Albotherm raises £151k to scale smart glass technology

Passive cooling technology developer Albotherm Ltd has secured an estimated £151.4k in its latest funding round. This investment brings the total capital raised by the Bristol-based firm during 2026 to £391.2k. The transaction values the business at an estimated £4m post-money.

Incorporated in 2020, the company manufactures temperature-responsive coatings designed to lower carbon emissions. Its technology regulates heat in buildings, greenhouses, and indoor-farming environments by switching from transparent to opaque to reflect solar energy without requiring external power. These solutions target commercial applications within the construction, horticulture, and agricultural sectors.

The business reported a headcount of 13 staff members in its latest accounts for the year ended 31 January 2026. This funding round follows the filing of formal documentation in June (allotment date June 2026).
