Structural glass for foot traffic
Toughened laminated glass is load-rated and supplied with an anti-slip surface, so the terrace above remains safe and fully usable.

Roof Lanterns
A structural walk-on rooflight supplied and fitted in Essex for terraces, decks, and usable flat roof areas.
Technical Details
Product fit
A walkable rooflight is a structural product, not a standard rooflight with stronger glass. It needs the right opening, support, finish level, drainage detail, and anti-slip glass specification 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.

The Maxi-Walkon Rooflight is the structural glazing solution for Essex flat roofs that form part of a walkable terrace or deck. Toughened laminated glass is rated for foot traffic and supplied with an anti-slip surface treatment as standard, allowing the rooflight to sit flush within the terrace surface without restricting movement. The room below gets a clean overhead light source while the terrace above remains fully accessible. We survey support, finished floor levels, drainage, surrounding build-up, access, and glass finish before confirming whether a walk-on specification is suitable.

Walkable Rooflight
The Maxi-Walkon lets you use the roof above and bring natural light into the room below, without choosing between the two.

Toughened laminated glass is load-rated and supplied with an anti-slip surface, so the terrace above remains safe and fully usable.

The slim frame profile allows the rooflight to sit flush within the terrace surface, so foot traffic flows naturally across the deck.

The room below benefits from a clean natural light source overhead without any visible structure obstructing the view upward.

Built to your exact terrace opening on the same 5-day express manufacturing service as the rest of the Maxi range.
