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 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:

1. Open-Cell Spray Foam

   • Soft, breathable, expands greatly

   • Best for attics, ceilings, residential interior spaces

2. 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.
