How is it installed?
For some conservatory roof insulation installations, it is necessary to first coat the glass with a solar reflective film to prevent a build-up of heat between the existing glass roof and the insulated ceiling. Generally, this is not required for polycarbonate roofs.
Before fitting, the glass area must be carefully cleaned by the fitting team and then the film is generally applied to the inside while wet.
There are also certain situations where it is suitable to fit straight onto the glass externally. This requires a different type of film and different application methods.
