Rigid Foam Subfloor: Enhance Comfort & Energy Efficiency

We can fullfill every insulation project you can imagine!

The foundation of any structure is essential to its stability and longevity. It is the bedrock on which buildings stand and must be sturdy and reliable. One crucial aspect of a building's foundation is the subfloor, which is the layer between the structural foundation and the finished flooring.

Traditional subfloor materials, such as plywood and particleboard, are common but may not provide the insulation and moisture resistance required for modern buildings. For this reason, builders and architects are increasingly turning to rigid foam subflooring as a durable and energy-efficient alternative.

Rigid foam subflooring is a type of insulation that provides a solid base for flooring and improves energy efficiency in buildings. It consists of a layer of closed-cell foam insulation sandwiched between two layers of oriented strand board (OSB) or plywood.

This type of subflooring has been used for decades in commercial and industrial buildings, but it is becoming more prevalent in residential construction.

The foam provides thermal insulation, soundproofing, and moisture protection, while the OSB or plywood layers contribute to the subfloor's strength and durability.

This article will explore the advantages of rigid foam subflooring, how to install it, choose the right type, and the cost and energy savings associated with using it.
