Click together a wood terrace in an afternoon.

Garden tiles turn a concrete balcony or rooftop into a wood deck in an afternoon, with no fixings into the slab. The thermally modified slats resist rot and movement, and the grid base drains water away underneath.

Why specify thermowood tiles

A wood deck without building a deck

Each tile is a set of 13/16 in thermally modified slats fixed to a plastic grid base, about 20 x 20 in. Heat-and-steam treatment makes the slats resistant to rot, insects and warping without chemicals, so tiles can sit outdoors year-round on balconies, rooftops and terraces.
