CS 77-HI+, CS 86-HI+ & ES 50-HI+

Due to the growing demand for thermal efficiency in buildings, we have recently launched additional products within our existing window and door ranges which allow even better U values to be achieved. The new sub-systems are CS 77-HI+, CS 86-HI+ and ES 50-HI+ (formally Eco System). These products are all still available in their original format but the additional subsystems will give you even greater flexibility to meet specifiers needs. All systems are available as inward opening and outward opening in a range of colours.
CS 86-HI+ is a multi-chamber system for windows and doors that combines aesthetic design, optimal, stability and high thermal comfort. Now available with enhanced thermal performance the CS 86-HI+ can achieve a Uf (frame) Value as low as 1.0 W/m²K, making this a highly energy efficient system. CS 77-HI+ is a thermally mproved three-chamber system for windows and doors that boasts the optimum combination of safety and comfort. The system achieves a Uf Value as low as 1.5 W/m²K, making it thermally efficient window and door system.
Eco System® 50 is a cost effective well-insulated system for windows and doors, that combines aesthetic design and energy efficiency. The system’s HI+ variant achieves U values down to 1.6 W/m²K.
