Designed by Wembley Innovation Limited, WI Product System is located in Wembley, United Kingdom. The means of achieving good conditions are understood, but the construction of extensive internal blockwork walls with large openings for air conditioning ducting and other services is complex. The use of WI beams and columns by Pyramid Builders to subdivide the large spans and to withstand the internal design pressures is a world first. Bond beams have been understood for some time and used e.g. as lintels.
Similarly reinforced hollow blockwork is known to resist wind or earth loads. The WI system has taken this to another level. Innovative designs of the critical cleats and connectors transform standard techniques into a system that enables large walls with large openings to be designed and built retaining clean architecturally desired outcomes. There is no longer the need to interrupt large spans with intermediate columns, piers or reinforced concrete beams.
