Company Performance Metrics
Extraglaze designs, manufactures, and supplies magnetic secondary glazing systems for existing single-glazed windows. The company focuses on slim, acrylic secondary glazing panels that attach with magnets to sash, casement, stained glass, and other window types. Its systems are intended to improve thermal insulation, reduce condensation, and
provide sound reduction while retaining the appearance of original windows in period, heritage, and listed buildings. Extraglaze serves homeowners and commercial customers and offers both DIY supply-only options and a survey, supply, and fit installation service through its own team and an approved fitter network. The company also provides accessories, measuring guides, fitting guides, and aftercare materials to support installation and maintenance of its panels.
