The Tredaire Granduro is an 11mm thick carpet underlay manufactured by interfloor. Manufactured from PU Foam, it offers great underfoot comfort beneath your carpets. Granduro also offers superb heat and sound insulation, offering 43db sound reduction, effectively reducing impact sound! This carpet underlay supports stretch fit installation, allowing easy carpet fitting and also making it much easier to up-lift your carpet and replace it when needs be. This is a spare roll. I brought 3 for 2 bedrooms,stairs and landing fitter managed to just use 2. I am very pleased with this underlay and the fitter found it easy to fit. I can deliver within a 10 mile radius of Burton on Trent
