Social & Private Housing Roof Insulation
Delivering high‑performance, compliant and cost‑effective roof insulation is essential for social and private housing projects.
Whether for new build developments or refurbishment programmes, achieving strong thermal results while maintaining practical installation methods is key.
PhotonAir multi foil insulation offers an advanced solution specifically suited to modern housing requirements, combining thermal performance, moisture control, and installation efficiency in one system.
What is PhotonAir Multi Foil Roof Insulation?
PhotonAir is an innovative 2‑in‑1 breathable multifoil insulation system that combines the thermal performance of high‑quality multi foil insulation with the proven reliability of Klober Permo® Air underlay. Designed to be installed in the same way as standard breathable roofing felt, it simplifies roofing construction while significantly enhancing overall roof performance.
At its core, PhotonAir features high‑density glass wool that traps air to minimise heat transfer. This is encapsulated between a perforated reflective lower layer and a breathable air underlay. The reflective surface helps bounce heat back into the building during colder months, while the breathable membrane allows moisture to escape, reducing the risk of condensation and associated structural issues. Once installed, PhotonAir creates a watertight barrier that upgrades the thermal efficiency of the entire roof system.
Specification for Social & Private Housing Roofs
PhotonAir is suitable for a range of rafter depths commonly used in social and private housing developments. Typical build‑ups include:
- 400mm Rafter
- Target U‑Value: 0.18 W/m²K
- PhotonAir Draped: 160mm Glass Wool
- PhotonAir Counter Battened: 120mm PIR
- 600mm Rafter
- Target U‑Value: 0.18 W/m²K
- Draped Insulation: 150mm Glass Wool
- PhotonAir Counter Battened: 100mm PIR
These configurations help meet modern energy efficiency requirements while maintaining practical roof constructions for housing developments. PhotonAir works effectively as part of this layered insulation approach, enhancing thermal performance and contributing to compliance with current building standards.
Key Benefits for Social & Private Housing Projects
One of the major advantages of PhotonAir is installation efficiency. Because it is fitted in the same manner as breathable roofing felt, it integrates seamlessly into standard roofing workflows. Crucially, it can be installed without the need for a separate vapour barrier, reducing material requirements and simplifying detailing.
PhotonAir can also be applied without counter battens, meaning there is no change to the overall roof height. This is particularly beneficial in housing refurbishment schemes where maintaining the existing roofline is important for planning, aesthetic consistency, or structural constraints.
From a performance perspective, the system enhances airtightness, improves thermal efficiency, and significantly reduces the risk of condensation. For social housing providers and private developers alike, this means improved occupant comfort, lower long‑term energy costs, and enhanced durability of the roof structure.
Ideal for New Build and Refurbishment Housing
In social housing developments, energy efficiency and long‑term performance are essential for reducing fuel poverty and supporting sustainability targets. In private housing, buyers increasingly expect high‑performance building envelopes that reduce heating costs and improve comfort levels year‑round.
PhotonAir supports both objectives by:
- Improving overall roof U-values
- Reducing thermal bridging
- Managing moisture effectively
- Simplifying construction detailing
- Supporting cost‑efficient installation
Whether used in new build estates, regeneration schemes, or private residential developments, PhotonAir provides a practical and advanced solution for modern roof insulation requirements.
A Smarter Approach to Housing Roof Insulation
Roof insulation plays a critical role in overall building performance, as a significant proportion of heat loss occurs through the roof if inadequately insulated. By combining breathable membrane technology with multi foil thermal performance, PhotonAir delivers a smarter, integrated solution for social and private housing roofs.
The result is a robust, watertight, thermally efficient roofing system that meets the demands of today’s housing sector – improving comfort for residents while helping developers and housing associations meet regulatory and sustainability targets.
For projects requiring reliable, efficient, and forward‑thinking roof insulation, PhotonAir provides a high‑performance solution tailored to the needs of modern social and private housing.
