reflective insulation

Reflective insulation is a type of material designed to reduce heat transfer by reflecting radiant heat away from or back into a space. It typically consists of a reflective surface, such as aluminum foil, combined with materials like foam or bubble wrap. When installed properly, it reflects heat radiation, helping keep a building cooler in summer and warmer in winter. Unlike traditional insulations that block heat flow through conduction or convection, reflective insulation primarily addresses radiant heat transfer, making it an effective component in energy-efficient building designs.
