25.5mm Walk-On Floor Glass Panel (Made to Measure)

Structural walk-on floor glass, cut to your size. This is our 25.5mm toughened and laminated panel, supplied as glass only, ready to seat into your own opening or frame. If you need the panel complete with a steel support frame, see our walk-on glass floor with steel framework.

Build and finish

• 25.5mm toughened and laminated glass: two 12mm toughened panels bonded together
• All edges polished as standard, with a 5mm radius to each corner
• Glass only; a steel support frame can be made to order (ask us)

Non-slip finishes

Non-slip is an optional extra, and we would strongly advise taking it. Glass is inherently slippery underfoot, and the only case where we would tell you not to bother is a panel tucked away in a corner that is unlikely to be walked on. There are two ways to do it and they suit different situations.

Invisible non-slip coating — what we strongly advise for internal floors. A clear chemical treatment that makes no visible difference to the glass whatsoever, which is the question almost everybody asks before they order. You keep the clarity and the view straight through the panel. It reaches a Pendulum Test Value (PTV) of 68, against the 36 needed to count as low slip risk in the dry, and lasts around five years before it wants redoing.

Checkerplate top layer — for glass that gets wet. A raised, sandblasted checkerplate texture on the top panel, and the highest grip option we offer. The trade-off is worth being straight about: it visibly obscures the glass. Where the panel is there to bring daylight into the space below, that is usually no problem at all. Where it is there to be looked through, it changes the thing you bought it for.

So: internal and dry, the invisible coating and you would never know it was on there. Wet, or outside where it will be rained on, checkerplate is the safer answer.

Border and condensation options

• Back-painted border: a painted edge to hide the seated edge of the glass and any silicone or adhesive
• Ritec anti-condensation coating: applied to the underside, it helps condensation run off; it reduces rather than stops condensation, so treat the cause too

Choosing a floor glass thickness

Floor glass is sized on the panel, not on a rule of thumb, and the honest position is that we would rather size it with you than have you guess. As a broad steer:

• 25.5mm — domestic, smaller spans. Suits panels up to around 1000mm in one direction: a long narrow panel such as 3000 x 1000mm is fine, whereas 1000 x 1010mm is not. In most applications we advise 25.5mm up to about 1000 x 1000mm, and above that considering a thicker panel even where 25.5mm technically works.
• 31.5mm and 33mm — larger spans and busier floors. These two are extremely similar in performance. 33mm is often specified because it is built from three layers rather than two, which gives an additional level of protection, and that is usually the reason people choose it over 31.5mm. Our practical ceiling in either is around 2000 x 1500mm, and we stop there deliberately — past that size the limit is not really the glass, it is weight and what can sensibly be delivered and lifted into place.
• 39mm — generally a commercial floor thickness.

Send us the opening size, how the panel will be supported and what will be walking on it, and we will tell you what we would supply. Getting this right at quote stage costs nothing; getting it wrong costs a panel.

Need a different thickness?

Bigger spans need thicker glass. We make the same walk-on floor glass in 21.5mm, 31.5mm, 33mm and 39mm. The right thickness depends on the size, location, building use and how the glass is supported. Our glass floor building regulations guide explains when each applies, and it remains the customer's responsibility to confirm the glass meets their own building control requirements (a structural glass engineer can advise on anything unusual).

Made to order

All panels are made to order, usually ready in about 4 weeks. Once you order, the glass goes into production and our team arranges delivery when it is ready. On a budget, also check our stock glass panels.

International delivery

We ship worldwide. As each panel is cut to size, overseas delivery is quoted per order: send us your sizes and delivery address and we will price suitable crating and freight.

A note on specification

The guidance on this page reflects what we typically supply for jobs of this kind and is offered in good faith to help you order the right thing. It is not a structural specification and it is not a substitute for project-specific design. Walk-on glass is a structural element: spans, support conditions, edge bearing, imposed loads, point loads and use all vary from site to site, and suitability for your particular opening remains the responsibility of you, your designer, your structural engineer or your building control body. We manufacture and supply to the sizes and specification you give us. If you are in any doubt, send us the details before ordering, or have them confirmed by your engineer.
