Spray Foam Insulation
For homes, farms, and commercial buildings — open & closed-cell options
Insulation where it matters most
Spray foam reaches the areas traditional insulation can’t
Spray foam insulation is ideal for attic slopes, timber-framed roofs, warehouse decks, farm sheds and tight voids. We install both open-cell and closed-cell systems — with product and method chosen based on your building type, ventilation, and moisture risk.
Whether you're insulating a pitched roof, farm building, commercial unit or domestic attic, we’ll recommend the safest and most effective system for the job.
Open-cell vs Closed-cell: What’s the difference?
- Open-cell spray foam — breathable, flexible, ideal for attic slopes and timber roofs (ventilated applications only)
- Closed-cell spray foam — dense, rigid, vapour-resistant. Best for concrete decks, metal sheds, warehouse ceilings and underfloor voids
- We’ll confirm the correct system during your survey based on building type, roof condition and target outcome
-

Where we use spray foam
Suitable for:
- Pitched roof slopes (open-cell on breathable felt with ventilation)
- Concrete, metal, or asbestos sheeted commercial roofs (closed-cell only)
- Farm buildings — milking parlours, calf sheds, grain stores, etc.
- Under suspended floors and crawlspaces
- Curved ceilings, dormers, and retrofit airtightness upgrades
We only install spray foam where it’s safe and compliant. If another system suits your building better, we’ll tell you — and offer alternatives.
What customers say
“We used closed-cell foam on our farm shed roof — the temperature difference is incredible. Condensation is gone.”
— Tom H., Kilkenny
“Premier applied spray foam under our sloped attic roof. Huge improvement in upstairs comfort and airtightness.”
— Anna W., Clare
Spray foam done right
We follow best practice for spray foam installation — from PPE and ventilation to edge masking and depth control. We assess vapour control, airflow, and suitability before proposing foam. Where used properly, spray foam delivers unbeatable thermal and airtightness performance in tricky spaces.
All jobs are installed by trained in-house crews — never subcontracted.
Nationwide service
We insulate homes, farms and businesses across Ireland — with survey-led jobs, defined scope and proper documentation at handover.

Quick answers
Do you install spray foam on commercial roofs?
Yes — we use closed-cell foam on metal, concrete or asbestos-sheeted roofs for temperature control and condensation reduction.
What’s the difference between open-cell and closed-cell?
Open-cell is breathable and flexible — ideal for ventilated roof slopes. Closed-cell is dense and water-resistant — great for floors, decks and sheds.
Is spray foam SEAI approved?
Yes — we only use SEAI-accepted spray foam systems, with certified product and compliant install methods.
Can you spray inside a barn or shed?
Yes — farm buildings are ideal for closed-cell foam on roof decks or walls. It controls condensation and improves comfort and animal welfare.
Do I need to leave the building during install?
Usually not — but for some jobs, temporary ventilation or re-entry delay is advised. We’ll let you know before booking.
