Conservatory Roof Insulation
(5 Products)Conservatory roof insulation using premium multi-foil systems such as YBS SuperQuilt and SuperFOIL SF19+ offers an effective solution for improving year-round comfort and energy performance. Designed for quick retrofit installation beneath existing conservatory roofs, these lightweight, reflective insulation rolls minimise heat loss, reduce solar gain, and prevent condensation. When sealed with Actis Isodhesif Tape, they form a continuous vapour-controlled layer for enhanced efficiency and durability.

Understanding Conservatory Roof Insulation
Conservatory roof insulation plays a vital role in regulating temperature and improving the energy efficiency of glazed or polycarbonate roof structures.
Multi-foil insulation systems such as YBS SuperQuilt and SuperFOIL SF19+ use multiple reflective layers to control radiant heat transfer, delivering excellent thermal performance without adding excessive bulk or weight.
Traditional conservatories are prone to heat loss in winter and overheating in summer due to the high transparency of roof materials. Multi-foil insulation addresses these challenges by reflecting radiant energy, reducing heat flow, and maintaining stable internal conditions. This helps create a usable space throughout the year while lowering energy demand for heating and cooling.
These foil-based insulation rolls are ideal for internal retrofit applications where access, headroom, and load-bearing capacity are limited. Installed directly beneath roof rafters and sealed with aluminium jointing tape, they form an airtight and moisture-resistant barrier.
When combined with a suitable internal lining such as plasterboard, they provide a clean, insulated finish that meets modern performance expectations.
Material Range
- YBS SuperQuilt Multifoil Insulation 40mm (15m²/Roll): A 19-layer reflective insulation combining aluminium foils and thermal wadding for high thermal resistance in confined spaces.
- YBS SuperQuilt Multifoil Insulation 40mm (12m²/Roll): Compact roll format offering identical performance and ease of installation for smaller roof areas.
- SuperFOIL SF19+ Multi-Layer Foil Insulation 45mm (15m²/Roll): Advanced reflective insulation with enhanced emissivity control to reduce both radiant and conductive heat transfer.
- SuperFOIL SF19+ Multi-Layer Foil Insulation Roll 45mm (12m²/Roll): Smaller roll size for ease of handling and fitting in tight or irregular roof spaces.
- Actis Isodhesif Tape 100mm (25m/Roll): High-tack aluminium adhesive tape designed to seal overlaps and joints, maintaining vapour control and airtight continuity.

Related Materials and Construction Uses
Multi-foil conservatory insulation systems integrate seamlessly with timber or uPVC roof structures, vapour control membranes, and interior lining materials.
They are commonly used alongside glazing upgrades, draught-proofing systems, and roof refurbishment projects to achieve complete thermal enhancement. When sealed with Actis Isodhesif Tape, the system forms a continuous reflective barrier that enhances overall building envelope performance and long-term durability.
Frequently Asked Conservatory Roof Insulation Questions
What Is The Typical Thickness Of Conservatory Roof Insulation?
Multifoil insulation products for conservatories are typically 30-45 mm thick, offering equivalent thermal performance to around 100 mm of traditional mineral wool insulation.
What U-Values Can Be Achieved With Multifoil Insulation?
When installed correctly with air gaps, systems such as YBS SuperQuilt and SuperFOIL SF19+ can achieve roof U-values as low as 0.17 W/m²K, depending on construction type and installation method.
Is Vapour Control Important In Conservatory Roof Insulation?
Yes. Multifoil insulation provides an integrated vapour control layer, reducing condensation risk. Joints and seams should be sealed with compatible foil tape such as Actis Isodhesif Tape for airtight performance.
Can Conservatory Roof Insulation Be Installed DIY?
Installation is straightforward for competent DIY users. Rolls are cut to size and stapled to rafters, with joints taped to maintain continuity. Always follow the manufacturer’s installation guidelines and safety instructions.
Does Conservatory Roof Insulation Affect Light Transmission?
When installed beneath the roof surface, insulation reduces light entering from above but does not affect windows or glazed walls. Some users add internal ceiling finishes such as plasterboard or PVC cladding.
Are These Insulation Products Compliant With UK Building Regulations?
Multifoil insulation products like YBS SuperQuilt and SuperFOIL SF19+ are tested to BS EN 16012 and meet requirements for thermal performance and fire safety under Approved Document L.
How Long Does Conservatory Roof Insulation Last?
High-quality multifoil insulation typically lasts 40 years or more, maintaining thermal efficiency and integrity when correctly installed and protected from moisture ingress.
