Foil & multifoil insulation installers in Belfast

Belfast's red-brick terraces off the Ormeau and Ravenhill Roads, the inter-war semis of Finaghy and Cregagh and the estates of Rathcoole and Twinbrook sit within a province where bungalows and rural roof-space conversions are far more common than in most of Great Britain.

Northern Ireland's Technical Booklets apply, not England's Approved Documents.

Belfast's housing and what it means for insulation

Red-brick Victorian and Edwardian terraces across the Ormeau Road, Ravenhill, the Shankill and Falls, inter-war semis in Finaghy, Stranmillis and Cregagh, post-war estates in Rathcoole and Twinbrook, and suburban detached stock in Holywood, Newtownabbey and Lisburn; the surrounding countryside is bungalow and farmhouse territory.

Belfast bungalows: roof space that wants to become a room

Belfast's Ormeau and Ravenhill terraces carry the conversions; outside the city the roof being converted is usually a bungalow's, and Northern Ireland's Technical Booklets set the requirements.

Bungalow roof spaces are large, low and shallow-raftered, and converting them is the most common way to add space. Depth is the constraint: a thin certified quilt under the rafters, often with PIR between, keeps the room usable. Dormers, the long unventilated eaves runs and the position of services all need detailing, and building control treats the conversion as controlled work.

How it works, briefly

Postcode → property questions → assessment where a physical inspection is needed → recommendation → fixed quote → installation. Every step runs to the InsulationMatch installation standard; the installing company is named on the quote. Multifoil itself is explained in the multifoil guide, and what moves a price in the cost guide. Local ranges are published here only once genuine Belfast quotes exist.

Local projects

Documented Belfast projects are added to the project library as they complete. Until then the library's typical project scenarios show how the housing above is assessed.

Questions homeowners ask

Do you install foil insulation in Belfast?

Yes — assessment and installation capability covers Belfast and the areas listed on this page, allocated by postcode and project type. The check tells you the coverage position before asking for contact details.

Do you cover Bangor?

Yes, Bangor is within the Belfast service area. Enter the postcode and we confirm the position for that address.

My Belfast roof has condensation — can it still be insulated?

Not until the cause is understood. The survey checks ventilation and timber moisture first; insulating over a moisture problem seals it in.

Can you survey a loft conversion in Belfast?

Yes. A loft conversion assessment measures rafter depth and headroom, checks the ventilation path and existing insulation, and sets out the build-up with a target U-value before any quote.
