T&I Sealed Units LTD is Tamworth's ONLY Kitemarked and CE approved Double and Triple Glazing Insulated Glass Manufacturers. We originally were founded in 1978 as Thorpe and Ingley Glass and Window Company and Dave Jones is now celebrating his 25th Year of Ownership. Over the years the company has transferred from the production of making units for its own use and fitting windows to specialize in the manufacturing of the highest quality kitemarked sealed units. We were awarded The British Standard Kitemark for BS5713 in 2002 and our license number is KM60296 allowing for us to produce and distribute all of our manufactured products, including Lead, Stains and Georgians.
