John Guest Speedfit Low Fit Foil Panels are designed to be installed over existing timber or concrete floors, while maintaining a low overall floor height. The 16mm panel is lightweight with high compressive strength and is pre-grooved with return bends to eliminate the need for additional panel variations. Foil is moulded into the straight grooves to enhance system performance. Return bends can be easily cut with a small knife to suit the system design and speed up installation.
