MUMBAI, India, Feb. 6 -- Intellectual Property India has published a patent application (202511132768 A) filed by Asif Hussain Shah; and Suhail Ahmad Ahanger, Srinagar, Jammu & Kashmir, on Dec. 28, 2025, for 'hollow brick wall system filled with recyclable heat-storage granules.'
Inventor(s) include Asif Hussain Shah; and Suhail Ahmad Ahanger.
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 present invention relates to a passive, energy-efficient hollow brick wall system designed to enhance thermal energy storage and heat retention in buildings. The system comprises modular hollow masonry bricks having one or more internal cavities filled with recyclable heat-storage granules selected from sensible heat materials, phase-change material pellets, composite capsules, or recycled industrial by-products. The granule-filled cavities increase the effective thermal mass of the wall, enabling absorption of thermal energy during periods of heat availability and gradual release of the stored heat over extended durations. The cavities are accessible through removable sealing means, allowing removal, replacement, or reconfiguration of the heat-storage granules for seasonal thermal performance tuning. The wall system operates without electrical, mechanical, or active control components and is compatible with conventional masonry construction practices. The invention reduces indoor temperature fluctuations, lowers heating energy demand, and supports sustainable construction through the use of recyclable and reusable materials, particularly in cold and temperate climatic regions."
