STEICO protect L dry is a robust, render-carrying wood fibre insulation board, purpose-built for the renovation of existing masonry walls. Manufactured using a dry process, the boards are lightweight and homogenous, with straight edges for clean, easy installation.
This high-performance board is diffusion-open to allow moisture to escape, protecting the underlying masonry while improving indoor comfort year-round. Naturally resistant to algae and moss growth, it provides a durable, breathable base layer for use with EWI Pro render systems.
Sustainably made from PEFC-certified wood, STEICO protect L dry combines environmental responsibility with practical benefits—making it an ideal choice for upgrading the thermal efficiency and appearance of older masonry buildings.
