Adding a layer of aluminium foil to your roof insulation can be a simple and effective way to boost energy efficiency. This type of insulation is particularly useful for homes with poor ventilation.
Aluminium foil reflects radiant heat rather than absorbing it, which can help to reduce heat loss in the winter and heat gain in the summer. This can lead to significant energy savings.
In fact, a study found that using aluminium foil as a roof insulation can reduce heat loss by up to 35%.

Advantages of Roof Insulation
Roof insulation is a crucial aspect of any building, and aluminum foil is a popular choice for its effectiveness. Aluminum foil is heat resistant, which means it can withstand high temperatures without compromising its insulation properties.
One of the key benefits of using aluminum foil for roof insulation is its ability to deflect intense sunlight. This prevents excessive heat from entering the house, keeping it cooler and more energy-efficient.
Aluminum foil is also waterproof and non-flammable, making it a safe choice for roof insulation. This is particularly important in areas prone to wildfires or heavy rainfall.
In addition to its thermal properties, aluminum foil is also a great sound insulator, blocking up to 85% of noise. This can be a significant advantage for homes located in noisy areas or near busy roads.
Aluminum foil's light weight and aging resistance also make it an attractive option for roof insulation. It's easy to install and can withstand the elements for a long time without showing signs of wear and tear.
Here are some key properties of aluminum foil that make it an ideal choice for roof insulation:
- Heat resistant
- Waterproof and non-flammable
- Light weight
- Aging resistant
- UV-stable
Types of Roof Insulation
Heat Reflective Insulation Sheets are designed to reflect radiant heat, reducing heat transfer and improving energy efficiency. They're typically made from a combination of materials like aluminum foil, polyethylene foam, or fiberglass.
These sheets offer excellent thermal resistance properties and are lightweight, making them easy to install. They're commonly used in roofs to keep interiors cooler in hot climates.
Here are some key features of Heat Reflective Insulation Sheets:
Aluminium
Aluminium is a popular choice for roof insulation due to its unique properties. It can withstand temperatures as low as 6-8 Degree C.
One of the key benefits of aluminium roof insulation is its high reflectivity, which can reach up to 97% in some cases. This means it can effectively reflect radiant heat back towards the source, reducing heat transfer and improving energy efficiency.
Aluminium insulation is also known for its durability and ability to withstand exposure to moisture. This makes it an ideal choice for use in high-humidity environments.
Here are some key specifications of aluminium roof insulation:
In terms of size, aluminium insulation sheets can be quite large, measuring up to 1.25 M X 60 M in some cases. This makes them easy to install and can cover a significant amount of roof space.
6mm Wrap
The 6mm wrap is a type of thermal insulation sheet material that's commonly used in roofing applications. It's available in large quantities, with a minimum order of 5000 square meters.
This material has a thickness of 6mm, making it a compact and efficient solution for insulating roofs. Its R-value is 3.20 M Degree C/W, indicating its effectiveness in reducing heat transfer.
The 6mm wrap is also highly reflective, with a reflectivity of 97%. This means it can reflect a significant amount of radiant heat, helping to keep your roof cooler in the summer and warmer in the winter.
In terms of fire safety, the 6mm wrap meets the British Standard for fire retardancy, BS 476 Part 6 Class 0 and BS 476 Part 7 Class 1. This provides an added layer of protection for your roof and building.
Here's a quick comparison of the 6mm wrap with other thermal insulation materials:
As you can see, the 6mm wrap has a slightly higher R-value than the foil backed bubble thermal wrap insulation sheet, making it a more effective insulator. However, the foil backed bubble thermal wrap insulation sheet has a slightly thicker thickness, which may be beneficial in certain applications.

12mm Reflective Roll
12mm Reflective Roll is a popular choice for roof insulation due to its high reflectivity of up to 97%. This means it can reflect a significant amount of radiant heat, reducing the amount of heat that is absorbed by your roof.
The 12mm Reflective Roll is available in a range of sizes, including 1.25 M x 30 M, which makes it easy to cover large areas of your roof. Its thickness of 12mm also provides excellent thermal resistance, helping to keep your home cool in the summer and warm in the winter.
One of the key benefits of the 12mm Reflective Roll is its lightweight design, making it easy to install and transport. With a roll weight of 16 KG, you can easily handle and maneuver the insulation to ensure a smooth installation process.
Here's a comparison of the 12mm Reflective Roll with other types of roof insulation:
As you can see, the 12mm Reflective Roll has a higher R Value than the Foil Backed Bubble Thermal Wrap Insulation Sheet, making it a more effective choice for roof insulation. Its high reflectivity and thermal resistance properties make it an ideal choice for keeping your home cool and energy-efficient.
Benefits of Roof Insulation
Roof insulation is a game-changer for any home. By installing aluminum foil insulation on your roof, you can enjoy a more comfortable living space, regardless of the season.
It's effective at insulation, which means it can keep your home cooler in the summer and warmer in the winter. This is because it acts as a barrier to the flow of heat, helping to retain a comfortable temperature inside your home.
