Comar 5P.i ECO+ offers additional thermal performance to the Comar ECO product range: by extending the polyamide strips and inserting thermal foam, this product range will provide a future-proof solution for casement windows meeting U-values up to 2016. With more and more onus on the environment, window and door systems must be sustainable. Using aluminium the Comar 5P.i ECO+ system is 100% recyclable. Aluminium can be recycled an infinite number of times with no loss to its capability. Comar operates an Environmental Management System certified to ISO 140001. Due to its slim profiles, the Comar 5P.i ECO+ range weighs less than 0.79 kg/m and therefore achieves a Green Guide A+ rating, which can help specifiers achieve the highest BREEAM levels. For added reassurance and Comar Architectural Aluminium Systems holds both a Kitemark and Secured by Design licence for its ECO product range.
