All the Products at a Glance
GUTEX fibreboards provide environment-friendly, energy-efficient and cost-effective insulation in their respective applications. Engineered to perfection, the fibreboard products create pleasant, healthy indoor environments. Their porous fibre structure facilitates vapour permeability and keeps the boards continuously “breathing”. In addition, the open pored constitution endows the boards with exceptional soundproofing properties.
