31.5mm Walk-On Floor Glass Panel (Made to Measure)

Mid-range walk-on floor glass, cut to your size. At 31.5mm it steps up from our 25.5mm panel for medium-to-large spans and busier floors, supplied as glass only, ready to seat into your own opening or frame. If you would rather have the panel complete with a steel support frame, see our walk-on glass floor with steel framework.

Build and finish

• 31.5mm toughened and laminated glass: two 15mm toughened panels bonded together
• Polished edges as standard, with a 5mm radius to each corner
• Supplied as glass only; a steel support frame can be made to order if you need one

The extra thickness over 25.5mm lets it span wider openings and take heavier use. As always, the right thickness depends on the span, position, use and how the glass is supported, so check with a structural glass engineer for anything out of the ordinary.

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 band around the edge that hides where the glass seats, and any fixings or silicone, from above
• Ritec anti-condensation coating: an underside treatment that helps condensation run off rather than sit; it lessens condensation without curing it, so sort the source too

Other floor-glass thicknesses

For smaller openings, the same walk-on floor glass comes in 21.5mm and 25.5mm; for the largest spans and heaviest use, 33mm and 39mm. Our glass floor building regulations guide explains which thickness suits which span, and it stays the customer's job to confirm the glass meets their own building control sign-off.

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.

Made to order

Every 31.5mm panel is made to your size, usually inside about four weeks, and we arrange delivery once it is ready. For a cheaper off-the-shelf option, see our stock glass panels.

International delivery

We ship internationally. As panels are cut to order, we quote overseas carriage per job once we have the size and destination, crated to travel safely.

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.
