To ensure the effectiveness of external insulation systems, it is essential to use materials like phenolic insulation boards or other suitable insulating products. These systems must be designed and constructed according to specific guidelines to maximize thermal performance and maintain energy efficiency. The primary goal is to prevent heat loss and ensure that the insulation material performs as intended.
One critical consideration is the protection of the base layer and adhesive from freezing damage. To achieve this, the inner surface temperature of the insulation layer should remain above 0°C. Additionally, the exterior insulation system should cover all openings, such as door frames and window edges, and properly seal any thermal bridges, especially around balconies and parapets.
When comparing the thermal performance of insulated walls with non-insulated ones, the average heat transfer coefficient can increase by up to 70%, leading to significant energy loss, particularly in air-conditioned spaces. For mechanical fastening systems, such as those using EPS (expanded polystyrene) insulation boards, special attention must be given to the thermal bridging effects caused by fixing elements and support structures.
The design of the sealing and waterproofing components of the external insulation system is equally important. It must ensure that water does not penetrate into the insulation layer or the substrate. Horizontal or sloped projections, as well as areas extending below ground level, require additional waterproofing measures. Any equipment or piping installed on the external wall insulation system should be securely fastened to the base structure and properly sealed to prevent moisture ingress.
By following these principles, the durability, safety, and efficiency of the insulation system can be significantly improved, ensuring long-term performance and energy savings.
