SuperFOIL offers a range of insulation rolls designed for different applications. These include:

  • Standard Insulation Rolls: Ideal for basic insulation needs, providing an effective thermal barrier.
  • SFTV Rolls: These are versatile, suitable for use in roofs, walls, and floors. Their varied thicknesses cater to different insulation requirements.
  • SFBA MP Rolls: Specialised for use in both new construction and retrofit projects, these rolls offer enhanced thermal performance.
  • SFUF, SF19 Plus, SF40, and SF60FR Rolls: These products are designed for more demanding insulation requirements, offering higher insulation values and specific features like fire resistance.

Specialised Insulation Kits

  • Shed Insulation Kits: These are pre-packaged solutions for insulating small structures like sheds, offering convenience and ease of installation.
  • General Purpose Wraps and Pipe Wraps: Designed for specific applications like wrapping pipes or insulating small areas.

Thinsulex Multi Foil Insulation

Thinsulex offers high-performance multifoil insulation solutions, including:

  • TLX Gold and Silver Rolls: These products provide superior thermal performance and are suitable for a wide range of applications.
  • TLX Multifoil in Various Colours: Tailored for aesthetic preferences without compromising on insulation quality.

ACTIS and YBS Products

  • ACTIS HControl Series: These products are known for their hybrid insulation properties, offering both thermal and moisture control.
  • YBS Breatherquilt and Superquilt Rolls: These multilayer insulation products are designed for breathability and high thermal performance, suitable for roofs and walls.

Multifoil Roof Insulation

Multifoil roof insulation is a modern, high-performance insulation solution made from multiple layers of reflective foil combined with insulating wadding, designed to improve thermal efficiency while taking up minimal space. It works by reflecting radiant heat back into the building while also reducing heat loss through conduction and convection, helping to maintain comfortable indoor temperatures all year round.

Selection Guide

When choosing the right multifoil insulation, consider:

  1. Application Area: Roofs, walls, floors, or specific structures like sheds.
  2. Thermal Requirements: Higher R-values for more demanding environments.
  3. Space Constraints: Thinner products for limited spaces.
  4. Special Features: Like fire resistance or breathability, depending on the project needs.

Complete Your Multifoil Insulation Project with the Right Materials

If you're working on loft or roof insulation projects, our Loft Insulation range provides additional thermal protection, helping you meet building regulations and improve overall energy efficiency. For projects requiring higher thermal resistance in limited spaces, consider Celotex Insulation Boards, which deliver excellent performance across walls, floors, and roofs.

By integrating these products with multifoil insulation, you can create a complete insulation system that improves comfort, reduces heat loss, and ensures long-term performance.

Frequently Asked Questions – Multifoil Insulation

What is multifoil insulation?

Multifoil insulation is a high-performance insulation material made from multiple layers of reflective foil and insulating wadding. It works by reflecting heat and reducing heat transfer through conduction, convection, and radiation.

How does multifoil insulation work?

Multifoil insulation works by reflecting radiant heat back into the building while trapping air between its layers to reduce heat loss. It also helps control moisture through built-in vapour barriers, improving overall energy efficiency.

What are the benefits of multifoil insulation?

Multifoil insulation offers several key benefits:

  • Excellent thermal performance
  • Space-saving thin design
  • Moisture and condensation control
  • Easy installation
  • Reduced energy bills

Its reflective layers can significantly reduce heat loss and help maintain a consistent indoor temperature.

Where can multifoil insulation be used?

Multifoil insulation is highly versatile and can be used in:

  • Roofs and lofts
  • Walls (internal and external)
  • Floors
  • Conservatories and outbuildings

Its flexible design makes it ideal for tight or awkward spaces.

Is multifoil insulation easy to install?

Multifoil insulation is lightweight, flexible, and easy to cut, making it suitable for both professional installers and DIY projects. It typically requires minimal tools and creates little mess during installation.

How long does multifoil insulation last?

Multifoil insulation is highly durable and can last for decades without degrading, maintaining its thermal performance over time.
