Why spray foam
Why spray-apply insulation to a County Longford building?
Farm buildings, warehouses and commercial units in County Longford lose heat and suffer condensation for the same reasons: bare metal sheeting, open laps and no air seal. Spray foam insulation is applied directly to the substrate, so it follows every corrugation and fixing without boards, battens or overcladding.
Both ranges are declared to EN 14315-1 and CE marked. The foam self-bonds to the substrate as it cures — no mechanical fixings. The right product and thickness for your County Longford building is set at survey.
- ✓Insulation and air seal in one application
- ✓Self-bonds to metal, concrete, masonry and timber
- ✓Applied with the building left standing, often in use
- ✓Product and thickness set at survey for your building
Condensation, solved
Dripping roof sheets in County Longford? Seal them from below.
Closed-cell spray foam warms the inner face of the roof sheet and seals open laps in one continuous layer, with no boards, battens or overcladding.
Foam or boards?
Board out, overclad — or spray?
Board-and-batten linings or new cladding mean scaffolding, fixings and downtime. Spray foam is applied directly to what is already there, sealing gaps as it expands, with no separate tapes or membranes. The free survey confirms whether it suits your County Longford building.
Recognise two or more of these? Spray foam is worth a survey — the free County Longford survey confirms it either way.

Heat escaping through uninsulated metal roofs and walls
✓
Draughts through open laps, ridges and eaves
✓

✓
Grain stores, cold rooms or product stores that need steadier temperatures

Common issues with buildings in County Longford
Temperature-sensitive storage
Grain stores, cold rooms and product stores need steadier internal temperatures than bare sheeting allows.
Condensation drip
Warm, moist air meets cold roof sheets and drips onto stock, machinery, livestock and people. Spray foam warms the inner face of the sheet and stops it at source.
Heat loss and running costs
Uninsulated metal roofs and walls let heat straight out. A continuous foam layer cuts conductive losses and air leakage together.
Disruptive alternatives
Board-and-batten linings or new cladding mean scaffolding, fixings and downtime. Spray foam is applied directly to what is already there.

Which foam
Enverge or Purios — which suits your County Longford building?
Closed cell is the usual choice for metal roofs, agricultural buildings and anywhere vapour control matters. Open cell is breathable and suits internal walls, ceilings and roof voids. The installer confirms the product after surveying the building.
| System | What it is and where it suits |
|---|---|
| Enverge Nexseal LE — closed cell | A low-emission closed-cell foam for roofs, walls and soffits where vapour control and rigidity matter, including metal-clad agricultural and industrial buildings. |
| Enverge Sucraseal — open cell | An open-cell foam for internal applications where breathability and sound absorption are wanted. |
| Purios H — closed cell | Closed-cell foam with a declared thermal conductivity of 0.0224 W/m·K, made with a new-generation foaming agent with zero ODP and low GWP. CE marked with a published Declaration of Performance. |
| Purios F — open cell | Breathable open-cell foam with a declared λD of 0.036 W/m·K for internal walls, ceilings and roof voids. CE marked with a published Declaration of Performance. |
Both ranges are declared to EN 14315-1 and CE marked. The foam self-bonds to the substrate as it cures — no mechanical fixings. The right product and thickness for your County Longford building is set at survey.
Republic of Ireland
Irish building regulations for insulation in County Longford
Technical Guidance Document L 2022 — Buildings other than Dwellings (Part L, in force 25/10/2022) sets the energy performance standard in the Republic of Ireland. For new buildings, Table 1 gives limiting average U-values of 0.16 W/m²K for pitched roofs, 0.20 for flat roofs and 0.21 for walls and ground floors.
Where work is a material alteration, Table 10 applies: 0.16 W/m²K at a pitched-roof ceiling or 0.25 at the slope, 0.25 for flat roofs and 0.35 for other walls. Your survey report shows the build-up needed to reach the relevant figure.
For new buildings TGD L 2022 gives a reasonable upper limit of 5 m³/(h·m²) at 50 Pa for air permeability, confirmed by test on completion. A continuous foam layer helps close the leakage paths that testing exposes.
A BER (Building Energy Rating) from SEAI is required when a building is sold or let. Fire performance is assessed under TGD B – Fire Safety, with materials classified to I.S. EN 13501-1.

Your questions answered
Spray Foam in County Longford: your questions answered
Straight answers to the questions County Longford building owners and managers ask most.
Do you install spray foam insulation in County Longford?
Yes. Duratite Ireland takes enquiries from County Longford and passes them to an approved spray foam installer who covers County Longford. We do not run a branch office in County Longford; the survey and installation are carried out by the approved installer, with Duratite supplying the Enverge or Purios system.
Will spray foam improve the BER of my County Longford property?
Better fabric performance feeds into a building’s BER, which is required in the Republic of Ireland when a building is sold or let. The rating itself is issued by a registered BER assessor, so we cannot promise a particular grade.
Who carries out the installation in County Longford?
An approved installer trained on the system being used. The manufacturer-backed product warranty depends on the system being installed to the manufacturer’s requirements, which is why Duratite Ireland only routes County Longford enquiries to approved installers.
What U-value does my County Longford building need?
In the Republic of Ireland it depends on whether the work is new build or a material alteration under TGD L 2022. For new buildings other than dwellings, Table 1 gives 0.16 W/m²K for pitched roofs, 0.20 for flat roofs and 0.21 for walls. For material alterations, Table 10 gives 0.25 for flat roofs and pitched roofs at the slope, and 0.35 for other walls.
Will spray foam stop condensation in my County Longford shed or warehouse?
In most metal-clad buildings, yes. Condensation forms when warm, moist air meets the cold underside of the roof sheet. Closed-cell foam bonds to the sheet and keeps its inner face warm, so the surface stays above the dew point. The survey checks ventilation and moisture sources too, because very wet uses such as livestock housing need both.
How much does spray foam insulation cost in County Longford?
Cost depends on area, access, substrate and the thickness needed, so we do not publish a price per square metre for County Longford. After the free survey you receive a written quotation in euro from the approved installer.
What about fire safety for spray foam in County Longford?
Fire safety in the Republic of Ireland is covered by TGD B – Fire Safety, with material performance classified to I.S. EN 13501-1. Where foam would be left exposed in an occupied space, the specification includes the protection required, such as a thermal barrier or an intumescent coating like DC315.
Closed cell or open cell — which suits a building in County Longford?
Closed cell (Enverge Nexseal LE or Purios H) is the usual choice for metal roofs, agricultural buildings and anywhere vapour control matters. Open cell (Enverge Sucraseal or Purios F) is breathable and suits internal walls, ceilings and roof voids. The installer confirms the product after surveying the building.
