Wincro Spandrel posts, like parapet posts, are designed for use as ‘cantilevers’ and do not usually exceed 1.4 metres in height. They are designed to provide restraint to the outer cavity wall of a building, where penetrated by continuous areas of curtain walling or glazing.
The system comprises of vertical cantilever designed spandrel posts, fixed to the structural frame. Fixing to the posts, horizontal spandrel rails provides restraint at sill level and tie to the cavity wall.
Spandrel rails and connections are designed to suit specific circumstances.
Types of Spandrel Post
Our Spandrel posts are available in both angle (WPA/S) and channel (WPC/S) styles.
WPA/S Angle Spandrel posts are built into the inner leaf and ties to both leaves using one-way and two-way ties.
WPC/S Channel Spandrel posts fit within the cavity and tie to both leaves using one-way ties.
Spandrel rails (WPA/SR) and connections are designed to suit specific circumstances.
They are available in a variety of section sizes, thicknesses and sizes to suit structural loading requirements. A selection of our safe working load tables are available online and our Technical Design team will be happy to provide solutions to suit your exact situation.
In order to resist the ‘bending moment’, a large base connection is needed and this may often be impractical to incorporate within the floor or roof construction. Our Technical Design team will be pleased to calculate the ‘bending moment’ for you and advise you on the size of base plate required.

Spandrel posts can be designed to fix to all types of structure and our Technical Design team will design specific connections to the frame according to the demands of the site, type of Spandrel post, structure, fixing type and loading requirements.
All Spandrel posts and rails are supplied complete with vertically adjustable ties to suit coursing levels and necessary fixing bolts.
All Wincro Windposts are manufactured from high quality grade 1.4301 (304) stainless steel to ensure durability and long life. Our windposts can also be manufactured from grade 1.4401(316) stainless steel for corrosive environments and galvanised mild steel for internal use.
