Roof insulation panels are installed in houses to reduce summer heat gain and reduce cooling costs. Aluminum foil insulation is a highly reflective material that reflects radiant heat instead of absorbing it. Aluminum foil can reflect up to 96% of radiant heat. Aluminum is a very cost-effective, easy to form and adaptable material, which is very suitable for wall and roof insulation.
Aluminum foil is an ideal partner for composite insulation materials and is very durable due to the protective coating. This makes aluminum foil one of the most widely used materials in the field of house insulation. The most commonly used alloy numbers for thermal insulation roof aluminum foil are 1100, 8011, etc.
What are the benefits of aluminum foil insulation for roofs?
1. Good heat reflection performance: Aluminum foil can reflect more than 95% of solar radiation, effectively reducing the heat absorbed by the roof.
2. Lightweight and easy to install: Aluminum foil is lightweight, easy to install, and can be combined with other materials such as foam board, wood board, etc.
3. Durability: Aluminum foil has good corrosion resistance and is not susceptible to moisture, mold or rust.
4. Environmental protection and energy saving: Reduce indoor cooling needs, reduce air conditioning energy consumption, and save electricity bills.
5. Suitable air and moisture: Aluminum foil helps maintain the temperature inside the building and can capture air.
Application methods of aluminum foil for thermal insulation roofs:
1. Combining aluminum foil with thermal insulation materials: A common practice is to attach aluminum foil to thermal insulation materials (such as polyurethane foam or polystyrene board) to further improve the thermal insulation effect.
2. Direct use of aluminum foil on the roof surface: A layer of aluminum foil can also be laid on the roof surface to reduce the heat load of the building by reflecting sunlight.
This insulation method is suitable for roof systems of residential, commercial and even industrial buildings, which can improve the comfort of the building and reduce energy consumption by effectively blocking the transfer of heat.
