Lonsdale rooflights certified to comply with latest Building Regulations

Specialist patent glazing manufacturer, Lonsdale Metal Company Limited, has supplied their SpanGard self-supporting, rooflights since the mid-eighties., "With the latest changes to the Building Regulations now in force", Richard Burgess, Lonsdale's sales and marketing director explained, "we decided to have this popular product independently tested and certified at the Centre for Window and Cladding Technologies Ltd based at the University of Bath, to prove that it complies with the new Regulations".

"Our bespoke SpanGard product has always been considered by the industry as a high quality and virtually air-tight structure with emphasis placed upon strength and durability. Remarkably competitive for larger spans", Burgess continued, "the very nature of the system has prevented our company competing on smaller sizes with others offering more standardised manufacture. Our ongoing investment in Computer Aided Design software and the application of the latest manufacturing techniques has enabled us to reduce prices of SpanGard so contractors can now expect to purchase a small rooflight from 1.2 x 1.2 metre for as little as £678.00 excluding VAT".

SpanGard is manufactured from the company's thermally broken aluminium bar system that incorporates extruded aluminium, cill, hip and eaves members where appropriate. Aluminium covers and flashings finish the structure externally offering high performance weathering and a thirty year design life. Life-cycle costs are claimed to be minimal as the standard mill finish or polyester powder coating supplied ensures maintenance is negligible.

Recent installations of SpanGard include; The British Museum, Buckingham Palace, 10 Downing Street and a 120 x 3.5 metre continuous rooflight at Strathclyde Police Training Centre in Scotland.
