Mumford & Wood's timber sliding sash windows meet Approved Document Q – Security

In association with

Mumford & Wood Conservation sliding sash windows are now SBD certificated to meet Approved Document Q – Security. Recognised as Britain’s leading manufacturer of high performance, tried and tested timber windows and doors, Conservation sash windows carry additional security features that meet the requirements of Document Q Building Regulations, for the new-build housing sector.

The technicians at Mumford & Wood have innovated improvements to the existing and coordinated products in the Conservation range enabling a new higher level of security without any visible difference. These windows and doors join a certificated line up in the Conservation collection which includes SBD certificated casement windows, French doorsets, bi-folding and entrance doors.

The security standard demanded by Building Regulations, to which products are tested, is known as PAS24 but prior to this all products must be tested and rated for weather and air tightness to meet BS6375 (Parts 1 and 2). 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 its 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.
