5 Benefits of Foil Insulated Roofs

5 Benefits of Foil Insulated Roofs

Sep 21,2022
Roof insulation is an important part of a building as it keeps the building cool in the warmer months and warmer in the cooler months. Insulation acts as a barrier to the flow of heat, thus helping to maintain a comfortable and livable temperature within the building. On top of that, it also increases energy efficiency, as the heating and cooling systems don't have to be as hard. If you are interested in the benefits of roof foil insulation, please read on to understand the 5 benefits of aluminum foil insulated roof.

Effective insulation

The insulating properties of aluminum foil are widely recognized in the construction industry - whether it is used for roofs, walls, or windows. Aluminum is an excellent insulator because it reflects light and heat. It's like a mirror. It reflects heat to its source, keeping it away from the building. That's why it's a material used for reflective insulation.

For this reason, aluminum foil is the preferred choice for areas that require heat protection, such as roof areas. The aluminum foil keeps heat out of the building, which is important for buildings in warm climates and hot summers. The foil also keeps buildings warm during cold seasons, as it helps reflect heat away from surfaces.

Use with other insulators

Foil insulation for roofs usually has plastic bubbles in the middle. Both are effective insulators.

To better understand this, it can be helpful to understand how heat is transferred. Radiation occurs when heat is transferred from a hot surface to a cooler surface, just like how sunlight radiates. Convection is the transfer of heat through a gas or liquid. Finally, conduction refers to the transfer of heat through a material (such as a metal) that is a good conductor of heat.

The aluminum foil blocks heat radiation by reflecting heat toward the heat source. Air bubbles act as insulators by preventing heat transfer by convection and conduction. Air is a good insulator because it is difficult for heat to pass through it, so the air inside the bubbles resists temperature changes.

Good air and moisture

Aluminum foil can also help keep the temperature inside a building because it traps air. A warm area can stay warm because it keeps warm air in it.

The material is also effective at preventing evaporation. For areas exposed to moisture, aluminum foil is a good choice because it acts as a moisture barrier. The material is relatively waterproof and largely immune to moisture. This is important for roofs as it helps ensure moist air doesn't get in.

Easy to install

One of the reasons builders prefer to use aluminum foil for insulation is that it is lightweight and thin. Aluminum is flexible and easy to cut. Because the material is easy to form and handle, it is suitable for quick installation, especially when insulation is required for larger buildings

Aluminum's non-toxic and non-carcinogenic properties also make it safer to install with minimal safety equipment. It is also easy to transport as it is smaller compared to other insulating materials.

Safe and durable

Despite its lightweight properties, aluminum foil can last a long time. It is known to resist compaction, decomposition, and moisture absorption. That way, you don't need to worry about replacing insulation for years to come.

Roof foil insulation is an extremely cost-effective option for builders who focus on sustainability. After all, aluminum is a recyclable metal material that does not emit harmful fumes or substances.

Key takeaways

Aluminum foil insulation has many advantages compared to other insulators and is therefore widely used in the construction industry. Thanks to its reflective properties, it can reflect heat back to its source. It's also best used with other insulators, such as air bubbles.

Which to choose Aluminum foil coated PE or Metalized pet film coated PE ?

It depends on what product to be made in final procedure. Aluminum foil coated pe is with at least 97% reflectivity, it can be bonded to EPE foam but also most of time for laminated with bubble. Metalized pet film coated PE with lower reflectivity ,but it is with strong surface.

I am a insulated liner/bag manufacturer,what product do you suggest?

There maybe bubble lamination machines and heating pressure lamination machines in your factory, we suggest Aluminum foil 7mic+PE20mic, and Metalized PET film12mic+PE15mic.

If i would like to get a quote ,what information shall i need to know first?

You are request to telling application, material structure,thickness and roll width and quantity.

What is the MOQ and how is packaging?

MOQ is 1000kgs for each product, packaging depends on roll size, common width is 1200mm and 1500mm, length are 4000m to 5000m per roll. Rolls can be vertically packed on pallet also accept to do horizontal suspending packaging.

Is this product by wet lamination or by dry lamination?

Both wet lamination line(extrusion coating) and dry lamination line(glue coating) are equiped in our Pengyuan group.
