Cavalok closes parts others can't
February 2010
Low U-values have been achieved on the Minehead Eye project, an environmentally responsible community centre now under construction, with Cavalok's BigBlok closer system for 300mm cavity walls.
Cavalok Building Products has been specified on the Minehead Eye project because it had the only system capable of being fabricated into a frame former suitable for a 300mm cavity.
Minehead Eye is a multi-million pound part lottery-funded facility aimed at 13-19 year olds. It will feature a café, shop and computer area with a viewing gallery that overlooks a two-storey skate and BMX park.
The environmentally responsive building is one of a growing number of structures in the UK to have a 300mm cavity and demonstrates the extreme requirements needed to achieve low carbon status and low U-value construction.
Cavalok is the UK’s only manufacturer of BBA-accredited cavity closer systems made from 100% post-consumer recycled PVC-U.
The 300mm cavity width specified on Minehead Eye, which includes 200mm of EPS insulation, will ensure the highest level of thermal performance is achieved through its low U-value specification. The openings were formed, and the extra wide cavity closed, using the Big Blok cavity closers that also integrate the DPC and thermal break into one simple product. This provides energy saving and reduced carbon dioxide emission by minimising air leakage and heat losses at the junction between the wall and window.
