Foundation insulation
Foundation insulation can be carried out both internally and externally using closed-cell polyurethane foam.
When choosing materials for foundation insulation, it is essential to consider moisture absorption and compressive strength. Proper protection against moisture is critical, as excess water can reduce insulation performance and damage the foundation structure over time.
Low water-absorption insulation materials provide long-lasting performance and maintain their effectiveness even in demanding conditions. It is also important to select materials with low thermal conductivity, allowing for a thinner insulation layer while achieving high energy efficiency.
This helps reduce the overall thickness of the foundation and prevents unnecessary increase in wall dimensions, ensuring both structural efficiency and optimal insulation performance.
External Foundation Insulation
For external foundation insulation, high-density closed-cell polyurethane foam is one of the most suitable materials. It provides an airtight and durable insulation layer that adheres well to uneven and rough surfaces.
Closed-cell polyurethane foam offers excellent resistance to ground pressure and moisture, making it ideal for below-ground applications. It forms a seamless, joint-free layer, eliminating gaps and ensuring long-lasting insulation performance.
Internal Foundation Insulation
Insulating the foundation or basement from the inside is important, as a significant amount of heat can be lost through the underground part of the building. Using closed-cell polyurethane foam helps reduce heat loss and lower heating costs.
Insulating basement walls with polyurethane foam also protects against cold surfaces, helps control moisture, and reduces the risk of mould, improving overall indoor comfort and durability.
Polyurethane foam is especially suitable for insulating uneven, rough, or stone foundations, as it adapts perfectly to the surface and ensures full coverage.
