Saint-Gobain Glass is launching PLANITHERM® NEO, an advanced thermal insulation glass, designed to meet the evolving performance, aesthetic and sustainability requirements of the UK window and door market.
Designed for use in both double-glazed and triple-glazed units, PLANITHERM® NEO combines outstanding thermal performance with a neutral appearance, lower reflection and high light transmission. The result is a single low-emissivity solution that supports fabricators and installers in delivering high performance windows and doors across residential new build, renovation and mixed-use applications.
Mike Butterick, Marketing Director at Saint-Gobain Glass said, “Due to launch in March 2026, PLANITHERM® NEO’s advanced surface coating delivers a more neutral colour, reduced reflection and improved optical clarity, which is particularly important in triple-glazed configurations.”
PLANITHERM® NEO has been developed as a single stock product for both double and triple-glazing and can be used in annealed or toughened form, with the coating retaining the same technical and aesthetic characteristics after toughening to BS EN 12150. This simplifies stock-holding and production planning for glass processors, while improved durability and ease of processing help ensure consistently high-quality finished units.
Sustainability is built into PLANITHERM® NEO, as up to 40 percent of the glass used in its manufacture comes from reclaimed and re-manufactured pre-consumer and post-consumer recycled glass, with no impact on product quality, performance or appearance. This is enabled through Saint-Gobain’s Glass Forever circular economy programme, which reduces raw material extraction, energy consumption and embodied carbon, supported by published Life Cycle Assessment data and an Environmental Product Declaration.
The glass is suitable for a wide range of applications including residential new builds and replacement windows and doors, larger glazed elements such as sliding and bifold doors, and non-residential or mixed-use buildings. It is available in laminated configurations for enhanced security, safety, acoustic performance and ultraviolet (UV) protection, and can be combined with other Saint-Gobain Glass products to deliver multi-functional glazing solutions.
