Gemini Twintile®

Gemini TwinTile is an interlocking tile which is 270mm x 330mm overall. With its carefully judged central groove, the tile gives the appearance of two plain tiles side by side when laid. With a laid weight of just 50kg per metre square it is equally as cost effective for refurbishment as for a new build.
