MUMBAI, India, Feb. 6 -- Intellectual Property India has published a patent application (202541123460 A) filed by Nandha Engineering College, Erode, Tamil Nadu, on Dec. 8, 2025, for 'pla - biochar composite roof insulation panel with integrated magnetic snap fit attachment for eco friendly thermal reduction in existing metal roofing.'
Inventor(s) include T Sathish; S Janani; KS Anshid; and R Boopathi.
The application for the patent was published on Feb. 6, under issue no. 06/2026.
According to the abstract released by the Intellectual Property India: "The newly developed material relates to a lightweight, ceo-friendly retrofit insulation panel specifically developed for metal roofing applications. The panel is manufactured from a high-performance PLAbiochar composite and incorporates a magnetic snap-fit mounting system that enables fast, non-invasive installation. The multilayer structure includes an outer UV -resistant PLA protective skin, a low-density PLA-biochar foam core with enhanced thermal insulation properties, and an inner CaCO,-reinforced PLA layer that increases stiffness and dimensional stability. High-strength neodymium magnets are encapsulated in durable PLA housings along the underside of the panel, allowing secure attachment to existing metal roofs without drilling, adhesives, or specialized tools. During installation, the panel naturally creates a ventilated air gap between the roof and the insulation layer, improving thermal resistance, reducing conductive heat transfer, and promoting passive heat dissipation. The biochar-infuscd PLA core provides low thermal conductivity, improved fire resistance, and effective acoustic dampening, contributing to enhanced indoor comfort. The system significantly lowers roof surface temperature and reduces indoor heat gain, resulting in lower cooling energy demand. The design is fully removable, lightweight, biodegradable, and compatible with sustainable manufacturing practices. Overall, the invention offers a high-performance, environmentally responsible alternative to conventional roof insulation systems."
