Polycarbonate is a special type of translucent plastic that is used in most conservatory roofs. It has been developed to provide a light, inexpensive and easy to install alternative to glass, whilst still offering similar levels of heat insulation and light transmission to standard double glazing. K2 offers you the choice of 25mm or 35mm polycarbonate - with the 35mm option offering the higher level of performance due to its increased thickness.
The 35mm system, which is 40% thicker than ordinary polycarbonate provides exceptional levels of thermal insulation, keeping you warm in winter and cool in summer, whilst at the same time, reducing sound transmission and unwanted glare. Combined with high performance standards and minimal maintenance 35mm offers very real benefits to the homeowner.
