What is Spray Foam Insulation?
Spray foam insulation—also known as spray polyurethane foam (SPF) - is an alternative to traditional insulation materials. It is a liquid foam that expands upon application, creating an insulating barrier. This versatile material can be used to insulate roofs, lofts, walls, floors, and more.
Spray foam insulation has been in use for over 30 years and has gained popularity due to its high insulating properties and ability to minimise air leakage. However, it has also faced criticism due to potential drawbacks.
Types of Spray Foam Insulation
Spray foam insulation is available in two primary types: open-cell and closed-cell. Both are typically made from polyurethane and contain bubbles of gas or air, but they differ in composition and application.
Open-Cell Spray Foam Insulation
Open-cell spray foam is a lightweight, flexible insulation material applied in liquid form. It is commonly used in residential properties to insulate attics, roofs, and walls.
Closed-Cell Spray Foam Insulation
Closed-cell spray foam insulation consists of tightly packed, sealed cells that prevent air and moisture from passing through. This results in a rigid, highly water-resistant material, making it ideal for applications requiring structural reinforcement and moisture protection.
Potential Issues with Spray Foam Insulation
While spray foam insulation offers several benefits, it also presents significant challenges, including:
Difficult and Costly Removal – Once installed, spray foam insulation can be challenging and expensive to remove.
Ventilation Concerns – It may restrict airflow within the roof space, leading to increased humidity and dampness, which can accelerate timber decay.
Hazardous Fumes During Installation – The application process releases fumes that may pose health risks.
Not Suitable for Certain Properties – It is generally not recommended for listed buildings or properties with thatched roofs.
Aesthetic and Structural Impact – The application process can be messy, and the resulting appearance is often unattractive.
Impact on Property Value – Some mortgage lenders refuse to provide financing for homes with spray foam insulation, potentially reducing property value.
How Does Spray Foam Insulation Affect Property Value?
The presence of spray foam insulation can complicate property transactions. Due to concerns about condensation and structural integrity, surveyors often flag it during inspections.
According to the Royal Institution of Chartered Surveyors (RICS), properties with spray foam insulation may be subject to devaluation or require an independent specialist report. In some cases, lenders may deem a property un-mortgageable.
Efforts are underway within the spray foam industry to address these concerns. The National Insulation Association advises homeowners to obtain all relevant documentation from their installer to help mitigate valuation disputes.
