Hempclay Blocks

Hempclay Blocks

Natural Building Blocks

A non-structural block of Hemp and clay, Hempclay blocks are primarily used for the construction of internal walls and as the external wall insulation in timber framed buildings. They can be used in conjunction with any type of timber frame where they provide the insulation and the backing for plasters.

Hempclay blocks are lightweight and laid in thin bed lime mortar making them easy and quick to lay.
