Windposts

Keystone Windposts span vertically between floors to provide additional lateral support for large panels of brickwork or large panels with openings. Keystone manufactures three types of windposts.

Material Specification

Keystone Windposts are manufactured from grade 304 stainless steel (grade 316 is available if required). The Keystone Technical Team will provide full product specification and schedules.

Connections & Wall Ties

All Keystone 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

Parapet & Spandrel Windposts

All three windposts designs are available in shorter length to provide the same level of stability to parapets or below windows, commonly termed parapets or spandrel windposts respectively. These posts are designed as cantilevers and are rarely more than 1.6metres in height. The base connection is engineered to resist bending moment.
