Product Description

FIBOLITE is an ultra-lightweight loadbearing block manufactured using Plasmor’s own expanded clay technology. This advanced process transforms geochemically specific clay into lightweight nodules with a vitrified outer shell and a honeycombed, air-filled core—providing superior strength without the weight.
Ideal for new builds, extensions, renovations, and repairs, FIBOLITE blocks are easy to handle, thermally efficient, and versatile enough for a wide range of internal and external wall applications. Their textured surface also provides an excellent key for plastering or rendering.
