WINDPOSTS ABOVE BIFOLDING DOORS: ENGINEERING INSIGHTS BY KUN ARCH
In the realm of designing expansive openings, the necessity of windposts often raises queries from builders. At Kun Arch, we frequently encounter questions like, “Is it truly imperative to incorporate wind posts?” This common inquiry, posed in approximately 35% of our projects featuring substantial openings, prompts insightful discussions. Notably, experienced builders, familiar with wind post installations spanning over six years, tend not to question this crucial element. This discourse aims to provide a concise overview elucidating why wind posts are indispensable, especially in the context of expansive openings like those accommodating folding or bi-folding doors—a prevailing trend in contemporary extension designs.
WIND POSTS IN CONSTRUCTION: VITAL FOR BI FOLDING DOORS—INSIGHTS FROM KUN ARCH
In the context of larger openings, particularly those accommodating bi-folding doors, the query often arises: Are wind posts truly indispensable? The unequivocal response is affirmative, unfortunately so, especially for larger openings. Wind posts, meticulously crafted steel components, play a pivotal role in furnishing lateral support to block and brickwork walls—a common requirement in standard extensions. Equipped with brick ties for facile cavity installation, they significantly bolster wall strength. Despite their structural benefits, builders occasionally express reluctance due to the intricate fabrication process and the challenges posed during installation—opting for a simpler beam-on-bricks approach.
UTILISING WINDPOSTS IN BRITISH ARCHITECTURE: A KUN ARCH PERSPECTIVE
In British construction, wind posts find application within wall cavities flanking bi-fold or concertina doors. This strategic placement eliminates the necessity for expansive masonry returns on either side of the doors, facilitating the creation of broader openings. These posts are affixed to the underside of the steel beam that spans the opening width. For specific details, refer to the information provided below.
Commonly crafted from stainless or galvanised steel, wind posts are bespoke manufactured to ensure precise fitting. These posts feature pre-cut holes on the sides, facilitating seamless integration into walls. Offering versatility, an array of base and head fixings caters to diverse needs, whether bolting to a steel lintel at the top or securing to concrete footings at the base.
