Find answers to common questions about spray foam insulation.
The R-value depends on the type of spray foam used:
Open-cell spray foam: R-3.5 to R-4 per inch
Closed-cell spray foam: R-6 to R-7 per inch
Closed-cell foam offers almost double the insulation performance per inch, making it ideal for roofs, walls, and external applications.
Yes. Open-cell spray foam is especially effective for sound reduction because of its soft, flexible, and air-absorbing structure. It helps reduce airborne noise such as voices, TVs, traffic sound, and machinery.
Closed-cell foam also reduces noise but is primarily designed for thermal performance and structural strength.
Closed-Cell Foam:
Higher R-value (R-6 to R-7 per inch)
Acts as a vapour barrier
Adds structural strength
Best for roofs, external walls, metal buildings, sheds, and commercial units
Open-Cell Foam:
Lower R-value (R-3.5 to R-4 per inch)
Excellent soundproofing
More cost-effective
Ideal for attics, interior walls, ceilings, and residential spaces
Each type is chosen based on the building requirements and conditions.
Yes. There are two primary types:
Open-Cell Spray Foam
Soft, breathable, expands greatly
Best for attics, ceilings, residential interior spaces
Closed-Cell Spray Foam
Dense, rigid, moisture-resistant
Suitable for roofs, walls, floors, sheds, containers, and commercial/agricultural buildings
Both types use NSAI-certified, Agrément-approved products.
No. Spray foam insulation should only be installed by trained, certified professionals.
The equipment, chemical handling, ventilation requirements, and correct application techniques are specialised and must meet Irish building regulations.
DIY installation can lead to health risks, poor performance, or damage to the property.
