Bautherm W

Self-extinguishing, expanded polystyrene (EPS) boards for ETICS, engineered for high thermal insulation performance and energy efficiency.

• Use in external wall thermal insulation systems for residential, commercial, and industrial buildings
• Renovation and retrofit projects for energy efficiency improvements
• Use in combination with plasters, adhesives and reinforcement base coatings
• Available in large variety of thicknesses from 30 mm to 150 mm
• Coefficient of thermal conductivity: λ = 0,036 W / m * K

• Provides reliable efficiency for the entire life of the building
• Reduces overall energy demand of the building
• Manufactured to strict dimensional and physical specs for consistent performance.
• Lightweight, easy handling – Speeds installation and lowers façade load
• High mechanical strength – Excellent compressive, flexural, and tensile resistance
• Low water absorption – Preserves λ-value and system integrity over time
• Vapour-permeable, allows controlled drying of trapped moisture
• Excellent adhesion to cementitious layers – Strong bond with ETICS adhesives/ base coats for structural stability
• Stable moisture behaviour in ETICS – Very low uptake under render; unlike mineral wool, no capillary wicking to manage.
