Closed Cell Spray Foam Insulation

Closed Cell Spray Foam Insulation

Closed Cell Spray Foam Insulation — The High-Strength Solution for Commercial & Industrial Protection

Closed cell spray foam insulation is the premium choice for commercial, agricultural, and industrial environments that require maximum durability, moisture resistance, and superior insulation performance. Designed with a high-density structure and low expansion rate, it forms a tough, rigid barrier that reinforces surfaces, improves air tightness, and protects buildings exposed to harsh weather conditions. Ideal for commercial sheds, agricultural buildings, asbestos encapsulation, shipping containers, metal units, and concrete surfaces, closed cell foam delivers long-lasting thermal efficiency and outstanding moisture defence. Certified to both European and British standards, this system offers reliable performance, fast application, and excellent adhesion to vertical, horizontal, and overhead surfaces. With professional installation and high-reactivity materials, closed cell foam is the perfect solution where strength, vapour control, and weather resistance are essential.

Key Advantages of Closed Cell Spray Foam

Superior Thermal Performance

Provides one of the highest insulation values per inch, significantly reducing heat loss and improving energy efficiency.

Rigid, High-Density Protection

Forms a dense, durable coating that reinforces metal, concrete, and asbestos surfaces — strengthening the structure while providing exceptional insulation.

Moisture, Water & Vapour Resistance

Creates a powerful barrier against water ingress, vapour movement, sweating, and condensation, especially on metal and asbestos roofs or shipping containers.

Ideal for Asbestos Encapsulation

Closed cell foam fully encapsulates asbestos roofs and walls, preventing fibre release while adding strength and long-term protection.

Professional Closed Cell Installation Done Right

We use certified systems from leading European and British manufacturers, ensuring every installation meets the highest safety and performance standards. Our team is trained and experienced in handling commercial, agricultural, and industrial spray foam applications, from sheds and workshops to containers and large-scale buildings. Closed cell insulation can be applied vertically, horizontally, and overhead thanks to its high reactivity and strong adhesion. Every project is completed with careful assessment of structural needs, ventilation, and suitability for your building type.

01

Commercial & Agricultural Sheds

Creates a durable, insulated surface that reduces condensation, heat loss, and structural deterioration.

02

Asbestos Roof & Wall Encapsulation

Safely seals asbestos surfaces, preventing fibre release and providing a rigid protective layer.

03

Shipping Containers & Metal Units

Eliminates sweating and corrosion, making containers suitable for storage, workshops, or conversions.

04

Concrete, Stone & Block Walls

Forms a tough, long-lasting insulation layer that resists vapour and improves thermal performance.

05

Overhead & Vertical Applications

High reactivity ensures excellent adhesion to ceilings, roofs, and walls in commercial environments.

06

Moisture & Condensation Control

Prevents dampness, mould, and corrosion by blocking water vapour and environmental moisture.

07

Long-Term Structural Protection

The rigid finish strengthens surfaces and shields buildings from weather, temperature shifts, and wear.

08

Certified & Experienced Installers Nationwide

We provide professional installation across Offaly, Dublin, Tipperary, Westmeath, Clare, Laois, and surrounding regions.

FAQ

Spray Foam Insulation FAQs

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 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.
