The laminate is designed with a high-tensile polyester (PET) film as the outer protective layer, providing strength, flexibility, and resistance to environmental stress. Beneath this, a aluminum foil with a reflective surface enhances thermal insulation and radiant heat resistance. For reinforcement, a fiberglass scrim arranged in a 5×5 mm square grid is incorporated, ensuring dimensional stability and mechanical durability. The layers are bonded together using extrusion-grade polyethylene (PE), which secures adhesion and structural integrity.
