Windposts

Our projects are “No Windpost” Zones!  We believe that there are a number of limitations with the design of windposts which are addressed by the Wi System. We can eliminate unwieldy, steel or concrete sections, considerably reduce costs and accelerate construction.

Overview

The Wi System is a deceptively simple, yet extremely versatile method of providing structural support to masonry panels subject to lateral loads. It will allow the uninterrupted construction of “oversize” blockwork walls with unrestrained lengths of 11m long and heights of 7m.

Hollow column and trough blocks allow the construction of integral reinforced concrete columns and beams within the blockwork construction, which eliminates the need for traditional windposts, or lintels.  This novel approach leads to significant improvements in the structural, acoustic, air permeability and fire resistance performance of the wall panels compared with the use of traditional windpost supports.  The Wi System also indisputably leads to the most aesthetic finished appearance of structural blockwork walls.

Project Benefits

In large infrastructure projects, such as rail stations and stadia, the blockwork walls will invariably be subject to significant lateral loading, which requires the adoption of structural steel sections, or concrete columns, as restraint members to support the wall panels.  Such steel columns can easily exceed 400kg, whilst concrete versions can be 1000kg each!  Imagine the difficulties involved in transporting, storing, handling and erecting support columns of these weights…

The Wi System can provide the same structural restraint with components weighing less than 25kg, which can be man-handled even in the most congested projects and working areas. By adopting the Wi System at the design stage, a whole range of significant potential Health & Safety hazards are eliminated at a stroke.
