Can polyurethane foam be used to insulate your foundation from the interior?

Effective insulation of a building’s foundation is synonymous with greater comfort and energy savings and has become a necessity for building owners. Moreover, there are now a number of high-performance insulation products that can be used to insulate foundation walls from the interior.

In this article, find out whether polyurethane foam insulation can be used for this purpose.

Polyurethane foam is a highly effective insulator

Polyurethane foam goes beyond insulation. When applied correctly, it can act as an air barrier, a vapor barrier and, of course, an insulating barrier with a very high R-value.

It therefore makes the building more energy-efficient, enabling the HVAC (heating, ventilation and air conditioning) system to deliver maximum performance with minimum energy consumption.

In short, there is no doubt that polyurethane foam, especially when it contains a large percentage of closed cells, is an insulation product that delivers enough performance to insulate foundation walls from the interior.

Properties that make polyurethane foam an ideal product for insulating foundations

Polyurethane foam is one of the most effective materials for insulating foundation walls because of its outstanding adhesion to a wide variety of substrates, including concrete.

In addition, the expansion of the foam following its application ensures that the space formed by the edge joint and the floor framing elements will be perfectly filled by the insulation. Polyurethane foam insulation is very easy to apply precisely with a specially designed gun and is also ideal for sealing the holes used to run electrical cables, plumbing pipes and air ducts. This helps minimize air exchange between the exterior and interior of the building.

Should you apply the polyurethane foam insulation yourself?

When foam insulation is applied to the entire surface of a building’s foundation walls, the workload and the amount of polyurethane foam required makes it preferable to have the operation carried out by a qualified contractor. In addition to having the skills to work quickly, these contractors are usually equipped with a truck or trailer to transport the necessary chemicals and spraying equipment.

On the other hand, for smaller insulation jobs, you can buy canisters of single-component polyurethane foam that harden on contact with ambient humidity.
