Yale has introduced a range of trickle vents in response to the changes to the revised Approved Document F of Building Regs due to come into force later this year.

Technical Director Grant Stratford explained the move: “Trickle vents are a requirement under the Building Regulation, England and Wales Approved Document F1 and Scottish building regulation 3.14.”

Named, SlotVent, the range offers a choice of three variants – 2500EA (Equivalent Area), 4000EA, and 5000EA – each providing a different level of ventilation, depending on requirements.

The product is made up of an internal vent that can be tilted 30, 60, or 90 degrees and includes the option of a foam gasket that reduces noise and draughts; as well as an external hood and a fly screen for the over-frame.

The vents are available in a range of colours from Black and White to Agate Grey, Chartwell Green, and Irish Oak – inners and outers can be ordered as a set or separately to suit the window aesthetics and specification.

They are attached to the window using pre-fitted clips, or can be fixed using the screw-holes provided in the clips.

All products in the SlotVent range have been tested at BRE in accordance with EN13141-1:2019 (residential building ventilation) and BS EN ISO 10140-1 (insulation against airborne sound).

Grant Stratford continued: “The SlotVent range offers fabricators and installers a solution that not only ensures they meet the regulations but provides a series of features and capabilities that genuinely enhances the window, making it a more attractive proposition to customers.

“The range comes with our 10-year mechanical guarantee, as you expect from Yale which means that we will replace the product free-of-charge if it fails to function correctly due to manufacturing defects in that period.”

The changes to the regulations were confirmed by the government last month as part of its continuing target of reducing carbon emissions in homes.
