A non-structural block of Hemp and Lime, Hempcrete blocks are primarily used as external wall insulation in timber framed buildings. They can be used in conjunction with any type of timber frame where they provide the insulation, the backing for plasters internally and the backing for renders externally.
They are particularly useful where exposing feature timber frames such as oak or glu-lam where they cloak the frame in a tea-cosy of insulation. The blocks and frame do not come into contact, instead the blocks are secured up to 25mm off the frame with stainless steel wall ties, the entire frame therefore is exposed internally and no cutting of blocks is required resulting in quick build times.
Hempcrete blocks are lightweight and laid in thin bed lime mortar making them easy and quick to lay.
