Structural glass flooring — whether etched, sand-blasted, or deliberately textured — is an increasingly common feature in UK retail, hospitality, and commercial architecture. Slip testing is essential because visual appearance is a poor guide to slip performance.
Glass flooring gets its slip resistance from surface texture — either chemically etched, sand-blasted, or ceramic-frit pattern applied. The texture pattern is the entire basis of slip performance. Different etching or blasting patterns produce dramatically different PTV values.
Glass floor wet performance depends heavily on the texture depth. Shallow decorative etching might perform well dry and poorly wet; deep texturing performs better in contamination. PTV testing in wet conditions is essential.
Highly polished non-glass surfaces — polished porcelain, polished concrete, high-gloss resin — share similar characteristics. Specification without testing is a common source of commercial slip claims.
It depends entirely on the etch depth and pattern. Shallow decorative etching often has poor wet PTV; deep texturing performs much better.
Yes — we test structural glass floors using BS 7976 / BS EN 16165 in both dry and wet conditions.
Similar challenges — high-gloss surfaces typically have excellent dry PTV and poor wet PTV. Specification without testing is a common cause of commercial claims.
