All Kährs Bloc staves have an even timber grain, a lightly brushed surface and a beveled edge along all four sides. Nature Bloc has an oil prefinish, whilst White and Grey Bloc are oiled and stained, which creates an elegant washed hue. All Kährs finishes are solvent-free, exceptionally durable and promote easy care.

Individual staves are 15mm thick and measure 300x300mm, 300x600mm or 300x 900mm; the engineered construction comprises a sustainable oak surface layer and back, and a plywood core. This method provides a surface that is climatically stable, making Kährs Bloc Collection ideal for installation over underfloor heating systems.
