Double Glazing

Double Glazing - Two Panels of Glass are Better than One

Double Glazing is designed to reduce the amount of warmth lost during winter and prevent unwanted heat gain during summer – helping homes stay cooler in summer and warmer in winter. They consist of two panes of glass bonded together by a spacer and separated by a argon gas filled space. The air gap acts as a thermal barrier between the inner and outer pieces of glass, creating an effective insulation system. C-View Windows double glazed products feature a warm edge spacer made of an extruded, thermoset polymer structural silicone foam which delivers exceptional thermal performance, argon gas retention and long-term durability.
