Glass Mineral Wool Rotaflex 20 cm – λ 0.033 W/mK

Glass Mineral Wool Rotaflex 20 cm – λ 0.033 W/mK

High thermal efficiency. Excellent acoustic insulation. Fire-safe and eco-friendly.

The Rotaflex glass mineral wool 20 cm (λ = 0.033 W/mK) delivers outstanding insulation performance for energy-efficient buildings. It combines excellent thermal parameters with low weight, elasticity, and easy handling — perfect for attics, roofs, ceilings, and partition walls.

Its very low thermal conductivity (λ = 0.033 W/mK) effectively reduces heat loss and enhances indoor comfort. The material is non-combustible, vapor-permeable, and dimensionally stable, guaranteeing durable and safe insulation for many years.
