Why spray foam
Why spray-apply insulation to a Newry building?
Across Newry and the wider County Down area, a large share of working buildings are steel-framed sheds, portal-frame warehouses and older commercial units that were never insulated to today’s standards. Spray-applied foam bonds straight to the roof sheets, walls and soffits, closing air gaps and warming the inner face of the building in one continuous layer.
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 Newry 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
Local context
Spray foam for Newry’s A1/M1 corridor units and upland livestock sheds
Newry, Mourne and Down District Council describes its district as lying along the A1/M1 economic corridor that links Belfast and Dublin, and Newry, with 28,026 residents in Census 2021, is the city on that route at the head of Carlingford Lough, right on the border with Co. Louth. Where a business along the corridor works from a steel-clad unit, two roof problems usually come up together: heat escaping through bare sheeting, and condensation forming on its underside and dripping onto stock, vehicles or staff.
The countryside around Newry is livestock country. DAERA’s June 2025 census recorded 4,098 farms across the district, carrying 209,143 cattle, including 31,746 dairy cows, and 243,873 sheep, of which 122,154 were breeding ewes. Those farms stretch from south Armagh villages such as Crossmaglen and Bessbrook to the Mourne side around Kilkeel and Rostrevor. Lambing sheds and cattle houses are full of moist air for long periods, and drip from an uninsulated roof lands on young stock and their bedding.
Rainfall is on the high side. The Met Office’s Killowen station averaged about 1,061 mm a year over 1991 to 2020, on around 155 wet days, compared with about 824 mm at Armagh. Wet weather brings wet fleeces, wet bedding and wet vehicles indoors, and all of it raises the humidity inside a building. That moisture condenses wherever it meets the coldest surface, which in a single-skin shed or unit is the roof.
Closed-cell Enverge Nexseal LE is sprayed directly onto the inside of the sheeting, where it bonds and cures into a continuous insulating layer that keeps the inner face warm and closes gaps at laps, ridges and eaves. It carries a 25-year manufacturer-backed product warranty. In livestock housing the approved installer looks at ventilation alongside insulation, and in any older building confirms the roof material first, because asbestos cement sheets must be dealt with under the Control of Asbestos Regulations (Northern Ireland) 2012 before anyone sprays near them. Duratite supplies the foam and introduces a Newry customer to an approved installer.
In Newry and the rest of the district, insulation work is measured against the Building Regulations (Northern Ireland) 2012 and Technical Booklet F2, with Newry, Mourne and Down District Council as the local authority and HSENI regulating site safety. A short drive south, buildings in Co. Louth follow the Republic’s TGD L 2022 and come under the Health and Safety Authority instead. Businesses and farmers working on both sides of the border should give the installer the address of each building so the right standard is used.
Condensation, solved
Dripping roof sheets in Newry? 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 Newry building.

What building owners in Newry ask us to fix
Disruptive alternatives
Board-and-batten linings or new cladding mean scaffolding, fixings and downtime. Spray foam is applied directly to what is already there.
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.
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.
Temperature-sensitive storage
Grain stores, cold rooms and product stores need steadier internal temperatures than bare sheeting allows.

Which foam
Enverge or Purios — which suits your Newry 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 Newry building is set at survey.
Northern Ireland
Northern Ireland building regulations for insulation in Newry
In Northern Ireland, energy performance is governed by the Building Regulations (Northern Ireland) 2012, with guidance for buildings other than dwellings in Technical Booklet F2. Your survey report sets out the U-value target that applies to your Newry building and the foam build-up needed to meet it.
An EPC (Energy Performance Certificate) is required when a building in Northern Ireland is sold or let, and improving the fabric is one of the most direct ways to improve it.
Fire safety guidance in Northern Ireland is given in Technical Booklet E. Where foam is left exposed, the installer confirms whether a thermal barrier or an intumescent coating such as DC315 is required.
Site work is carried out in line with the requirements enforced by HSENI, the health and safety regulator for Northern Ireland.

Your questions answered
Frequently asked questions
Straight answers to the questions Newry building owners and managers ask most.
Do you install spray foam insulation in Newry?
Yes. Duratite Ireland takes enquiries from Newry and the wider County Down area and passes them to an approved spray foam installer who covers County Down. We do not run a branch office in Newry; the survey and installation are carried out by the approved installer, with Duratite supplying the Enverge or Purios system.
Will spray foam stop condensation in my Newry 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 Newry?
Cost depends on area, access, substrate and the thickness needed, so we do not publish a price per square metre for Newry. After the free survey you receive a written quotation in sterling from the approved installer.
What about fire safety for spray foam in Newry?
Fire safety guidance in Northern Ireland is in Technical Booklet E. 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 Newry?
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.
Will spray foam improve the EPC of my Newry property?
Better fabric performance feeds into a building’s EPC, which is required in Northern Ireland when a building is sold or let. The certificate itself is issued by an accredited energy assessor, so we cannot promise a particular rating.
Who carries out the installation in Newry?
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 Newry enquiries to approved installers.
What U-value does my Newry building need?
In Northern Ireland the target comes from the Building Regulations (Northern Ireland) 2012 and Technical Booklet F2 for buildings other than dwellings. It depends on the element and on whether the work is new build or refurbishment, so the survey report states the target for your building and the foam thickness needed to meet it.
Does spray foam suit a lambing shed in the Mournes or south Armagh?
It can cut the roof drip that soaks bedding, because Nexseal LE keeps the inner face of the sheets warmer than the air in the shed. Sheep housing still needs good ventilation, so the approved installer checks airflow and may suggest changes alongside the foam. Book early so the work is finished before lambing.
We run a unit near the A1 at Newry. Can the building stay open?
Usually in part. The area being sprayed is cleared or sheeted over and kept free of staff until the foam has cured, and the installer can often work in sections. Access, working hours and protection of stock are agreed at survey.
Which regulations apply if my unit is in Co. Louth rather than Newry?
In Newry and the rest of Northern Ireland, insulation work is measured against the Building Regulations (Northern Ireland) 2012 and Technical Booklet F2, with HSENI regulating site safety. In Co. Louth, the Republic’s TGD L 2022 and the Health and Safety Authority apply instead.
