In keeping with the growing trend, earlier this year, Glazpart( the leading trickle vent manufacturer) introduced a new bi-fold door trickle vent, simply called the“ Bi-Fold Vent”. At the two major glazing industry events this year, namely Glazing Summit and FIT Show where the Glazpart team gave customers demonstrations showing how the new Bi- Fold Vent works within a bi-fold door system.

Manufactured specifically for aluminium bi-fold doors this shallow height( slim) vent is designed to work within the low hinge stack heights when the doors in a bi-fold system are in the open position – it has unique low-profile louvred canopy design combined with a low profile vent to allow both the internal vent and louvered grille clip in to easily sit between the open concertinaed door leaves.

The vent is designed for compliance to the building regulations with the independently tested equivalent area, it sits in a 16mm rout and in many cases, can be located directly into the

door leaf or frame, removing the need for expensive additional“ knock on” or extended profiles. With an EQA of 2700EA a 3-panel door meets the background ventilation regulations for the room.

The tried and tested clip design sits perfectly in the low-profile chassis allowing the split closure plates to direct the air away from occupants.

aluminium is a material in which Glazpart is taking a greater interest

The internal closure plates of the Bi-Fold Door Vent clip onto a uniquely designed low prolife chassis which in turn clips within the aluminium profile, so you only have the height of the lids protruding above the profile. The chassis can be supplied in either white or black dependant on the colour of the patented closure plates with their innovative vertical closure plates.

The external section has a new louvered design, to give the

minimum amount of protrusion from the face of the profile. The louvred flyscreen sits beneath the reveal giving additional protection from the elements.

Moulded from high quality virgin ASA, Bi-Fold Vents are highly temperature and colour stable when compared to UPVC. Initially available in White, Black and Anthracite Grey in standard sets, bespoke and matching colours will also be manufactured

With a growing number of fabricators using aluminium in their manufacturing, combined with an increase in homeowners’ demand, aluminium is a material in which Glazpart is taking a greater interest. In October 2024, Glazpart joined the Council for Aluminium in Building( CAB) to further expand the Glazpart team’ s knowledge and understanding of aluminium as a building material and how it fits within their own award-winning product portfolio and future product development.

For over ten years, Glazpart has consistently invested in state-ofthe-art machinery and tooling to provide a vast spectrum of colours and finishes. Glazpart is an approved colour paint sprayer and offers all standard RAL( European Colour Systems) and BS( British Standards) colours on an appropriate base colour vent with a gloss / sheen level to the powder coating. The company also has a specialist colour matching service that can match non-standard colours and supplied colour samples. With all this in the locker, Glazpart

is in pole position to supply vents in practically any colour or decorative finish for any aluminium window or door profile.

Like aluminium itself, the Glazpart Link Vent colours are extremely stable and durable with the vents holding their colour through constant exposure to the elements of weather, without noticeable fading.

Dean Bradley summarised,“ The Bi-Fold Vent is a great addition to our trickle vent range. It not only meets regulatory standards and fits perfectly within the profiles of aluminium bi-fold doors but it also has an easy opening and closing mechanism for greater control of air flow. The product is in now in full manufacture and is already proving popular with Glazpart customers operating in bi-fold door sector.”
