L Section Windpost

L Section Windposts are designed to minimise intrusion into the cavity. One leg of the post is built into the inner leaf blockwork and tied with wall ties to both leaves to minimise any possible movement of the structure

Windposts are supplied with specifically designed base / upper connections and fixings. The upper connection allows for shrinkage or vertical movement of the building frame. They are also supplied complete with the correct type and number of wall ties which will be dependent on the type of post used and the cavity width.
