This radiant barrier insulation is constructed with double-sided aluminum foil and an internal air bubble layer, designed to reflect up to 97% of radiant heat and reduce heat transfer, helping keep indoor spaces cooler in summer and warmer in winter for improved energy efficiency and comfort. The lightweight and flexible material can be easily cut and installed on a variety of surfaces, making it suitable for attics, garage doors, windows, walls, and floors. For added convenience, this product includes 2 rolls of foil tape (each 20 m x 5 cm) for easy installation, secure attachment, and effective sealing of seams to enhance overall insulation performance, and it is not intended for direct exposure to open flames or high heat sources.
