Roof Lanterns & Rooflights
A made-to-measure flat rooflight with a walk-on glass specification for terraces, roof decks and other usable roof areas.
Overview
The Maxi-Walkon is the walk-on specification within the low-profile Maxi-Flat rooflight family. It is intended for roof terraces, decks and other usable roof areas where the surface above must remain accessible while the room below receives natural light. The glass is not treated as a standard rooflight pane: its laminated safety build-up, anti-slip finish, loading requirement, perimeter support, finished levels, drainage and lifting route are confirmed together. Cii surveys the actual opening and surrounding terrace construction before a written quote or manufacturing approval is issued.
Walk-on specification available within the supplier's Maxi-Flat rooflight range
Laminated safety glass build-up specified for the intended foot-traffic use
Anti-slip surface treatment agreed as part of the measured specification
Opening size, loading, perimeter support and finished levels checked on survey
Drainage, weathering and lifting access reviewed before manufacture
Low-profile single-panel form keeps the daylight opening clear from below

Walk-On Specification
A walk-on rooflight has to work as part of the terrace above and as a clean daylight opening for the room below. Glass, support, drainage and finished levels are therefore specified together.
The walk-on route uses the low-profile Maxi-Flat form with a project-specific glass and support specification. We measure the opening first, then coordinate it with the terrace above and the room below.
The studio view shows the slim aluminium perimeter and single glazed opening. The finished terrace detail is designed around this form rather than treated like a raised roof window.
The rooflight is planned with the surrounding paving or deck, perimeter support, falls and drainage so the finished walking surface reads as one coordinated detail.
From inside, the walk-on rooflight still performs as a low-profile overhead light source. The ceiling reveal and internal finish are included in the survey discussion.
These conservative Maxi-Flat family guide dimensions show the smaller and larger measurement anchors for the Walkon discussion. The walk-on price remains survey-led because the glass loading, support and terrace detail change the final specification.
Walk-on glass and support priced after survey

Final figure follows the approved walk-on specification
The larger reference point in the current Maxi-Flat pricing sheet. The intended loading, glass handling and perimeter support must be confirmed before this is treated as an available Walkon size.
The 500 x 500mm and 1200 x 2000mm points give us the current guide range to discuss. The rooflight is manufactured around the measured opening rather than selected from a stock-size list.
For a walk-on unit, we also have to approve the glass loading, anti-slip finish, perimeter support, finished terrace level and lifting route before confirming the available size.
Send us the opening dimensions and a photograph of the terrace area. We will confirm the specification and provide the complete written price after survey.
Send us your size for a full quoteThe standard Maxi-Flat sheet lists from prices of £1,399 and £1,899 at these guide sizes, but those figures are not published here as Maxi-Walkon prices. Walk-on glass, structural support, terrace integration and access are quoted separately after survey.
The supplier literature confirms that a walk-on option is available within the Maxi-Flat range. The complete glass build-up, surface treatment and support detail remain project-specific. Five RAL frame colours are stocked, with other RAL finishes available to order.
The glass is specified for the intended foot-traffic use, with laminated safety construction and an anti-slip surface route agreed before manufacture. We do not substitute standard roof glass.
We inspect the perimeter support, roof build-up, finished floor level, falls and drainage. Any required preparation is identified before the rooflight is released for manufacture.
The aluminium finish, clear or privacy glass requirement and any compatible glare-control route are considered alongside the structural specification, not added as an afterthought.
The final price follows the measured width and length, glass loading and finish, perimeter support, terrace build-up and access route.
Drainage, weathering, lifting and any preparation or making-good work also affect the installation scope.
Send the approximate opening size and a photograph of the terrace area if you already have them. We will still verify the detail on survey before confirming the specification.
Send us your terrace detailsA standard flat rooflight is not automatically safe to walk on. Only use the unit for foot traffic when the written specification confirms the walk-on glass and support detail.
Product fit
Maxi-Walkon is the walk-on specification within the low-profile Maxi-Flat family. The opening, laminated glass build-up, anti-slip surface, perimeter support, finished level and drainage detail are planned together so the terrace remains usable while the room below still receives light.
Optional Upgrade
Walk-on rooflights are structural first, so blind compatibility has to be treated carefully. Where privacy, glare, or overlooking is part of the brief, we can discuss integrated blind options only if they suit the walk-on glass specification and support detail.
A privacy and glare-control discussion for walk-on glazing, not an automatic add-on.
Integrated rooflight blinds
Rooflight-specific blinds are planned with the overhead glazing, kerb, and control route.
Electric control
Remote operation is normally the practical route for roof glazing that cannot be reached by hand.
Structural glass, anti-slip finish, support detail, and access come first. If integral blinds are not compatible, we will discuss privacy glass or other shading routes instead.

Step 1
We measure the opening and check the intended use, perimeter support, terrace build-up, finished levels, falls, drainage, weathering, lifting route and the internal reveal below.
Step 2
The opening size, laminated glass build-up, anti-slip surface, frame finish and any preparation work are recorded together. The final lead time is confirmed on the written quote before manufacture.
Step 3
Our Cii team installs the made-to-measure unit to the approved support detail, completes the perimeter weathering and checks the finished levels, drainage and glass condition before handover and guarantee sign-off.

Send us the approximate opening size and a photograph of the terrace area if you have them. We will survey the support, finished levels, falls, drainage and access, then confirm the walk-on glass and installation specification in a complete written quote.
“Roof lantern fitted over our orangery. The light it brings in is incredible. The installation team were excellent and left the site spotless. Highly recommend Cii.”
“Cii fitted our roof lantern on the rear extension. Excellent craftsmanship, very professional team, and the room is transformed. Highly recommended.”
“Outstanding from start to finish. The casement windows are a perfect fit and the energy difference is already noticeable. The lads were tidy, efficient, and clearly knew their trade.”
