Superfoil Insulation Havant
Superfoil insulation services in Havant
At Loft Insulation Specialists, we help Havant homeowners get the most from tight roof spaces with correctly specified Superfoil multifoil insulation. With over 40 years of experience across Hampshire, we know the borough’s housing well — the post-war brick terraces of Leigh Park, the 1970s flat-roofed homes at Warren Park, and the harbour-side properties around Emsworth and Hayling Island, where build-up depth is often limited.
Superfoil combines insulation, a vapour control layer and a radiant barrier in one slim sheet, so it delivers strong U-values in around a fifth of the thickness of mineral wool — ideal where headroom is tight or a loft conversion can’t lose space. Up to 35% of your home’s heat escapes through the roof, and where a deep 300mm wool layer won’t fit, a Superfoil or hybrid build-up keeps that warmth in without stealing height.
On Havant’s low-lying, salt-laden harbour fringe, we take particular care with ventilated air gaps and vapour control so the roof stays dry. Every job comes with a free, no-obligation survey and a fixed-price quote — no high-pressure sales, no jargon, just straightforward advice.
How Havant homeowners benefit from Superfoil Insulation
These are the five key things to understand about Superfoil insulation in Havant. They explain how the product works, why it suits certain roof types, and what to expect from a professional installation.
What Superfoil insulation is and how it works
Superfoil is a certified multifoil insulation that combines insulation, a built-in vapour control layer, and a radiant barrier in one product. Reflective foil layers bounce radiant heat back into your home, while insulated waddings trap conducted heat. It achieves strong U-values in around one-fifth of the thickness of mineral wool.
Why Superfoil works in tight spaces
Superfoil’s slim, lightweight design fits confined areas like shallow rafters, narrow cavities, or loft conversions without sacrificing headroom. It achieves maximum performance in hybrid systems when paired with other insulation, making it ideal where conventional materials would be too thick.
How we install Superfoil correctly
We fix Superfoil to rafters, joists, or studs using staples, tape, or battens to create sealed, compliant air gaps. The integrated vapour control layer minimises moisture risks. Correct air gap setup is critical—without it, performance drops and condensation risk increases.
Where Superfoil works best in Havant homes
Across Havant, Superfoil earns its place where depth is short: the 1970s flat-roofed homes at Warren Park, loft conversions and room-in-roof projects, and dormer or bungalow conversions around Emsworth and Hayling Island where every centimetre of headroom counts. We also line cold party walls in the post-war terraces, building it up under rafters or between studs to suit the space.

Professional Superfoil Insulation service provided
Most Superfoil installations in Havant are completed in around 4–6 hours, usually the same day.
We protect access routes, keep dust controlled, and leave the loft tidy with all Superfoil joints properly taped and sealed.
After installation, we confirm air gap compliance, joint sealing, and provide aftercare advice to protect long-term performance.
How much does Superfoil Insulation cost in Havant?
Our Superfoil insulation typically costs between £1,200 and £1,800 for a standard Havant project, depending on roof area, rafter depth, access, and whether it is fitted on its own or in a hybrid build-up with rigid board or wool.
Superfoil earns its keep on performance: around 40mm can match roughly 150mm of mineral wool, so you reach a strong U-value without losing headroom, and for extensions we pair it with board to hit the 0.18 W/m²K target many councils set. It is made with up to 40% recycled content and lasts the lifetime of the building. We always give a fixed price after survey, with no hidden extras.
Many homes recover the cost through lower heating demand over time. If you receive certain benefits or qualify under ECO4 or the Great British Insulation Scheme, we’ll check your eligibility and can carry out the work under those schemes.

Frequently asked questions
Take a look at the Frequently Asked Questions regarding our Superfoil Insulation services in Havant.
Is Superfoil insulation better than mineral wool in Havant?
For tight spaces, yes. Superfoil reaches a comparable U-value in around one-fifth of the thickness of mineral wool — roughly 40mm can perform like 150mm of wool — so it suits Havant’s flat-roofed Warren Park homes, shallow loft conversions and room-in-roof projects where depth is limited. It combines insulation, vapour control and a radiant barrier in one slim sheet, won’t sag or settle, and is made with up to 40% recycled content.
Does Superfoil insulation meet building regulations?
Yes. Superfoil is LABC Assured, confirming Part L compliance, and each variant has a published R-value building control accepts. Getting there depends on the detailing: we leave a 25mm ventilated air gap, foil-tape every overlap, and pair Superfoil with rigid board or wool where a Havant project needs to hit the 0.18 W/m²K target. Correct air gaps and sealed joints are what make the system perform.
Will Superfoil cause condensation in Havant homes?
No, not when installed correctly. Superfoil has a built-in vapour control layer that manages moisture from the warm side. We maintain ventilated air gaps on the cold side so moisture can escape safely. Because Havant is close to the coast, we pay extra attention to air gap setup and vapour control so Superfoil performance is protected long term.
How long does Superfoil insulation last?
Superfoil lasts for the lifetime of the building with no maintenance required. The foil layers will not rot, sag, or attract pests, and the product maintains its thermal performance over 50+ years without degradation.
How quickly can you install Superfoil in Havant?
Most Superfoil installations in Havant take around 4–6 hours and are usually completed the same day. We confirm timings during survey and provide a clear schedule before installation starts.

Havant (/ˈhævənt/ HAV-ənt) is a town in the south-east corner of Hampshire, England. Nearby places include Portsmouth to the south-west, Southampton to the west, Waterlooville to north, Chichester to the east and Hayling Island to the south. The wider borough comprises the town (45,826), the resort of Hayling Island, the town of Waterlooville, and the town of Emsworth. Housing and population more than doubled in the 20 years following World War II, a period of major conversion of land from agriculture and woodland to housing across the region following the incendiary bombing of Portsmouth and the Blitz.
The old centre of the town was a small Celtic settlement before Roman times and the town’s commerce, retired and commuter population swelled after World War II so as to be usually considered economically part of the Portsmouth conurbation.[citation needed]
