IG Windpost Systems

IG Windposts span vertically between floors to provide additional lateral support for large panels of brickwork or large panels with openings. It is often difficult to provide suitable justification that masonry walls have lateral stiffness and therefore construction would traditionally be strengthened by the addition of thicker walls or by including columns, to effectively shorten the span of the masonry panel.

IG manufacture three types of windpost. The U Windpost is installed within the cavity and will normally span between floor structures, with the same principle applying to the DU Windpost. Both designs leave the inner leaf of the cavity wall undisturbed. The LP Windpost is designed to be built into the inner skin of the cavity wall and normally span between floor structures.

Windpost Design

IG Windposts are manufactured from grade 304 stainless steel (grade 316 is available if required). The IG Technical Team will provide full product specification and schedules.
All three Windpost designs are available in shorter lengths to provide the same level of stability to parapets or below windows, commonly termed Parapet or Spandrel Posts respectively. These posts are designed as cantilevers.

All IG Windposts are supplied with specifically designed base and upper connections and fixings. They are also supplied with a suitable number of wall-ties which will
vary in relation to the post type used and the cavity width. There are five types:

• U Tie – For use with U & DU Windposts.
• L50 Tie – For use with LP Windposts (50mm cavity).
• L75 Tie – For use with LP Windposts (75mm cavity).
• L100 Tie – For use with LP Windposts (100mm cavity).
• L Shear Tie – For use with LP Windposts.
• L Shear Tie can be supplied with a de-bonding sleeve if the windpost is positioned at a vertical movement joint.

Windpost Loadings

The loadings quoted for the windposts are derived from an allowable stress value of 181N/mm2 and a deflection limit of span/360 (the lesser of the two resultant figures is used as the quoted figure). Please note the quoted loadings are working/characteristic loads.

Windposts can be made to order at various sizes on a project basis. Post taken as a simply supported beam.
SWL’s quoted are assuming adequate base and top fixing to concrete. For other substrates please contact the IG Technical Team.
