Closed cell spray foam insulation is an advanced insulation material widely used in Ireland for residential, commercial, and industrial buildings. It is highly valued for its dense structure, water-resistant properties, and exceptional insulating capabilities. Unlike open cell spray foam, closed cell spray foam forms a rigid, dense barrier upon application, making it particularly suitable for environments where both insulation and moisture resistance are required. Applied with a spray gun, it expands on contact to create an airtight, watertight seal that enhances energy efficiency and protects against moisture ingress.
Key Benefits of Closed Cell Spray Foam Insulation
High Insulation Value: Closed cell spray foam has one of the highest R-values per inch, meaning it provides superior insulation with less material, making it ideal for areas where space is limited.
Water Resistance: The closed cell structure makes this insulation material highly resistant to water. It acts as a barrier against moisture, preventing it from seeping through walls, floors, and roofs, which makes it especially effective for environments exposed to high humidity.
Structural Strength: Once applied, closed cell spray foam hardens into a dense, rigid layer. This added rigidity reinforces the building’s structural integrity, providing additional strength to walls, roofs, and other surfaces.
Airtight Seal: Closed cell spray foam fills all gaps and seals them tightly, creating a continuous barrier that reduces air leakage, minimizes drafts, and maintains stable indoor temperatures. This air seal contributes to improved energy efficiency and reduced heating and cooling costs.
Practical Applications of Closed Cell Spray Foam
Roof Insulation: Closed cell spray foam is particularly effective in roof insulation due to its high resistance to water and its ability to add structural strength. It’s ideal for Irish roofs, which are often exposed to heavy rain and high humidity, providing both insulation and protection against moisture.
Wall Insulation: The high R-value of closed cell spray foam makes it a popular choice for wall insulation in both residential and commercial buildings. It offers energy efficiency while acting as a moisture barrier, preventing issues like dampness and mould.
Basement and Crawl Space Insulation: Closed cell spray foam is a great option for basements and crawl spaces due to its water-resistant properties. These areas are prone to moisture issues, and closed cell spray foam helps to create a dry, insulated environment.
Exterior Applications: In addition to interior uses, closed cell spray foam is also suited for exterior insulation projects, including agricultural structures and metal buildings. It protects against external moisture while providing a strong insulating layer.
Closed cell foam is denser, water-resistant, and forms a rigid structure, while open cell foam is lighter, more flexible, and allows water vapour to pass through.
Yes, when applied by professionals, closed cell spray foam is a safe and effective choice for residential insulation, offering both energy efficiency and moisture resistance.
Closed cell spray foam is highly durable and designed to last for the life of the building without needing replacement.
Absolutely. Closed cell spray foam provides excellent insulation by creating an airtight seal, which reduces energy consumption for heating and cooling.
Yes, it’s an ideal choice for roofs as it strengthens the structure and provides a waterproof layer, protecting against moisture intrusion and enhancing insulation.
Closed cell spray foam has an R-value of approximately 6-7 per inch, making it one of the most efficient insulation materials available.
