After spray foam removal
A high-performance replacement once spray foam is gone.
If your loft has had spray foam insulation removed — often following a mortgage or survey concern — SuperFOIL SF19+ can be an excellent replacement insulation system. Its thin multifoil build-up can be fitted within the roof space as part of a properly designed installation, helping restore usable loft insulation without the bulk of traditional material.
LoftServ assesses the roof construction, ventilation and available space before recommending the right approach for your property.

A clear introduction
What is SuperFOIL SF19+?
SuperFOIL SF19+ is a multifoil insulation product designed for use in roofs, walls and other building applications, depending on the installation specification.
In simple terms, multifoil uses several lightweight reflective and insulating layers in one product. Unlike conventional mineral wool, which is normally installed as a deeper layer between or over structural timbers, multifoil forms part of a specified system with the correct air spaces, joints and detailing.
The right build-up depends on your property. LoftServ will assess the roof construction, existing insulation and ventilation before making a recommendation.
Technical informationFinal product specifications and installation details should always be checked against the manufacturer’s current documentation.
Why loft insulation matters
Up to25%
of a home’s heat can be lost through an uninsulated roof
Don’t heat the loft. Keep the heat where it belongs.
SuperFOIL SF19+ is designed to help reduce heat transfer while using a relatively thin insulation build-up, making it particularly useful where roof space is limited. Its reflective foil layers are designed to bounce radiant heat back into the living space below, rather than letting it escape through the roof.

Space-conscious insulation
Why consider SuperFOIL SF19+?
For the right roof or loft, a multifoil system can offer a practical route where available depth and the finished construction matter. Every loft is different.
Multilayer construction
Reflective and insulating layers work together within a correctly designed system.
Range of applications
Designed for suitable roof, wall and other building applications.
A property-led system
Specified around the property, required air spaces and installation guidance, with lightweight handling on site.
No one product is automatically best for every loft. Performance depends on the complete build-up, detailing and installation.
A balanced comparison
SuperFOIL or traditional loft insulation?
The appropriate solution depends on available space, existing insulation, roof construction, ventilation, condensation considerations, the desired finished build-up and your property’s requirements.
| Consideration | SuperFOIL SF19+ | Traditional mineral wool |
|---|---|---|
| Physical thickness | A thinner product profile within a specified system | Usually installed at a greater depth |
| Space requirements | May be considered where space is constrained | Needs sufficient depth for the specified layer |
| Installation approach | Fixed, joined and detailed with required air spaces | Typically laid between and/or over joists |
| Typical applications | Suitable roof, wall and refurbishment build-ups | Commonly used at loft floor level and in other suitable areas |
| Handling | Lightweight rolls with careful taping and detailing | Bulkier material cut and fitted to the area |
| Suitability | Depends on the complete system and roof design | Depends on access, space, ventilation and intended loft use |
| May be considered when | Depth, construction or the desired finish favours multifoil | A conventional deeper insulation layer is appropriate |
The right insulation depends on the loft.
When space and construction matter
When could SuperFOIL SF19+ be a good option?
- Limited available insulation depth
- Roof spaces where reducing thickness is important
- Loft or roof areas where a multifoil system is appropriate
- Homeowners exploring alternatives to conventional insulation
- Certain refurbishment projects
Suitability depends on the existing construction, available space and proposed insulation build-up. We assess the loft before recommending the appropriate approach.

Helpful answers
SuperFOIL SF19+ questions
What is SuperFOIL SF19+?
SuperFOIL SF19+ is a multilayer foil insulation product designed for suitable roof, wall and other building applications. The exact specification depends on the construction and the manufacturer’s installation guidance.
How does multifoil insulation work?
Multifoil products combine reflective layers with insulating layers. They are installed as part of a designed build-up, including the required air spaces, rather than simply laid like conventional mineral wool.
Can SuperFOIL SF19+ be used in a loft?
It can be considered for suitable loft and roof applications. We first inspect the roof construction, available space, existing insulation and ventilation before discussing an appropriate approach.
Is SuperFOIL suitable for every loft?
No single insulation is right for every property. Suitability depends on the loft, roof construction, condensation risk, ventilation and the intended finished build-up.
How thick is SuperFOIL SF19+?
Product dimensions and the space needed for the complete installed system should be checked against current manufacturer documentation. We do not quote one thickness without considering the proposed build-up.
Can SuperFOIL be installed alongside other insulation?
It may form part of a combined insulation system where the design and manufacturer guidance allow. Existing materials and the whole construction need to be assessed first.
Can SuperFOIL replace traditional loft insulation?
In some suitable designs it may be considered as an alternative or part of a wider system. It is not a universal like-for-like replacement, so the right answer depends on your property.
How much does SuperFOIL SF19+ cost?
Cost varies with the area, access, roof shape, preparation and installation specification. LoftServ provides a clear quotation after assessing the property.
Does SuperFOIL reduce energy bills?
Insulation can help reduce unwanted heat transfer when correctly specified and installed, but savings vary by property, heating use and the complete construction. We do not promise a guaranteed bill reduction.
How long does installation take?
Timescales depend on the size, access, preparation and required build-up. We explain the likely programme with your quotation after the assessment.
Do I need to remove my existing insulation?
Not always. We inspect its type, condition and position before recommending whether it can remain, needs improving or should be removed.
Will my loft need ventilation?
Ventilation and condensation control are important parts of roof insulation design. Requirements vary, so these are considered during the assessment and installation planning.
Is SuperFOIL SF19+ a good replacement after spray foam removal?
It can be. Once spray foam has been removed — often following a mortgage or survey issue — SuperFOIL SF19+ can be fitted as a designed multifoil insulation system within the roof space. We assess the construction, ventilation and available space before recommending the appropriate replacement approach for your property.
Can LoftServ assess my loft before I decide?
Yes. LoftServ offers a free, no-obligation assessment to inspect the space, understand your aims and talk through suitable insulation options.
