Foil Loft Insulation Installed in Edinburgh
These images are from an installation of YBS superquilt multi foil insulation installed in the loft of a recording studio in Edinburgh.
The goal was to keep the roof and studio cooler, especially the recording booth’s which can get very warm in summer months.
YBS superquilt foil insulation will achieve this, as well as retaining more heat and keeping the building warmer the rest of the year.
Like many of the lofts we work in, this one already had mineral wool on the floor, which combined with superfoil insulation, ensures you get the maximum insulation performance from your roof and loft area.
The guys did a great job of insulting the attic of our recording studio. They adapted around some tricky issues that arose and made sure we were consulted every step of the way. Highly recommend

Foil Loft Insulation Edinburgh
This was for a home in Edinburgh, to ensure a functional loft space was warm enough for use.
Foil insulation also provides extra space vs other materials, which meant the loft area square meterage was utilised to its maximum.
Foil insulation also makes areas cooler in the summer and with this area being used by a family, this allows for an additional functional area of the home all year round.
Once again, YBS super quilt multi foil was used for this installation.
Guys did a great job. Has helped warm up the loft and given a spacey theme for a lounging about area. Fast, clean, efficient, friendly.

What is SuperFoil Insulation?
SuperFOIL insulation is a high performance, multi layer reflective insulation product designed to improve the thermal efficiency of buildings. It consists of multiple layers of reflective foil, insulating wadding, and breathable membranes that work together to reduce heat loss, reflect radiant heat, and help control condensation.
Unlike traditional insulation materials that primarily slow heat transfer through thickness, SuperFOIL combines reflective technology with insulating layers to help reduce heat loss through radiation, conduction, and convection.
We tend to almost always install YBS SuperQuilt insulation, which almost all of the information on this blog relates to.
How does Super Foil Insulation Work?
SuperFOIL products combine three forms of insulation:
Reflective insulation – reflects radiant heat back into the building.
Thermal insulation – reduces conductive heat transfer through the structure.
Vapour control – helps manage moisture and reduce the risk of condensation.
SuperFOIL insulation works by combining multiple layers of reflective foil, insulating wadding, and air gap technology to reduce heat transfer in three ways: radiation, conduction, and convection.
Reflects Radiant Heat – The outer foil layers reflect radiant heat back towards its source. During winter, heat generated inside the building is reflected back indoors, while in summer, external heat is reflected away from the building.
Reduces Conductive Heat Loss – The internal layers of insulating wadding create a barrier that slows the transfer of heat through the material itself, helping to keep warm air inside during colder months.
Minimises Convection – When installed with the recommended air gaps, SuperFOIL helps reduce air movement around the insulation. This limits heat loss caused by convection currents.
Controls Moisture and Condensation – Many SuperFOIL products incorporate vapour-resistant or breathable layers that help manage moisture movement through the building structure, reducing the risk of condensation and damp related issues.
By tackling all three forms of heat transfer radiation, conduction, and convection, SuperFOIL provides a comprehensive insulation solution for roofs, walls, floors, and other building applications.
Why Air Gaps Are Important
Reflective foil insulation performs best when installed with adjacent air spaces. These air gaps allow the foil surfaces to reflect radiant heat effectively. Without them, the reflective benefits are significantly reduced.
Benefits of SuperFoil Loft Insulation
YBS SuperQuilt is a multi-layer reflective insulation designed to improve thermal performance while saving space. It combines 19 layers of aluminium foil, insulating wadding, and foam to provide insulation, vapour control, and airtightness in a single product.
Listed below are some of the main benefits of installing superquilt foil insulation.
Space Saving Design
At around 40mm thick before installation, SuperQuilt can provide high thermal performance without the thickness of traditional insulation materials, making it ideal for loft conversions and areas where space is limited.
Excellent Thermal Performance
The multi-layer construction helps reduce heat loss by addressing radiant, conductive, and convective heat transfer. It's reflective outer layers enhance overall thermal efficiency.
Built-In Vapour Control Layer
When properly taped and sealed, SuperQuilt acts as a vapour control layer, helping to reduce moisture movement and the risk of condensation within the building structure.
Easy To Install
Lightweight, flexible, and easy to cut, SuperQuilt can often be installed more quickly than rigid insulation boards and requires no specialist equipment.
Suitable for All of Home
Can be used in roofs, lofts, walls, floors, extensions, timber-frame buildings, and refurbishment projects. It is suitable for both new-build and retrofit installations.
Moisture Resistant
Unlike some traditional insulation materials, SuperQuilt does not absorb moisture, helping it maintain its thermal performance over time.
Other Super Foil Insulation Materials
As well as SuperQuilt foil insulation, SuperFOIL offers a wide range of multi-foil insulation products designed for different loft and roof applications. The most suitable type depends on the available space, desired thermal performance, and whether the project is a new build or retrofit.
SuperFoil 19+
A popular choice for lofts and roofs, offering a balance of thermal performance and thickness. Suitable for many retrofit and new build projects where space is limited.
SuperFoil 40
A higher performance multi-foil insulation with additional layers for improved thermal efficiency. Often used in roofs, loft conversions, and timber frame constructions.
SuperFoil 60
One of the highest-performing SuperFOIL products, featuring multiple reflective and insulating layers. Ideal for projects requiring maximum thermal performance with minimal thickness.
SuperFoil Underfloor
Although designed primarily for floors, it can be used alongside loft insulation systems where a complete building insulation solution is required.
SFTV (Vapour Control Layer)
A reflective vapour control membrane used in conjunction with insulation systems to help reduce condensation and improve airtightness.
YBS SuperQuilt
For homeowners looking to maximise insulation performance while preserving internal space, YBS SuperQuilt is a popular alternative or supplement to traditional mineral wool and rigid board insulation systems.

