Windpost

A windpost is a structural item used in the design and construction of exterior masonry walls to protect them against damage from the abnormal horizontal forces imposed by high wind speeds.[1] They are normally constructed from steel channel sections and are designed to be installed within a cavity wall, supported at the head and the foot between floor slab levels and/or the principal steelwork sections forming the structural frame of the building. The windpost will typically be fixed into the inner and outer leafs of the wall by specialist fixings and fastenings at regular intervals along its length. The windposts will be spaced along the exterior walls of the building at regular intervals as calculated by the engineer to suit the required wind loadings.
