Swisspor LambdaRoof EPS 100 - Premium Thermal Insulation for Roofs and Facades

Opt for Swisspor LambdaRoof EPS 100 Graphitised Expanded Polystyrene, a top solution for efficient thermal insulation of roofs and facades, ideal for new builds or renovations. Manufactured by Swisspor, a leader in the building materials industry, this graphitised polystyrene stands out for its improved thermal conductivity of around 20% (0.029 W/mK compared to 0.036 W/mK for standard EPS 100). Designed for external thermal insulation composite systems (ETICS), insulation of pitched roofs, floors or cold rooms, LambdaRoof EPS 100 guarantees superior energy performance and long-term durability.

Key Features

• Exceptional Thermal Conductivity: With a value of 0.029 W/mK, LambdaRoof EPS 100 significantly reduces heat loss, optimising heating and cooling costs.
• Stress Relieved Boards: Eliminates the risk of warping over time, preventing cracking, even at high thicknesses.
• Superior Elasticity: Provides excellent mechanical strength, ideal for demanding applications.
• 100% Recyclable: Environmentally friendly product, contributing to environmental sustainability.
• Compressive Strength: Minimum 100 kPa at 10% deformation according to SR EN 826/98, for durability in harsh conditions.
• Low Water Absorption: ≤3% at full immersion and ≤0.5 kg/m² at partial immersion, perfect for damp environments.
• Vapour Permeability: Microporous structure allows vapour migration, reducing the risk of condensation.

Recommended Applications

Swisspor LambdaRoof EPS 100 is designed for various applications including:

• Façade thermal insulation: used in ETICS systems according to SR EN 13499:2004, for new buildings or refurbishments.
• Pitched roof insulation: Ideal under pitched roofs for superior thermal protection.
• Floor insulation: Suitable under screeds or reinforced slabs to minimise heat loss.
• Cold rooms: Provides effective thermal insulation in temperature controlled environments.

Competitive Advantages

• Reduced Thickness Efficiency: Excellent thermal performance with thinner boards, saving space and costs.
• Crack-Free Durability: Stress-relieved boards and superior elasticity ensure extended life.
• Reduced Energy Consumption: Minimises heat transfer through infrared radiation, increasing thermal comfort.
• Quality Certifications: Conforms to SR EN 13163:2012+A1:2015, with ISO 9001:2015 and ISO 14001:2015 quality management.

Installation Recommendations

For correct application, follow the technical guidelines specific to expanded polystyrene thermal insulation:

• Check the compatibility of the substrate surface by adhesion tests (10x10 cm samples fixed with adhesive).
• Clean the surface of impurities, dust or unstable areas before application.
• For facades, fix the boards with adhesive and dowels, applying fibreglass reinforcing mesh and finishes (decorative plaster or paint).
• For roofs, make sure that the boards are protected from direct sunlight before applying the sheathing.
• In cold rooms, use low-temperature compatible adhesives and fixings.

Transport and Storage

To preserve product integrity:

• Store in dry areas away from prolonged exposure to sunlight.
• Avoid storage on edge to prevent warping of the boards.
