Featured Products
Gutex, based in Germany, is a fourth generation family run company and leading manufacturer of woodfibre insulation boards. Gutex was the first in Europe to manufacture insulation boards from ecological wood fibre, incredibly this was in 1932. Testament to Gutex's continuous innovation philosophy, they became the first manufacture to produce single-ply homogeneous wood fibreboard insulation using a low-energy dry process which allowed the production of thicker higher quality boards, providing superior thermal storage capacity.
Diathonite Thermactive is a breathable lime and cork-based insulating plaster designed for internal solid masonry walls and ceilings. It improves thermal performance while allowing moisture to move naturally through the wall, helping to reduce condensation and maintain a healthier indoor environment, making it particularly well suited to older, solid-wall and retrofit properties.
Lime Green Solo is a breathable, one-coat lime finishing plaster for internal walls and ceilings, designed to provide a smooth, durable finish over masonry, lime plasters and wood fibre insulation boards. Made from natural lime-based materials and free from cement, it helps regulate moisture, reduces the risk of condensation and mould, and is particularly well suited to the renovation and retrofit of older, solid-wall buildings where breathability is essential.
