Purlin Roll is used for insulating roof areas above purlin structures in commercial and industrial buildings. It improves thermal performance, reduces noise and enhances energy efficiency, making it ideal for warehouses, factories and large metal-roof installations.
No. Compressing Purlin Roll significantly reduces its thermal and acoustic performance. If compression is unavoidable, a bracket or rail system such as Ashgrid should be used to maintain insulation thickness and ensure the building performs as designed.
Yes. Purlin Roll is classified as Euroclass A2, meaning it is non-combustible and suitable for applications requiring superior fire safety. It has also undergone full-scale fire resistance tests under BS 476 Part 22 for added assurance.
The reinforced aluminium foil facing enhances durability and provides vapour resistance, helping prevent condensation. It also gives the roll a bright, washable finish suitable for visible roof spaces and reflective insulation benefits when installed correctly.
Purlin Roll offers excellent sound absorption. It reduces noise transfer through metal roof sheets, machinery noise and external environmental sounds, helping improve indoor comfort in warehouses, workshops and commercial facilities.
Yes. Manufactured with ECOSE® Technology, Purlin Roll contains no formaldehyde and uses bio-based binders. It has zero Ozone Depletion Potential, zero Global Warming Potential and holds a BRE Green Guide rating of A for sustainability.
While it is rot-proof and non-hygroscopic, the product should not be exposed to water for long periods. Wet insulation can temporarily affect performance. Always store the rolls indoors or under cover to prevent moisture absorption before installation.
Yes. Purlin Roll is suitable for both new and existing structures. It can be installed over existing purlins to upgrade thermal performance, reduce energy consumption and improve acoustic comfort in industrial or commercial facilities.
No. Purlin Roll is lightweight and supplied in 10 m rolls for easy handling. It can be rolled over purlins and installed quickly. However, ensuring it is not compressed is essential to maintain correct performance levels.
Purlin Roll complies with BS EN 13162 and carries certifications including ISO 9001, ISO 14001, ISO 50001 and OHSAS 18001. It has also been fire-tested under BS 476 Part 22, ensuring top-tier quality and performance standards.
