This kit includes the following: 1 x SuperFOIL SFBA 0.6m x 5m (3sqm coverage)Sticky pads for installationInstallation Instructions Installation Cut the SFBA to suit the radiator size. Measure the distance between the radiator brackets, then cut a slit at the correct distance to allow the SFBA to slide down over the radiator brackets. Use the adhesive pads to keep SFBA in position. SFBA is 95% efficient at Reflecting Radiant energy. Creating an air space between your wall and SFBA will give further benefits in conduction and convection performance too.
