About Roof Thermal Insulation
Roof thermal insulation is a building system designed to minimize heat transfer through the roof, enhancing energy efficiency, lowering utility bills, and creating a comfortable interior temperature. Materials like aluminum foil, foam boards, mineral wool, or specialized tiles create a barrier against solar heat gain in summer and heat loss in winter
- Mechanism: Functions by reflecting thermal radiation (aluminum foil), slowing conduction (insulation boards), or creating trapped air pockets (hollow tiles, bubble insulation).
- Common Materials:
- Reflective Insulation: Double-sided aluminum foil with polyethylene air bubbles, capable of reflecting up to 97% of radiant energy.
- Rigid Foam Boards: EPS, extruded polystyrene (XPS), or Neopor (graphite-enhanced) are stable, lightweight, and offer high thermal resistance (-value).
- Mineral Wool: Rockwool is effective for high-temperature resistance.
- Passive Systems: Hollow clay tiles provide a traditional, durable insulating barrier.
