Wincro WPA Windposts

Our WPA Windposts are ideal for use in buildings subjected to high wind loads and for reduced cavity applications.

The main windpost leg is built into the inner leaf of the blockwork and tied using one-piece, two way ties.

These allow vertical movement of the structure without internal cracking.

In situations where you need to incorporate a vertical movement joint, we recommend the use of plainend, two way ties with debonding sleeves.

WPA Windposts are available in a variety of different section sizes and thicknesses to suit loading requirements and different block thicknesses.

Ideal for use where smaller cavities restrict the use of channel section (WPC type) windposts, it is worth noting that your selected section size should ensure that the return leg does not impede the outer skin.


Tie slot holes are provided at 225mm vertical centres to both windpost legs to suit coursing and supplied windpost ties.
