Bubblefoil® Roof Insulations

Alucushion®/Bubblefoil® FR is manufactured by a continuous lamination process of LDPE and foil with sealed bubbles of air between the two outer laminates. The thousands of individually celled air bubbles created during the manufacturing process, form a column of immobilised dry air, effectively countering heat loss through convection and conduction. Available in White or Black single-sided Foil, Double-sided Foil and White Single sided Domestic Grade.
