With the new generation of “Unipor Silvacor” clay blocks, the Unipor Group is presenting a sustainable building material solution that also improves living comfort. Like the Coriso clay block, the Unipor W07 Silvacor contains a high thermal insulation core that consists of pure coniferous wood fibres, making it a successful combination of solid wall-building material and renewable raw material. With this clay block, Unipor has mastered the balancing act between high energy efficiency and sustainable use of natural resources. After the Unipor W07 Silvacor, other Unipor clay masonry blocks will be filled with the Silvacor-insulating material core. Besides durability and value retention, Unipor-Silvacor also boasts good recyclability: both components – clay block and insulation – can be easily separated at the end of their lifecycle.
