Spray foam is a chemical product created by combining two materials, isocyanate and polyol resin, which react when mixed to expand and form an insulating barrier. This type of insulation is known for its superior ability to insulate and air-seal homes. It can be applied to various areas including lofts, walls, and ceilings, making it a versatile option for preventing heat loss.
However, as buildings age and our understanding of materials improves, the removal of outdated or improperly installed spray foam has become a necessary consideration for many. At Save Energy Insulation, we’re dedicated to helping you understand why spray foam removal can be just as important as the installation process, and how it can benefit your home’s health, efficiency, and value.
Contact usComposition and Texture: Open-cell spray foam is softer and less dense than closed-cell foam. It has a spongy texture and is made up of cells that are not completely encapsulated, which means the cells are deliberately left open. This results in the foam being more flexible and giving it sound-dampening properties.
Insulating Value: Open-cell foam typically has an R-value of about 3.5 to 3.6 per inch. While it provides significant insulation, it is less effective per inch compared to closed-cell foam, making it more suitable for interior applications where space is not a constraint.
Composition and Texture: Closed-cell foam is more rigid and dense compared to open-cell foam. The cells in this type of foam are completely closed off, which traps gas and provides a higher insulating value.
Insulating Value: The R-value of closed-cell foam is approximately 6 to 7 per inch, making it one of the most effective insulating materials per inch available. This high insulating value also contributes to the structural integrity of the application area, adding strength to walls and roofing.
Moisture Permeability: Closed-cell foam is virtually impermeable to water, making it an excellent choice for both vapor and water barriers. This characteristic makes it suitable for exterior applications and in areas prone to moisture, such as basements, crawl spaces, and under slabs.
There are two main types of spray foam insulation: open-cell and closed-cell. Open-cell foam is lighter and less dense, making it ideal for indoor sound insulation. Closed-cell foam, however, is denser and more moisture-resistant, making it suitable for both indoor and outdoor applications. Both types can dramatically improve a home’s energy efficiency but come with their own set of challenges if not installed correctly.
One of the most common reasons for removing spray foam is poor installation. This can lead to gaps in insulation, moisture problems, or uneven coverage, which not only reduces the effectiveness of the insulation but can also cause structural damage over time.
Like all materials, spray foam insulation can degrade or shift as a building settles. Degraded foam may not provide the same levels of insulation and air sealing as when it was new, potentially leading to increased energy costs.
Improperly installed spray foam can lead to poor indoor air quality. Chemicals that haven’t reacted properly during the application can emit harmful fumes. Additionally, if moisture becomes trapped by the foam, it can encourage mould growth, which is a health hazard.
Building regulations and insulation technologies evolve. What was considered top-of-the-line a decade ago may no longer comply with current standards. Removing old spray foam can allow homeowners to upgrade to newer, more effective, and more environmentally friendly insulation options.
