Wall Insulation

Wall Insulation — The High-Performance Solution for Warmer, Stronger & Moisture-Protected Buildings

Wall insulation is essential for creating a warm, energy-efficient, and durable building envelope. Using advanced spray foam technology, it delivers maximum thermal performance, superior moisture resistance, and long-lasting protection for residential, commercial, agricultural, and industrial properties. With its strong, rigid composition and exceptional sealing capability, spray foam wall insulation reinforces surfaces, prevents draughts, and stops heat escaping through external or internal walls. Ideal for concrete walls, stone structures, blockwork, steel units, farm buildings, sheds, and renovations, our wall insulation system offers unmatched thermal stability and structural reliability. Certified to European and British standards, it adheres quickly to vertical and overhead surfaces, ensuring a continuous, seamless protective layer. With professional installation and high-reactivity materials, our wall insulation solution is perfect wherever strength, airtightness, and moisture control are essential.

Key Advantages of Wall Spray Foam Insulation

Superior Thermal Performance

Provides excellent insulation value, reducing heat loss through walls and improving overall energy efficiency.

Rigid, High-Density Strength

Forms a durable, reinforcing barrier across concrete, stone, block, and metal walls — adding stability while delivering exceptional thermal resistance.

Moisture, Water & Vapour Protection

Creates a robust shield against moisture ingress, condensation, and vapour movement, preventing dampness, mould growth, and internal wall damage.

Ideal for Older or Hard-to-Insulate Walls

Perfect for solid walls, stone buildings, farm structures, and conversions where traditional insulation cannot achieve an airtight or moisture-resistant barrier.

Professional Wall Insulation Installation Done Right

We install certified spray foam systems from leading European and British manufacturers to ensure the highest levels of safety, performance, and durability. Our team is fully trained and experienced in wall insulation for homes, commercial units, agricultural buildings, workshops, and industrial facilities. Thanks to strong adhesion and high reactivity, spray foam can be applied on vertical and overhead surfaces, creating a continuous protective layer that improves structural integrity. Every installation includes a detailed assessment of ventilation requirements, substrate condition, and building compliance to deliver maximum effectiveness.

01

Concrete, Stone & Block Walls

Creates a rigid, long-lasting insulation layer that reduces heat loss and restricts vapour penetration.

02

Agricultural & Commercial Walls

Protects against condensation, corrosion, and thermal transfer, making buildings more efficient and durable.

03

Metal Panels, Units & Sheds

Reinforces metal surfaces while preventing sweating, heat loss, and internal moisture build-up.

04

Internal & External Wall Applications

Suitable for both sides of the wall structure, depending on building type and insulation goals.

05

Vertical & Overhead Surfaces

Adheres firmly to all wall types, providing a uniform insulation layer without sagging or gaps.

06

Condensation & Moisture Control

Stops dampness, mould, and vapour movement, ensuring healthier and more stable indoor conditions.

07

Long-Term Structural Protection

Strengthens walls against environmental wear, temperature changes, and ongoing moisture exposure.

08

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.
