Why spray foam
Why spray-apply insulation to a Lisburn building?
Farm buildings, warehouses and commercial units in Lisburn and the wider County Antrim area 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 Lisburn 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 dairy, cattle and machinery buildings around Lisburn
Dairy sits at the centre of farming around Lisburn. DAERA’s June 2025 census found 15,799 dairy cows among 68,171 cattle in the Lisburn and Castlereagh council area, spread over 881 farms and 36,118 hectares, along with 35,672 sheep. Grass takes up 28,855 hectares of that land, which means silage, cattle housed through the winter and steady demand for covered space: cubicle sheds, calf houses, parlours, dairies and machinery stores. Those farms surround a city of 51,447 people, with villages such as Moira, Glenavy, Maghaberry and Dromara on its rural side.
Each of those buildings has its own moisture problem. Cattle breathe out large volumes of water vapour, parlours and dairies are washed down daily, and silage and wet bedding add more. Under bare metal sheeting that vapour condenses as soon as the roof cools, and the drip falls onto cows, feed, milking equipment or machinery. In a calf house the damp is a welfare concern; in a machinery shed it shows up as rust on tractors and implements.
Local weather adds background humidity rather than causing the drip directly. The Met Office’s Hillsborough station averaged about 917 mm of rain over 1991 to 2020, on around 157 wet days. Air that is already damp when it comes into a shed can take up little of the moisture the animals produce, so ventilation alone struggles on still, wet days, and a cold roof surface does the rest.
Closed-cell Enverge Nexseal LE, sprayed onto the underside of the sheeting, keeps that surface warmer and seals the laps and eaves where cold air is drawn in. It carries a 25-year manufacturer-backed product warranty. It is not a substitute for ventilation, so the approved installer assesses airflow in livestock buildings before specifying a thickness. The survey also confirms what the roof is made of: older fibre cement sheets may contain asbestos, and in that case the Control of Asbestos Regulations (Northern Ireland) 2012 have to be dealt with before any spraying. Duratite supplies the foam and refers Lisburn enquiries to an approved installer.
Where insulation is being added or a farm building is being adapted for another use, the survey report should explain how the Building Regulations (Northern Ireland) 2012 and Technical Booklet F2 apply. Lisburn and Castlereagh City Council, which serves 149,100 residents or 7.8% of Northern Ireland’s population, is the building control authority, and HSENI regulates safety on site. Before the survey, list which sheds drip, when it happens, and whether stock, milk equipment or machinery sits underneath.
Condensation, solved
Dripping roof sheets in Lisburn? 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 Lisburn building.

Common issues with buildings in Lisburn
Draughts and air leakage
Open laps, ridges and eaves let wind through large buildings. Foam seals gaps as it expands, without separate tapes or membranes.
Ageing roof sheets
Older corrugated roofs can be insulated from below without stripping or overcladding, keeping the building in service.
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 Lisburn 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 Lisburn building is set at survey.
Northern Ireland
Northern Ireland building regulations for insulation in Lisburn
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 Lisburn 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
Questions from Lisburn building owners
Straight answers to the questions Lisburn building owners and managers ask most.
Do you install spray foam insulation in Lisburn?
Yes. Duratite Ireland takes enquiries from Lisburn and the wider County Antrim area and passes them to an approved spray foam installer who covers County Antrim. We do not run a branch office in Lisburn; the survey and installation are carried out by the approved installer, with Duratite supplying the Enverge or Purios system.
How much does spray foam insulation cost in Lisburn?
Cost depends on area, access, substrate and the thickness needed, so we do not publish a price per square metre for Lisburn. After the free survey you receive a written quotation in sterling from the approved installer.
Will spray foam stop condensation in my Lisburn 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.
Closed cell or open cell — which suits a building in Lisburn?
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 Lisburn?
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.
Will spray foam improve the EPC of my Lisburn 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.
What U-value does my Lisburn 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 Lisburn?
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 Lisburn enquiries to approved installers.
Will spray foam help in a calf house near Lisburn?
It can reduce drip from the roof by keeping the underside of the sheets warmer than the air inside. Calf houses also depend heavily on ventilation and on controlling draughts at animal height, so the approved installer looks at airflow too and does not treat foam as a substitute for it.
Can foam go on the roof of a dairy or parlour?
Closed-cell Nexseal LE can be applied to the underside of metal roof sheeting in many farm buildings. In a dairy or parlour, the installer plans around milking times, protects equipment and keeps the area clear while the foam is sprayed and cures. The survey confirms whether the building is suitable.
What if my shed roof near Lisburn is fibre cement rather than steel?
Older fibre cement sheets may contain asbestos. The installer establishes what the roof is made of before any work, and if it is asbestos cement the Control of Asbestos Regulations (Northern Ireland) 2012 have to be addressed first. Encapsulating the sheets may then be the more appropriate first step.
