Foil insulation for Grimsby's housing stock
Grimsby's housing stock reflects its fishing-port history. The East Marsh and West Marsh areas close to the docks are densely-built late-Victorian fisherman's terraces, typically with slate roofs on shallow rafters and small loft voids — many still with their original lath-and-plaster ceilings. Cleethorpes, to the east, is the seaside suburb, with a mix of Victorian guesthouses along the front and substantial inter-war semis inland. Scartho, Waltham and Humberston supply the inter-war and post-war semi-detached suburban belt, and the surrounding villages of Laceby and New Waltham contribute detached housing and converted farmhouses on larger plots.
How we work in Grimsby
Grimsby's coastal and estuarine position — the Humber to the north, the North Sea to the east — puts it in one of the damper, windier microclimates we work in, and that shapes how we fit foil here. Every DN-postcode loft job gets the full coastal treatment: oversized cold-side ventilation, stainless fixings, sealed laps with approved tape, and a dedicated 25mm air gap front and back on SF19+ or SF40 installs. Fisherman's terraces in DN31 and DN32 tend to be shallow-rafter and tight-eaves, so we often use dedicated rafter spacers to maintain the gaps rather than relying on the existing timber. Out towards Waltham and Humberston the jobs get easier — more generous geometry, deeper rafters, often combined with loft-conversion projects where foil becomes part of a bigger build.
What we install
On a typical Grimsby job, we survey the roof and recommend the specific SuperFOIL product that best matches the application. SF19+ is our workhorse between-rafters product for retrofit lofts — 11 layers in a slim flexible roll that fits between shallow Victorian rafters without losing headroom. SF40 is specified where a higher U-value is needed or where the roof element is the main line of thermal defence — 37 layers, 12 reflective foils, currently the top of the SuperFOIL range. SFNC is our non-combustible variant for flats, commercial buildings and any application where fire rating drives the specification. Each product carries the full manufacturer guarantee and our own 10-year workmanship warranty.
Areas and neighbourhoods we cover
Our Grimsby crew regularly works across Cleethorpes, Scartho, Waltham, Laceby, New Waltham and Humberston, as well as the surrounding villages and towns inside the DN31, DN32, DN33, DN34, DN35, DN36, DN37 and the wider north-east Lincolnshire DN-postcode area postcode footprint. If you're outside these areas, please phone — we will almost always travel anywhere in Lincolnshire and the immediately surrounding counties for a decent-sized job.
Why a specialist matters
A general roofer can put a roll of foil between rafters in an hour. A properly-trained Superfoil contractor will take longer — because we measure and set the air gaps, tape every lap with approved foil tape, preserve the cold-side ventilation, protect the vapour control layer at every service penetration, and hand you compliance paperwork at the end. The difference doesn't show on day one, but it absolutely shows a couple of winters in — and it's the difference between a foil install that quietly performs for 50 years and one that causes condensation problems within 24 months.
Free surveys, written quotes, fixed prices
Every Grimsby job starts with a free, no-obligation site survey. We look in the loft, check the roof externally, measure the rafter depth, discuss what you're trying to achieve, and follow up within 48 hours with a written, itemised quote fixed for 60 days. There is no pressure, no call centre, and no commission-hungry salesperson. If foil isn't the right answer for your specific property, we'll tell you.
