The Insulation Company helps homeowners arrange loft-insulation assessments, quotations and installation services across the UK.
East of England · England
Norwich wears its long history openly: medieval lanes and listed timber-framed buildings cluster around the cathedral and Elm Hill, street after street of Victorian terrace fills the Golden Triangle off Unthank and Newmarket Roads, and post-war estates spread across Mile Cross, Heartsease and the city's outer edge. That mix means loft work here is rarely one job — a protected period roof needs a careful, breathable approach, while a 1960s semi may simply want a straightforward top-up over sound existing wool.
We help homeowners across Norwich and the surrounding Norfolk 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 terraces of the Golden Triangle and Thorpe Hamlet often have compact, steeply pitched lofts with awkward access and insulation that has settled and thinned over decades. Much of Norwich is interwar and post-war semi-detached housing across Hellesdon, Sprowston and Eaton, usually suited to a top-up over sound existing wool, frequently with storage boards laid straight onto the joists. The city's older and listed stock asks for particular care, so we look at how the roof breathes and what materials suit it rather than forcing a standard build-up.
East Anglia is comparatively dry, but Norfolk is flat, open and exposed, and Norwich lofts still see condensation where ventilation is poor. Packing insulation hard into the eaves of an older terrace blocks the little airflow the roof has, so we keep the eaves clear and treat ventilation and insulation as one question. On listed and traditionally built homes we assess breathability before recommending any change.
Cold, damp winters and poorly ventilated roof spaces make condensation a common complaint in Norwich lofts. Insulation alone will not cure a moisture problem, so we identify the real cause — airflow, a leak or an extractor venting into the loft — before recommending work.
In Norwich, cost is driven mainly by loft access on the terraced streets of the Golden Triangle, whether old insulation needs removing, the care needed on period property, and any boarding or ventilation work. Parking and access near the historic centre can also be a factor.
Many Norwich 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 Norwich.
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.
Example from our project library
We help homeowners across Norwich and nearby Norfolk, from the Golden Triangle and Thorpe Hamlet to Hellesdon, Sprowston and Eaton, as well as Wymondham, Costessey and Hethersett. Request an assessment and we'll confirm coverage for your postcode.
Often, yes, but it needs care. Older breathable roofs can be harmed by trapping moisture, so we favour suitable materials, keep the eaves clear and assess how the roof breathes rather than forcing a standard build-up.
Even in drier East Anglia, poor ventilation causes condensation. If you have noticed damp 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.
