Insulation – Complete Protection for Your Home

Types of insulation materials

Extruded polystyrene (XPS) like AUSTROTHERM STIRODUR UNIVERSALPLATE (125X60X2CM) offers superior thermal resistance and moisture impermeability, ideal for floors and foundations. Expanded polystyrene (EPS) is an economical choice for facades, while mineral wool provides excellent acoustic insulation. For sealing door frames and windows, polyurethane foams and rubber strips are practical solutions.

Thermal vs acoustic insulation

Thermal insulation reduces energy loss and heating bills — the key factor is λ (lambda) value, lower means better insulation. Acoustic insulation depends on material density and structure. Mineral wool and rock wool are premium choices for both purposes thanks to their fibrous composition.

How to choose insulation thickness

For exterior walls in moderate climates, a minimum of 10cm thermal insulation is recommended, while roofs require 15-20cm due to greater temperature differences. Floor insulation under concrete requires compressive strength of at least 200 kPa. Brands like KNAUF, AUSTROTHERM and FIBRAN provide calculators for precise thickness determination.

Installation and adhesion

Proper installation is crucial for long-term efficiency. Use specialized adhesives like CERESIT or BEKAMENT that ensure firm bonding without thermal bridges. Extruded polystyrene requires full-surface adhesion, while expanded polystyrene can be installed using the five-dot method with staggered joints.

Additional requirements and standards

For fire protection, the resistance rating is critical — EI30, EI60 or EI90 indicate protection time in minutes. Waterproofing in wet areas (bathrooms, terraces) requires vapor-permeable membranes or bituminous strips. Always verify certificates for thermal conductivity and water vapor diffusion before purchasing.
