The Insulation Company helps homeowners arrange loft-insulation assessments, quotations and installation services across the UK.

A former linen town on the River Lagan south-west of Belfast, Lisburn combines an older market and industrial core with extensive modern suburban growth. Red-brick Victorian and Edwardian terraces sit around the town centre and older streets; interwar and post-war housing fills areas like Old Warren and Hillhall; and there are large suburban semis and modern estates spreading toward Hillsborough, Dunmurry and the city fringe. That range, from older terraces to newer developments, means loft work here is rarely one standard job.
We help homeowners across Lisburn and the surrounding area arrange loft assessments and quotations, and connect them with installation. Depending on the service, work may be completed by The Insulation Company or an approved installation partner.
Lisburn's older terraces often have compact, steeply pitched lofts with awkward access over a steep stair and thin insulation laid years ago and since compressed. Much of the town's stock is interwar and post-war semi-detached housing across Old Warren and Hillhall, typically carrying ageing wool that suits a top-up, frequently with storage boards laid straight onto the joists. The large modern estates that have grown around Lisburn usually have insulation already, so the question is often whether adding more, or improving ventilation and boarding, gives a worthwhile improvement rather than assuming more depth is needed.
Lisburn's wet, mild Atlantic climate makes ventilation and condensation worth close attention. Packing insulation hard into the eaves of an older terrace can block what little airflow the roof has and encourage condensation, so we keep the eaves clear and treat ventilation and insulation as one question. On older terraced roofs we assess how the covering and any ageing felt are coping before recommending a build-up.
The damp Atlantic climate makes condensation and mould common in poorly ventilated Lisburn lofts. Insulation alone will not cure a moisture problem, so we check for the real cause — airflow, a leak or an extractor venting into the loft — before recommending work.
In Lisburn, cost is driven mainly by loft access on older terraces, whether old insulation needs removing, and any boarding or ventilation work. On modern estate homes, existing insulation and access shape the job.
Many Lisburn lofts already have some insulation. Where it is sound we can top it up to a suitable wool build-up; where it is damp, contaminated or compressed we remove and replace it. A short assessment tells you which applies.
These are examples of our work elsewhere, shown to illustrate what a project involves. They did not necessarily take place in Lisburn.
Emma's front and rear bedrooms, split by a central chimney breast, both cooled quickly. We insulated the 40m² floor on both sides of the chimney to a full 300mm depth.
Example from our project library
Tom noticed condensation on the bedroom windows and rapid overnight heat loss. We gave his compact 31m² loft a full 300mm Knauf glass mineral wool layer, fitted carefully around the hatch and low edge bays.
Example from our project library
Peter's upstairs ran consistently colder than the ground floor even after a heating service. The 46m² loft was almost completely uninsulated, so we installed a full 300mm Knauf glass mineral wool layer from hatch to gable.

We help homeowners across Lisburn and nearby towns, from the town centre and older streets to Old Warren, Hillhall and the modern estates, as well as Hillsborough, Moira and Dunmurry. Request an assessment and we'll confirm coverage for your postcode.
Often, yes. Many newer homes have some insulation already, so we check whether topping it up, improving ventilation or adding boarding gives a worthwhile improvement rather than assuming more depth is needed.
The damp Atlantic climate makes ventilation important. If you have noticed condensation or staining, we look at the cause — airflow, a leak or an extractor venting into the loft — because insulation alone will not fix a moisture problem.
