National Building Specification (NBS)

These clauses are for the Lomax + Wood range of high performance timber windows and doors which have been produced in accordance with the industry standard.

The NBS tool is designed to make the specification process as easy as possible, with a range of product details formatted by NBS. It forms part of the services provided by RIBA, the Royal Institute of British Architects, with an aim of standardising industry information so that builders, architects, contractors and developers use a universal format. Lomax + Wood manufacture quality timber windows and doors with a range of options to create both high performance and sight lines that meet the requirements of conservation and contemporary projects. We are experts in understanding the customer’s requirements and producing the technical information required to ensure they are incorporated into the design of the made-to-order timber windows and timber doors. The sash windows, flush casements and doors that Lomax + Wood provide are designed to produce the very best in timber performance with respect to thermal performance, acoustic and security.
