Refurbishment of Kilcooley Primary School with Kalwall is complete. Replacing windows with purpose-made Kalwall panels gave classrooms natural diffused light, no glare or shadows, and no need for blinds. Kalwall robust, maintenance-free panel system is based on reinforced fibreglass, and is lightweight and self-supporting. It is claimed to be the most highly insulating, diffuse-light-transmitting material available, with solar-control properties superior to those of glass. Kalwall is supplied and fixed by Stoakes Systems.
