Glazpart Bifold Vent now in stock at Window Ware

Leading fenestration hardware distributor Window Ware has announced the immediate stock availability of the new Glazpart Bi-fold Trickle Vent, engineered specifically to eliminate the aesthetic and operational challenges posed by ventilation requirements in modern aluminium bi-fold doors.

For years, fabricators of premium bi-fold door systems have struggled to integrate standard, bulky trickle vents without compromising the door leaves’ ability to stack and fold flat or detracting from slim sightlines. This new, low-profile solution directly tackles these mechanical and aesthetic challenges while guaranteeing compliance with Approved Document F (Part F).

The Glazpart Bi-fold Vent is purpose-built for minimal intrusion. With an external protrusion of just 2mm and an internal protrusion of 6mm, the design ensures door leaves can concertina neatly without fouling.

Rob Vaughan, Product Manager at Window Ware, commented: “The design trend for large, seamless glazed installations like bi-fold doors is hugely popular, but it creates a compliance headache for manufacturers. This new vent eliminates that conflict. It’s an aesthetically superior solution that protects the product’s key selling points – the view and the fold – while offering a quick, compliant route to market.”

Designed for efficiency on the production line, the vent features a clip-on system that fits neatly into a standard 16mm rout directly on the door leaf. This removes the need for bulky ‘knock-on’ profiles and reduces fabrication time.

Delivering 2700 mm EQA each, these vents easily address the minimum ventilation requirements per habitable room of current Building Regulations. Only three vents per bi-fold are needed for multi-storey dwellings (8000 mm2 EA) and four vents per bi-fold for single-storey dwellings (10000 mm2 EA). This efficiency in both specification and installation simplifies Part F compliance for fabricators.

The Glazpart Bi-fold Trickle Vent is now in stock at Window Ware in standard White, Black, and Anthracite Grey, with bespoke colour options available on request.

Window Ware has been successfully serving the window and door industry with leading brand hardware, tools, and consumables since 1987, helping to ensure fabricator production lines keep moving and trade counter shelves stay stocked.
