Why spray foam
Why spray-apply insulation to a County Down building?
If you own or manage an agricultural, industrial or commercial building in County Down, spray foam is one of the few insulation methods that can be applied to the existing structure with the building left standing and, in many cases, in use. Duratite Ireland matches your enquiry to an approved installer who covers County Down.
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 Down 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 Down? 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 Down building.
Recognise two or more of these? Spray foam is worth a survey — the free County Down survey confirms it either way.
✓
Condensation dripping from roof sheets onto stock, machinery or livestock
✓
Heat escaping through uninsulated metal roofs and walls
✓
Draughts through open laps, ridges and eaves
✓
An older corrugated roof you want to insulate without stripping or overcladding
✓
Grain stores, cold rooms or product stores that need steadier temperatures
Budget & pricing
How is spray foam insulation priced in County Down?

Common issues with buildings in County Down
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 County Down 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 Down building is set at survey.
Northern Ireland
Northern Ireland building regulations for insulation in County Down
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 County Down 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 County Down building owners and managers ask most.
Do you install spray foam insulation in County Down?
Yes. Duratite Ireland takes enquiries from County Down and passes them to an approved spray foam installer who covers County Down. We do not run a branch office in County Down; the survey and installation are carried out by the approved installer, with Duratite supplying the Enverge or Purios system.
Closed cell or open cell — which suits a building in County Down?
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.
What about fire safety for spray foam in County Down?
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.
How much does spray foam insulation cost in County Down?
Cost depends on area, access, substrate and the thickness needed, so we do not publish a price per square metre for County Down. After the free survey you receive a written quotation in sterling from the approved installer.
Will spray foam stop condensation in my County Down 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.
What U-value does my County Down 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.
Who carries out the installation in County Down?
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 Down enquiries to approved installers.
Will spray foam improve the EPC of my County Down 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.
