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

Newport grew fast around its docks and steelworks, and its housing shows it: tight Victorian and Edwardian terraces climb the hills of Stow Hill and Maindee, while interwar and post-war estates spread through Ringland, Bettws and Alway. Along the Usk and out toward Duffryn you find newer riverside developments. Each era brings a different loft — a settled terrace roof with original felt asks for a very different approach from a 1980s semi with existing wool that simply needs topping up.
We help homeowners across Newport and the surrounding Gwent area arrange loft assessments, quotations and installation. Depending on the service, work may be completed by The Insulation Company or an approved installation partner.
The older terraces around Maindee and Pill tend to have shallow lofts, awkward access over the stairs and insulation laid decades ago that has since compressed. Interwar semis in Allt-yr-yn and Christchurch usually carry thin original wool where a straightforward top-up over sound material makes sense, and many have boards dropped straight onto the joists for storage. Post-war estate housing in Bettws and Ringland varies house to house, so it pays to look at each loft individually. Newer homes near the riverfront generally have some insulation already, shifting the question toward boarding or ventilation.
The Severn estuary keeps Newport damp and mild, so ventilation deserves real attention. Cramming insulation into the eaves of an older terrace can choke what little airflow the roof has and invite condensation, so we keep the eaves clear and weigh ventilation and insulation together. Where original bituminous felt sits beneath the tiles, we check how the roof breathes before recommending any build-up.
Estuary-side humidity and higher rainfall mean condensation complaints are common in poorly ventilated Newport lofts. Insulation on its own rarely fixes a moisture problem, so we look for the real cause — blocked airflow, a roof leak or an extractor venting into the loft — before recommending work.
In Newport, cost is shaped mainly by loft access on terraced streets, whether ageing insulation needs removing, and any boarding or ventilation work. Parking and access on the older hillside roads can add to it.
Many Newport 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 Newport.
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 Newport and nearby Gwent, from Maindee, Stow Hill and Pill to Allt-yr-yn, Bettws and the riverside developments, as well as Cwmbran and Caerleon. Request an assessment and we'll confirm coverage for your postcode.
Usually, yes. A tight loft with awkward stair access changes the method and the material choice rather than ruling the job out. We assess the space, keep the eaves clear for airflow and recommend a sensible build-up.
The estuary climate keeps humidity high, so ventilation matters. If you have seen condensation or staining, we look at the cause — airflow, a leak or an extractor venting into the roof — because insulation alone will not resolve a moisture problem.
