02 / MADE TO MEASURE
Sized for your project
Square and rectangular formats suit different room layouts. Start with your internal kerb measurements and explore the proportions below.
03 / TWO-PIECE DESIGN
Designed for fitting
The PVC base and glazed top assembly form a two-piece system. Installation and kerb preparation must follow the current manufacturer’s guide.
INTERACTIVE DESIGNER
Make it yours.
Try three frame colours, compare clear and blue glass, and switch between exterior, plan and interior views. Your choices are carried into the enquiry form automatically.
DETAILS THAT MATTER
Choose the finish.
Confirm the fit.
Available in Grey RAL 7016, Black RAL 9005 and White RAL 9003, with clear/neutral or blue-tinted glazing. The thermally broken construction combines aluminium externals with a PVC frame.
The technical guide lists a 10-year guarantee, subject to the manufacturer’s terms. Ask us for the glass specification and whole-product thermal value appropriate to your size and installation.
Measure inside the kerb
Dimensions exclude plasterboard. Slope is the shorter side, from 500–1500 mm; spans extend to 2792 mm, subject to the manufacturer’s size matrix.
The guide specifies a 4° fall along the shorter side. At a 1500 mm slope, spans of 2500 mm and above are not listed as available. The designer flags larger combinations for a technical check.
The visualiser is a planning aid. It does not confirm structural suitability or create a manufacturing drawing.

YOUR QUESTIONS
Plan your skylight with confidence.
Is the glass size the same as my ordering size?
No. The ordering dimensions are measured to the inside face of the timber kerb, excluding plasterboard. Do not use the outside frame or glass size. Have your installer confirm the final measurements before ordering.
Can I fit several skylights together?
Yes, subject to your roof design. The manufacturer’s order form specifies at least 400 mm between flat skylights. The quantity control requests matching units; describe any different sizes in the project notes.
Can I walk on it, or install it over a pool?
This is not a walk-on skylight. Tell us if it will be above water or more than 5 metres above finished floor level, as the manufacturer calls for a laminated inner pane for those applications. Your installer should assess the glass specification and suitability for the intended location.
Does the quotation include installation?
This page is for supply-only enquiries. Your quotation will confirm the product, specification, price, delivery and included components. Installation, roof structure and kerb construction should be agreed separately with your installer.
How much will my skylight cost?
Pricing depends on the dimensions, glass, finish, quantity and delivery location. Send your design for a tailored quotation. The visualiser does not display estimated prices or take payment.
