Why Radiant Barrier Insulation Under Concrete Slabs?

The reason we insulate beneath concrete slabs is to improve thermal efficiency. In essence, you want to stop or limit heating through the slab and the ground beneath it.For more information on concrete insulation you can also browse online to https://www.maxraft.co.nz/.

While all insulations improve efficiency in thermal performance radiant barrier insulation, (also known as reflective foil) gives many other advantages too. They include:

  • Low moisture absorption
  • Radon resistance
  • termite resistance
  • Transmission of low water vapor
  • Durability
  • Easy and safe installation

The material that makes up the reflective foil insulation can be described as composed of a single or double layer of air bubbles that have been encapsulated, and some or all layers of aluminum foil reflective placed in different configurations. 

These materials aren't susceptible to absorption by water. This means that liquid moisture doesn't escape or get retained through the insulation. This is why it is ideal for concrete slabs in which concrete is generally an application with high moisture.

Nowadays, nearly all local building codes call for the installation of a radon barrier. The reflective insulation utilized in concrete slabs accomplishes this. It is extremely long-lasting with a continuous weave of aluminum foils and bubbles of polyethylene that fulfill the requirements of the radon barrier.

Reflective bubble insulation acts as an effective termite barrier and is considered to be an appropriate barrier. If you live in areas that are believed to be infested with a significant infestation, you must check with the local building codes to get appropriate guidance.

Reflective bubble insulation specifically designed to be used under concrete will effortlessly withstand the pressure of foot traffic that is required to pour concrete without breaking. In testing the compressive strength of this insulation that was designed specifically for use below the slab in a typical slab, the product was compressed by less than 10% which makes it perfect to use.

These barriers come in rolled form and are available in different sizes. The most common equipment required for installation include the sharp knife of a utility tool, an aluminum strip and an appropriate ruler. It is simple to operate and is safe to use without the need to use special equipment.
