WINDPOSTS ARE NEEDED FOR BI-FOLDING DOORS

When designing large openings we have builders question the engineering drawings constantly about "do we really need to install wind posts?". It can get quite frustrating sometimes as it's nearly a routine question on 35% of the projects we carry out for our clients which have large openings. We tend to find that the builders who do not say anything are the more experienced builders as they have been used to installing wind posts for the past 6+ years on all projects for various engineers who implement this design. This article is to give a small brief on why Wind Posts are needed for large opening such as folding doors or bi-folding doors which are becoming the norm in extension designs these days.

WHY THE WIND POSTS? DO WE REALLY NEED THEM FOR OR BI-FOLDING DOORS?

THE SIMPLE ANSWER IS YES UNFORTUNATELY FOR THE LARGER OPENINGS IT IS NEEDED

Wind posts (also spelt "windposts") are specially designed lengths of steel designed to provide lateral support to walls of block and brickwork in typical extensions. They are supplied with brick ties which enable them to be fixed into cavities with ease making walls much stronger. Builders do not like the installation of wind posts because of the fabrication needed and the tricky installation in some instances. (having one beam sitting on bricks is easier attitude)

Wind posts would be used for example in the cavities of the walls used on either side of bi-fold or concertina type doors so that the entire end of the building can be glazed without the need for wide masonry returns on either side of the doors. This enables a much wider opening to be achieved. Wind posts are bolted to the underside of the steel beam which spans the width of the opening. Please see the details below for reference.

WINDPOST FABRICATION DETAILS

Wind posts are typically made from stainless steel or galvanised steel, and are manufactured to order so that they fit perfectly. Holes in the sides of the wind posts are pre-cut so that the wind posts can be tied into the walls, and a wide range of base and head fixings are available to suit all requirements - e.g. for bolting to a steel lintel at the top and bolting to concrete footings at the base.
