The ICF 500 Render System gathers thermal effectiveness of a Nudura ICF system and durability of Dryvit finishing materials. Providing permanent insulated formwork and a render finish for external walls in domestic and non-domestic buildings, the system solution comprises of a reinforced basecoat, primers, finishes and decorative coatings.
With full BBA approval, the ICF 500 system contributes to sustainability targets by maintaining the continuity of thermal insulation at junctions, as well as enabling both airtightness and weathertightness. This protects the ICF structure from water ingress whilst maintaining a desirable, decorative finish. The building can be designed to include all the aesthetic benefits of an EWI system including grooves and decorative shapes. The ICF 500 system can be designed to achieve either a 30 or 60 year service life, depending on the requirements and materials used.
How does it work?
The basecoat is prepared and trowel-applied to the external face of the prepared Nudura form work. The reinforcement mesh is immediately positioned into the basecoat and trowelled into position. Additional basecoat is applied to fully embed the mesh. After the basecoat has fully cured, the primer is applied, followed by the Dryvit EWI finish and where relevant the decorative basecoat layer.
