Open Cell Spray Foam Insulation is gaining popularity in Ireland as a versatile, efficient insulation material for residential and commercial properties. Known for its unique ability to expand and seal even the smallest gaps, this insulation type is highly effective for a range of applications, including attics, walls, floors, and roofs. It is applied on-site using a specialized spray gun, where the foam expands to over 200 times its original size, creating an airtight barrier that minimizes heat loss and stabilizes indoor temperatures.
Key Benefits of Open Cell Spray Foam Insulation
Efficient Application: Open cell spray foam can be applied quickly, even in hard-to-reach areas. Its expansion capability allows it to penetrate nooks and crannies that would otherwise remain exposed with traditional insulation methods.
Breathability: One of the unique properties of open cell spray foam is its "breathability," which permits water vapour to escape from the structure. This feature helps regulate moisture, preventing the buildup of harmful mould and dampness within the walls and roof.
Long-Lasting Airtight Seal: Unlike other insulation types, open cell spray foam maintains its airtight properties throughout the life of the building. This long-term performance reduces the need for future insulation upgrades, making it a cost-effective choice.
Adaptable for Roofs and Attics: Open cell foam is especially popular for attic conversions. Once applied between rafters, an insulated board can be added directly to the rafters, transforming attics or lofts into comfortable, temperature-controlled living spaces. Because the foam expands to fill every gap, it creates an optimal thermal barrier, reducing heat loss and boosting Building Energy Ratings (BER).
Practical Applications of Open Cell Spray Foam
Attic Insulation: Attics are among the most common areas for open cell spray foam insulation. Due to its expansive properties, it easily fills every gap, providing a consistent, airtight seal that minimizes heat loss and improves energy efficiency.
Wall Insulation: Internal wall insulation with open cell spray foam significantly reduces heat loss and enhances soundproofing. It’s ideal for new builds and timber frame constructions, providing both quick application and long-lasting insulation.
Floor Insulation: Often overlooked, floors account for up to 15% of a home’s heat loss. Open cell spray foam can be applied beneath floorboards, efficiently filling gaps to provide a continuous thermal barrier.
Roof Insulation: Insulating roofs under tiles and slates is challenging with traditional materials. However, open cell spray foam can access these hard-to-reach spaces, creating an airtight seal that enhances thermal performance.
Open cell foam is lighter and has a more flexible structure, allowing air to pass through while still providing insulation. Closed cell foam is denser and more rigid, making it a better moisture barrier but less breathable.
Yes, open cell spray foam is safe when properly applied. It provides excellent insulation while also allowing moisture control, reducing the risks associated with trapped dampness.
This insulation type is long-lasting and typically does not need replacing. It maintains its insulating properties and airtight seal for the life of the building.
Absolutely. By creating an airtight seal, open cell spray foam reduces heat loss, helping to maintain a stable indoor temperature and reducing energy consumption.
Yes, open cell spray foam can be applied directly to roofing felt, provided the roof has been counter-battened, ensuring proper ventilation and insulation performance.
Yes, open cell spray foam’s breathability makes it ideal for damp climates, as it allows moisture to escape, minimizing the risk of mould and mildew.
