Foil insulation for Swansea's lofts, roof spaces and conversions

Swansea's hillside terraces in Mount Pleasant and Brynmill, the Edwardian and inter-war housing of Sketty, the Townhill estates and the Gower coast's bungalows all sit in one of the wettest, most exposed parts of the UK — ventilation is checked before anything else.

Swansea's housing and what it means for insulation

Hillside Victorian terraces in Mount Pleasant, Brynmill and Sketty, Edwardian and inter-war housing in Sketty and Killay, post-war estates at Townhill and Penlan, and Gower cottages and bungalows on the coast. Exposure and rain make ventilation the first survey item.

Coastal exposure around Swansea: moisture before insulation

Swansea's hillside terraces and Gower bungalows sit in one of the wettest, most exposed parts of the UK, so eaves-to-ridge ventilation and timber moisture are checked before insulation is discussed.

Salt-laden driving rain and high humidity make interstitial condensation the first risk in any roof here. The survey checks the timbers with a moisture meter, the underlay and the eaves-to-ridge ventilation before any insulation is considered; a vapour-resistant multifoil on the warm side of a well-ventilated roof reduces the risk, the same layer in an unventilated one increases it. Nothing goes in until the roof is known to be dry.

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 Swansea quotes exist.

Local projects

Documented Swansea 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 Swansea?

Yes — assessment and installation capability covers Swansea 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.

Can you survey a loft conversion in Swansea?

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.

Do you cover Brynmill?

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

My Swansea 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.
