Our conservatory roof insulation system uses high performance (A) grade polished reflective film and thermal webbing giving stunning insulation benefits.

The CIS conservatory roof insualtion process effectively deals with all forms of heat transfer such as Conduction, Convection and Radiation.

Put simply the CIS conservatory roof insulation out-performs other conservatory roof insulation products on the market today. Typically, an untreated polycarbonate conservatory roof has a U-Value of 1.61w/m2k. Installing conservatory roof blinds reduces this on average to 1.42w/m2k whilst “Metal Inserts” would typically reduce the U-Value to 1.1w/m2k.

When fitting our conservatory roof insulation system a typical U-value of less than 0.18 is achieved.
