Walk on glass floor for homes and businesses in Catford
Walk-on glass panels are laminated from several layers of toughened or heat-strengthened glass so the panel stays in place even if one layer breaks. The top layer usually carries an anti-slip finish, such as a fritted or etched pattern, and the panel thickness is calculated for the expected loads.
A structural glass roof replaces most or all of a roof with large glass units carried on glass beams, slim steel or aluminium supports. Side-return extensions often use a single run of glass from the house wall to the boundary, giving a bright kitchen without the ridge and bars of a framed roof lantern.
In England, Approved Document L limits how much of an extension can be glazed when the simple standard route is used. Large glass roofs often go beyond that limit, so energy calculations are usually needed to show the extension still complies, and building control checks them.
The price of a glass roof or walk-on panel depends on glass size and make-up, the number of laminated layers, coatings, support beams or framing, structural design, lifting equipment and access. Bespoke shapes and very large panels cost more. See the guide prices for typical ranges.

Working in Catford
- Postcodes covered
- SE6, SE13, SE4 and the surrounding area, including Lewisham, Blackheath and Greenwich
- Coast
- Catford is well inland, around 27 km from the nearest coast, so salt exposure is not usually a factor.
- Daylight and sun
- In Catford the midwinter sun reaches about 15° above the horizon at noon, with roughly 7.6 hours of daylight, rising to about 62° and 16.4 hours in midsummer. Overhead glass admits far more daylight than vertical glazing, especially in summer when the sun is high. South-facing glass roofs usually need solar-control coatings or fritting, while north-facing roofs can use clearer low-E glass to maximise winter light.
- Access and setting
- Rural sites may have long or narrow access tracks that limit crane positions and panel sizes, so access is surveyed early. Exposed locations face higher wind and snow loads, and leaves and debris from nearby trees mean gutters need regular clearing.
- Rules in England
- Approved Document K requires safety glass in critical locations in England: glazing in doors and in side panels within 300 mm of a door, up to 1500 mm above floor level, and any glazing in walls or partitions up to 800 mm above floor level.

If the glass sits in a fire-resisting door or screen, such as a flat entrance door or a commercial corridor screen, it must be replaced with fire-rated glazing tested as part of that system. Ordinary toughened glass is not a substitute.
Choosing your glass roofs
Glass floor panel
Laminated glass floor sections that let light through to a basement or lower floor, supported on a level, engineered frame.
Walk-on rooflight
A multi-layer laminated glass panel set into a roof terrace or flat roof, with an anti-slip surface for foot traffic.
Solar-control coatings
Coatings or fritted patterns that reduce heat gain and glare under overhead glass on sunny elevations.
Glass Roofs in Catford: questions
How is a glass roof installed?
A glass roof is installed onto supports already built and checked, such as walls, steel beams, glass beams or upstands. The glass units are lifted with a crane, glass robot or vacuum lifters, set onto gaskets or setting blocks, fixed and then weather sealed. Most domestic roofs are installed in a day or two once supports are ready.
Does a glass roof need building regulations approval?
Yes. A new glass roof, frameless rooflight or walk-on panel is building work that normally needs approval through building control, covering structure, energy performance and fire performance near a boundary. Highly glazed extensions often need energy calculations to show compliance. The rules differ between England, Wales, Scotland and Northern Ireland, and we explain the route for your project.
What guarantee comes with a glass roof?
Manufacturer guarantees apply to the glass units, coatings and any framing or fixings, and the terms are confirmed in writing. Supports built by others are covered by their own builder's terms. Guarantee terms for our installation are set out in writing with your quote, so you know what is covered and who is responsible before work begins.
How much does a glass roof cost?
The cost of a glass roof depends on the area of glass, the size of each unit, the glass make-up and coatings, the support beams or framing, the structural design and the access for lifting. Walk-on and very large panes cost more because of their thickness. See the guide prices for typical ranges; the written quote fixes the price.
