External wall insulation is a widely used solution for improving the thermal performance of building façades in both new construction and renovation projects. The insulation is installed continuously on the external side of the wall and completed with a reinforced base coat and an external finishing system.
By creating a continuous insulation layer around the building envelope, external wall insulation helps reduce heat transfer and limit thermal discontinuities at structural elements such as columns, beams and floor edges.
Ediltec offers two insulation solutions for this application: X-FOAM® WAFER, made of extruded polystyrene (XPS), and POLIISO® ED, made of rigid polyisocyanurate (PIR) foam.
X-FOAM® WAFER features a distinctive wafer-patterned surface and is available in thicknesses from 20 to 240 mm, with compressive strength from ≥ 200 to ≥ 250 kPa depending on thickness.
POLIISO® ED is faced on both sides with saturated mineralised glass fibre and provides high thermal performance, with declared thermal conductivity λD from 0.025 to 0.028 W/mK depending on thickness. It is available in thicknesses from 30 to 160 mm and provides a compressive strength of ≥ 150 kPa.
The choice of insulation product and the complete façade system should be based on the required thermal performance, substrate, building characteristics and compatibility between all components of the external insulation system.
