Your installation
Supply only means installation labour is not included. Arrange the roof structure, kerb, waterproofing, lifting equipment, access and internal finishing with your own installer.

BEFORE YOU ORDER
Ultrasky roof lantern questions.
Can homeowners buy a supply-only lantern?
Yes. We welcome enquiries from homeowners, competent DIYers, builders and conservatory companies. You remain responsible for arranging suitable installation and confirming the survey dimensions.
Is this a complete flat roof or conservatory roof?
No. This page is for the roof lantern itself. The surrounding flat roof, supporting structure, kerb and waterproofing are separate works. For a complete conservatory roof kit, explore our Classic, Ultraroof or Livinroof pages.
Can I choose how many glazing bars it has?
The designer lets you explore different visual layouts. The manufacturer must approve the actual bar arrangement for your dimensions and specification. Treat your saved design as a starting point for the quote.
Which glass should I choose?
Consider solar control, insulation, orientation and the use of the room, as well as the tint. Glass appearance in the designer is illustrative. Ask us to confirm the performance and safety specification of the glass included in your quotation.
How do I get a price for my design?
Choose your options above and select “Enquire about this design”. It opens your email app with the design details. Add your quantity, postcode and contact details before sending. Alternatively, save the summary and email hello@conservatoryroofshop.co.uk.
