The design of the Link Vent MK II Trickle Vent benefits from aerodynamic features which direct the air flow efficiently through the vents pathway - the canopy extends only 25mm. It has been developed to meet the minimum requirements of the building regulation Part F1:2021.

Options are available to ensure compliance for both 10mm and 13mm slot height requirements. The design of these Glazpart trickle vents allow enhanced air flow for their size, meaning in many scenarios, fewer vents are required to rout and fit making installation faster and keeping production costs down.

This Glazpart trickle vent has one of the highest decibel ratings on the market for a non-acoustic vent. Improved Db reduces noise to new levels of performance, especially in the closed position. The aesthetically pleasing and patented design helps to reduce the visibility of the trickle vent on a window.

It is available in a large range of solid colour or wood grain finishes - internal and external parts can be bought separately for flexible colour choice. The vents are through moulded meaning the colour won’t scratch or peel off. Canopies can be vacuum foiled to match embossed Linear wrapped profiles and the vents can be sprayed to any RAL colour.

This Glazpart trickle vent has no end caps and is supplied with the fixing clips fitted - you can push fit the vent into place within seconds. The clips automatically centre the vent in the rout, ensuring it is fitted level. If you prefer to screw fix your trickle vents, just pop out the fitted screw caps before fitting and fix as normal.
