Grey tiles

Grey is the least uniform group on the site. Matt, gloss, rough textured, polished and soft polished faces all appear, across formats that run from 20 × 145 mm strips up to 600 × 1200 mm. Some record a class in the supplier's current documentation and some have nothing on file. We do not hold the underlying test reports.

A recorded class is a reference value, not approval for a particular application. Confirm the required specification for your project with the responsible installer or specifier.
