“To the untrained eye the Conservation Secure™ sash window looks no different to its predecessor, so much so that even burglars won’t see this until they have struggled with the security features and, of course, timber offers better strength to weight ratios than any other frame material,” says Frank Buckley, managing director, Mumford & Wood. “High levels of thermal, acoustic and air tightness come as standard and our products surpass the requirements of Part L Building Regulations.”
Independent research carried out on behalf of the British Woodworking Federation’s Wood Window Alliance (WWA) scheme, of which Mumford & Wood is a leading member, has proven that timber windows and doors made in accordance with their standards will last for 60 years or more and that, over time, will be carbon negative. Conservation™ products are manufactured from engineered Siberian Larch wood components that provide ultimate levels of strength and stability. With the benefits of double glazing, and optional glass specification, these products offer ultimate levels of thermal and acoustic performance with peace-of-mind security.
