    What Is SuperFOIL Insulation in Suffolk, Norfolk & Essex?

    SuperFOIL is an innovative multifoil loft insulation system composed of multiple layers of aluminium foil held together with spongy foam wadding. Originally developed from reflective technology used in the NASA space programme, it represents a modern, high-performance alternative to traditional mineral wool insulation.

    Unlike conventional insulation which works by trapping air, SuperFOIL works by reflecting radiant heat — reflecting up to 95% of heat back into your home during winter and keeping solar heat out during summer. This dual-action means your home stays comfortable all year round.

    The biggest advantage? SuperFOIL achieves equivalent thermal performance at a fraction of the thickness. Traditional mineral wool needs to be 270mm thick to meet modern Building Regulations standards. SuperFOIL achieves the same performance at just 40mm — meaning you can still board your loft for storage without compromising on insulation.

    Benefits Of SuperFOIL Loft Insulation in Suffolk, Norfolk & Essex

    Effective loft insulation can dramatically reduce your energy bills, carbon footprint, and overall discomfort during cold weather. Here's why SuperFOIL is the smart choice.

    Space Saving

    At just 40mm thick, it allows you to board your loft directly over the joists for storage — impossible with 270mm of mineral wool.

    Winter Warmth

    Reflects 95% of radiant heat back into your home, instantly making upstairs rooms feel warmer and reducing heating bills.

    Summer Cool

    Unlike wool which absorbs heat, foil reflects solar gain away, keeping your loft and bedrooms cooler during hot summers.

    Moisture Resistant

    SuperFOIL's waterproof nature makes it ideal for lofts prone to dampness and condensation, with a built-in breather membrane.

    Hygienic To Install

    No itchy fibres, no sharp fragments, no allergic reactions. SuperFOIL is clean and safe to handle — unlike fibreglass or mineral wool.

    Maintains Airflow

    The built-in breather membrane filters and circulates air throughout your loft space, maintaining healthy ventilation.

    Fully Recyclable

    At the end of its lifespan, SuperFOIL is fully recyclable. It also has exceptional longevity, making it amazing value for money.

    Incredibly Versatile

    Suitable for rafters, joists, pitched roofs, flat roofs and even walls — adaptable to almost any area that needs insulating.

    Properties Best Suited To Foil Loft Insulation in Suffolk, Norfolk & Essex

    SuperFOIL is versatile enough for most property types, but it's particularly effective in these situations.

    Pitched Roof Lofts

    SuperFOIL is ideal for pitched roof setups. Fitting multifoil insulation to the rafters provides complete coverage of the loft interior, giving an extra layer of protection that's particularly useful if you use your loft for storage or are considering a loft conversion.

    The slim profile means you don't lose valuable headroom — a critical advantage over bulky mineral wool alternatives.

    Damp Or Condensation-Prone Lofts

    SuperFOIL's waterproof nature makes it the ideal choice for lofts prone to dampness or condensation. Specialised foil insulation is designed to resist moisture build-up while maintaining thermal performance.

    Combined with our damp proofing expertise, we can address the root cause and insulate in one visit.

    Period & Older Properties

    Older properties throughout Suffolk, Norfolk and Essex often have poor or non-existent loft insulation. SuperFOIL is well-suited for retrofit installation, working effectively with the existing roof structure without the need for major alterations.

    We assess every property individually to recommend the best installation approach for your specific roof type and condition.

    Signs Your Loft Insulation Needs Upgrading in Suffolk, Norfolk & Essex

    Not sure if your loft needs new insulation? Here are the telltale signs of poor or inadequate loft insulation that you should look out for.

    • Cold draughts from above

      Noticeable draughts coming from the ceiling or the loft hatch feeling cold to the touch during chilly weather.

    • Uneven temperatures between floors

      If upstairs rooms are noticeably colder than downstairs, your loft insulation is likely underperforming.

    • Rising heating bills

      If your energy bills are climbing but your usage hasn't changed, heat may be escaping through the roof.

    • Old or compressed insulation

      Mineral wool that has been squashed, become damp, or is less than 270mm deep is no longer performing effectively.

    • Condensation or mould in the loft

      Signs of moisture or mould growth suggest your current insulation isn't managing temperature and airflow properly.

    Frequently Asked Questions in Suffolk, Norfolk & Essex

    SuperFOIL is a brand of multifoil insulation composed of multiple layers of aluminium foil held together with foam wadding. Originally developed from technology used in the NASA space programme, it works by reflecting radiant heat rather than simply trapping air like traditional insulation materials. Despite its slim profile (typically 40mm), it delivers exceptional thermal performance equivalent to much thicker conventional insulation.

    SuperFOIL works by reflecting up to 95% of radiant heat back into your home during winter, and reflecting solar heat away during summer. The multiple layers of aluminium foil create a highly effective thermal barrier, while the built-in breather membrane maintains healthy airflow throughout your loft space. This dual-action means your home stays warmer in winter and cooler in summer.

    SuperFOIL offers several advantages over traditional mineral wool insulation. It achieves equivalent thermal performance at a fraction of the thickness — typically 40mm compared to 270mm for mineral wool. This means you can board your loft for storage directly over the joists without compromising insulation performance. It is also moisture-resistant, hygienic to install, fully recyclable, and does not harbour dust, allergens or vermin.

    Yes, absolutely. One of the biggest advantages of SuperFOIL over traditional mineral wool is that its slim profile allows you to board your loft directly over the insulation. With mineral wool, you would need 270mm of thickness, making it impossible to board the loft without compressing the insulation (which ruins its effectiveness). SuperFOIL solves this problem completely.

    For a standard three-bedroom property, a full SuperFOIL loft insulation installation is typically completed within a single day. Our trained installers work efficiently and leave your property clean and tidy when the job is finished.

    SuperFOIL is highly versatile and can be installed in most roof types, including pitched roofs, flat roofs and loft conversions. It is particularly effective when fitted to the rafters of a pitched roof, providing full coverage of the loft interior. We will assess your property and recommend the best installation approach for your specific roof type.

    Yes. SuperFOIL is naturally moisture-resistant and its built-in breather membrane helps control condensation by allowing moisture vapour to pass through while maintaining an effective thermal barrier. This makes it an excellent choice for lofts that are prone to dampness or condensation problems.

    Up to 25% of your home's heat can escape through an uninsulated roof. By fitting SuperFOIL loft insulation, you can significantly reduce this heat loss, leading to lower heating bills throughout the year. The exact savings depend on the size of your property and your current insulation levels, but most homeowners notice a difference immediately after installation.

    Yes. Loft insulation is one of the most cost-effective ways to improve your property's Energy Performance Certificate rating. This is particularly important for landlords, as upcoming regulations are expected to require all rented properties to achieve an EPC rating of C or above.

    Loft Insulation Questions

    How can I tell whether existing loft insulation needs checking?

    Look for areas where the material is visibly compressed, uneven, missing or affected by moisture, and note any draughts or uneven temperatures below. These signs do not identify the cause or establish what insulation is suitable; roof ventilation, wiring and the loft construction also matter. Have the conditions assessed before adding material, particularly if there are signs of a leak or damp. See related options for broader home insulation.
