Windposts are designed to offer an alternative, cost-effective method of providing the additional stiffness that a masonry wall requires as specified by the Structural Engineer.
Windpost Types
Four types of Windposts are manufactured in a range of section sizes and steel thicknesses to withstand applied wind loadings. Base and top fixing configurations can be specified to allow for varying methods of construction and loading requirements.
U Section
U Section Windposts fit within the wall cavity and normally span between floor structures. H Section H Section Windposts serve the same purpose whilst allowing for heavy duty applications. Both U and H windposts leave the inner leaf of the cavity wall undisturbed.
H Section
H Section Windposts serve the same purpose whilst allowing for heavy duty applications. Both U and H windposts leave the inner leaf of the cavity wall undisturbed.
L Section
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.
Spine Posts
Spine Posts are generally used for internal fair-faced walls. The post is a flat plate that can be built between blockwork panels and does not protrude beyond either finished face. Posts are usually 20mm narrower than the wall width with any additional load requirements provided for by an increase in the thickness of the post. Blockwork is tied through the post, the design allowing for the inclusion of debonded movement ties if required.
Windposts Wall Ties
All Windposts are supplied with the correct number of wall ties and fixings. All wall ties comply with BS EN 845-1 Specification for ancillary components for masonry – Part 1.1.
