Ventilation building regulations have recently changed in England and Wales.  Although this vent supports compliance, we would urge you to read our handy guide before you purchase which summarises the new requirements. 

Glazpart has taken trickle vents to a whole new level with the Link Vent Mk2 4000! It boasts a compact, low-visibility design with a unique closure plate which optimises and controls airflow to achieve 4000mm² EA, as well as cuts out noise and firmly shuts out the elements. What's more, this trickle vent is a master of camouflage - available in a wide range of colours including trend tones Chartwell Green and Anthracite Grey, with realistic woodgrain finishes and RAL colour matching on request. Great news for fabricators and installers: this window vent, is quick and easy to fit (available with screw or clip fixings) and super robust with no end caps to lose or break!
