One of the key considerations when manufacturing aluminium windows and doors is ventilation. Since the changes in building regulations in July 2022, compliance with building regulations as set out in Approved Document F( means of ventilation) is now critical for companies replacing windows or doors made of any material including aluminium.

No matter which situation when replacing windows and doors, installing trickle vents on doors and windows is the most practical, viable and economical ventilation solution.

Over the last decade, Glazpart’ s Link Vent has become the trickle vent of choice for window and door companies.

To ensure compliance with Building Regulations, the Link Vent range sizes include 5000, 4000 and 2500 EQA and can be fitted to aluminium doors and / or frames.

The clever design of the Link Vent makes it simple to install and user friendly for both opening and closing- the innovative closing action allows the closure plate to be positioned so that it reduces draughts by directing air away from occupants.

Smart design, easy fitting, and functionality are fundamental features but it is the huge choice of colours and decorative finishes that sets Glazpart apart from the competition. The vent’ s colours and finishes can be perfectly matched to blend in with the overall design and look.

The colours / finishes are also extremely stable and resistant to UV, meaning the vents hold their colour in extreme weather conditions and constant exposure to the elements of weather, without noticeable fading.

In 2025, Glazpart launched the innovative Bi-Fold Vent 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 a 2700 EQA( per vent), a 3-panel door meets the requirements for background ventilation.

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.

The internal closure plates of the Bi-Fold 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 can also be manufactured( dependent on demand).

Less than 12 months since its launch, the Bi-Fold Vent has already been shortlisted for several industry awards for its technical innovations.