Super foil insulation products such as SuperQuilt only achieve their stated performance only when installed according to the manufacturer’s specification, including the required air gaps and sealed joints. Building professionals and building science discussions often emphasise that installation quality is critical to achieving the expected thermal performance.
For homeowners looking to maximise insulation while preserving internal space, YBS SuperQuilt is commonly used either as a standalone solution in approved constructions or alongside traditional insulation materials to meet specific thermal performance targets.
How To Install SuperQuilt Foil Insulation
YBS SuperQuilt is typically installed beneath roof rafters, on walls, or across loft structures. Correct installation is essential to achieve the advertised thermal performance and vapour-control benefits.
Step 1: Prepare the Area
Ensure rafters, joists, or wall studs are clean, dry, and structurally sound.
Measure the area and cut the SuperQuilt to size using sharp scissors or a utility knife.
Step 2: Fix the First Run
Roll out the SuperQuilt either horizontally or vertically, depending on the rafter layout.
Pull the insulation taut and staple it securely to the rafters or timber framework at regular intervals.
Step 3: Overlap and Seal Joints
Overlap adjoining sheets by at least 50mm.
Tape all joints and seams using foil insulation tape to create a continuous airtight layer.
Step 4: Seal Around Eaves and Edges
Carefully cut around rafters, wall plates, and other obstructions.
Tape and seal all perimeter details to maintain airtightness and vapour control.
Step 5: Create the Required Air Gap
Install timber counter battens over the SuperQuilt to create an air space.
Typical battens are approximately 25mm × 38mm, although requirements may vary by application. Air gaps are important because reflective foil insulation performs best when adjacent to still air spaces.
Step 6: Install the Internal Finish
Fix plasterboard or another internal lining to the battens.
When properly taped and sealed, SuperQuilt can act as a vapour control layer, reducing the need for a separate membrane in many installations.
Installation Tips
*Follow the manufacturer’s instructions for your specific roof, wall, floor, or loft application.
*Ensure all joints are taped and sealed.
*Maintain recommended ventilation where required.
*Do not compress the insulation excessively.
Check local building regulations and thermal performance requirements before installation.
