IG Masonry Support Windposts

IG windposts span vertically between floors to provide additional lateral support for large panels of brickwork or large panels with openings. They are designed for a quick and easy installation without affecting the brickwork.

IG Masonry Support manufacture a wide range of windposts in a range of sizes to suit a variety of applications.


Connections & Wall Ties

All IG Windposts are supplied with a complete package of connections and wall ties including 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
L75 Tie For use with LP Windposts
L100 Tie For use with LP Windposts
L Shear Tie For use with LP Windposts

All of our windposts are laser cut, meaning that when all factors are controlled, laser cutting is more stable, reliable and extremely accurate compared to other cutting processes. Where the tolerance on the plasma cutter is around 2mm – the laser cuts much more accurately and can be as little as 0.1mm.


U Windposts

  • The U windpost is designed for standard loading conditions.
  • It is installed within the cavity and normally spans between floor structures.
  • The inner leaf of the cavity wall is totally undisturbed.
  • Available in shorter lengths for parapets or below windows.

DU Windposts

  • The DU is a heavier duty variant of the U windpost.
  • It is a “back to back” channel section designed for heavier loading conditions.
  • It is installed within the cavity leaving the inner leaf of the cavity wall is undisturbed.

LP Windposts

  • The LP windpost is an “L” shaped section designed to suit a range of loading conditions.
  • It is built into the inner skin of the cavity wall.
  • The LP normally spans between floor structures.

Parapet and 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 window posts respectively. These posts are designed as cantilivers and are rarely more than 1.6 metres in height. The base connection is engineered to resist bending movement.
