With regulations in place since June 2022, trickle vents are a mandatory requirement for most installations (some homes may be exempt within conservation areas or listed buildings, this exemption should be applied for as part of your planning process). The dedicated trickle vent cover conveniently hides the vent from view so the stunning sightlines of the windows and doors isn’t compromised. With colour matching capabilities, they are designed to fit with The Residence Collection. And it doesn’t stop there, the trickle vent also acts as a head drip to divert water away.
