The slabs are 455mm wide & are rigid or semi-rigid, these suit standard vertical wall tie spacings which provide a closed ‘knit’ joint with adjacent slabs.
In addition to an excellent thermal performance these also have some additional benefits that can often be forgotten about, such as; not sustaining vermin nor encourage the growth of bacteria, fungi or mould.
