CA Group, the Durham-based building envelope manufacturer, has built a huge distribution warehouse at Houghton Main in Barnsley, using 46,800m² of Twintherm roof, and 6,900m² of Twintherm cladding. To finish the project, 975m of insulated Therma gutter and 650m of the uninsulated were also used. Low air permeability was accomplished without specialist skills or enhanced detailing, according to Stuart McConnell, the group's roofing technical director: 'The low rating was achieved by attention to detail. CA create as standard 'robust details' for the perimeter of a building which conform to building regulations and make the building incredibly air tight.' Recent environmental concerns have placed air tightness high on the list of concerns for designers and architects. A low permeability rate means more warm air is retained in the building, therefore heating costs and environmental impact are reduced. The air tightness performance of the warehouse is proven by a U value which meets the required building regulation standards. The warehouse, which celebrated its opening with a circus, contains 77 levelling

A new approach to rainwater management is the claim being made by the County Durham-based CA Group for its recently launched Caskade Hydra system. The system is designed to allow rainwater to be rapidly routed away from large building roofs while eliminating internal pipework. The high capacity hydraulic system features sealed rainwater chambers built into the body of the specially calibrated gutters, meaning discharge pipework is not required inside a building. It has been tested by the University of Sheffield, whose engineers have built a full-scale operating test facility and by UKAS, the United Kingdom Accreditation Service.

Granted to CA Building Products is a patent for its new Therma Gutter TE. The product has notches cut out from the gutter flange to reduce heat conduction from the building interior through to the gutter. It reduces the amount of linear heat that is lost through the gutter detail. Insulated with rock fibre slab, it achieves building regulations compliance and non-combustibility.

Creation of London Metropolitan University?s graduate centre has included the use of bespoke rainscreen design from Execa ? the architectural engineering arm of the CA Group. The design was inspired by the Orion constellation, with the stellar effect achieved largely by the cladding system. Some 2000 triangles in a wide variety of sizes were used for the project.
