Timloc Aero Core Through-Wall Vent Set with Baffle – Brown – 127 x 350 (1pcs)

The Timloc brown through-wall vent set gives you everything needed to create a neat, functional ventilation opening through an external wall in one go. Inner grille, outer grille, the core sleeve — it’s all here. Designed for background ventilation and suitable alongside heat-producing appliances such as gas fires and solid fuel stoves, this is the kind of product that makes a fiddly job straightforward. The baffle built into the system reduces cold air draught without blocking the airflow you actually need, which is the whole point of the thing.

Through-wall ventilation is one of those details that gets missed until it causes a problem. Condensation, appliance underperformance, Building Regulations sign-off — ventilation touches all of it. The Aero Core vent set is designed to comply with background ventilation requirements and is particularly relevant where a heat-producing appliance demands a dedicated air supply. The brown finish suits standard facing brickwork and blends reasonably well with most brown and buff mortar tones without standing out awkwardly.

Where the Timloc Aero Core Through-Wall Vent Gets Used

This vent set is used in new build and refurbishment work wherever a through-wall air supply is needed. Builders fit them during cavity wall construction before the outer leaf goes up, or they can be core-drilled into existing walls post-build. The sleeve bridges the wall thickness and the two grilles finish the internal and external faces cleanly. You’ll find them specified on jobs with solid fuel appliances, gas fires, and woodburning stoves where the install requires a dedicated combustion air supply, as well as in rooms where background ventilation is required under Part F of the Building Regulations.

Baffle Function

The baffle inside the sleeve deflects incoming airflow so cold air doesn’t travel straight through and create a draught at floor level. It’s a small detail that homeowners notice — and appreciate — once the appliance is in use. It doesn’t restrict the overall ventilation rate, it just stops the vent from feeling like a letterbox in January.

The Timloc Aero Core range is a well-established choice among bricklayers and builders merchants alike. These sets are supplied as a complete kit, so there’s no hunting around for matching components from different product lines. At this price point and with next-day availability, it makes sense to add a couple of spares to the order if you’ve got more than one opening to complete.
