Timber Frame Insulation

Timber Frame Insulation — The High-Performance Solution for Strong, Airtight & Moisture-Protected Timber Structures

Timber frame insulation using advanced spray foam technology is the premium choice for residential, commercial, and modular building systems that require maximum airtightness, stability, and long-term protection. Designed to bond directly to timber, sheathing, and panel surfaces, spray foam forms a continuous, rigid layer that strengthens the structure, eliminates draughts, and delivers superior thermal performance. Ideal for new-build timber homes, extensions, garden rooms, modular units, attics, and timber-framed commercial buildings, spray foam insulation ensures long-lasting efficiency and protection against Ireland’s harsh and changeable climate. With its airtight seal, moisture-resistant properties, and high insulating value, spray foam is the perfect solution for keeping timber structures warm, dry, and structurally sound throughout the year. Using fully certified European and British systems, our installation ensures reliability, adhesion, and durability on vertical, horizontal, and overhead timber surfaces.

Key Advantages of Timber Frame Spray Foam Insulation

Superior Thermal Performance

Provides exceptional insulation value per inch, significantly reducing heat loss through timber walls and panels while improving energy efficiency.

Rigid, Structural Bonding Strength

Creates a durable, high-density layer that bonds tightly to timber frames, preventing air leakage and enhancing structural stability.

Moisture, Water & Vapour Resistance

Acts as a powerful moisture barrier, preventing dampness, vapour movement, and condensation issues that can damage timber over time.

Ideal for Timber Construction & Modular Builds

Eliminates draughts, reinforces envelope integrity, and provides consistent thermal protection for modern and traditional timber-frame systems.

Professional Timber Frame Installation Done Right

We supply and install spray foam systems certified by leading European and British bodies, ensuring maximum safety and performance for all timber-frame projects. Our trained and experienced team specialises in residential timber homes, modular units, garden buildings, extensions, and commercial timber constructions. With high-reactivity materials, spray foam adheres instantly to timber surfaces — whether applied vertically, horizontally, or overhead — forming a seamless insulation envelope. Every installation includes a full assessment of ventilation, structural requirements, and compliance with building standards to guarantee optimal results and long-term building health.

01

Timber Frame Walls & Studwork

Provides a continuous insulation layer that seals gaps, reduces heat loss, and enhances structural rigidity.

02

Garden Rooms, Cabins & Modular Units

Improves comfort, prevents moisture issues, and ensures stable indoor temperatures all year round.

03

Timber Attics & Sloped Ceilings

Creates an airtight, thermally efficient barrier ideal for warm-roof and cold-roof timber structures.

04

Floors, Joists & Subfloors

Reduces air leakage and increases thermal resistance across suspended timber floors and underside cavities.

05

External Timber Panels & Sheathing

Adheres tightly to timber boards, protecting the building envelope from wind, moisture, and heat transfer.

06

Condensation & Moisture Prevention

Stops vapour penetration, mould formation, and structural deterioration in timber-based environments.

07

Long-Term Timber Protection

Reinforces the building fabric, reducing the impact of weather, humidity, and temperature fluctuations.

08

Certified Installers Nationwide

We provide professional, fully compliant installation services 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.
