4mm Alububble Double Sided
Alububble Double-Sided is engineered for high radiant heat control, using a 4mm bubble-cell core laminated with reflective foil on both the top (hot side) and bottom (cold side). This dual-foil design delivers enhanced radiant barrier performance in metal roof systems and is suitable for both domestic and industrial applications.
The product offers high thermal resistance when installed with standard air gaps, remains UV-protected, fibre-free and non-toxic, and will not crack, delaminate or discolour over time. It provides excellent vapour barrier properties and strong mechanical durability when installed under tiles, metal sheets, or over purlins.
