Timloc Aero Core through-wall vent with high rise baffle in terracotta. Designed for background ventilation and use alongside heat-producing appliances. Suits cavity and solid walls where a neat, reliable solution is needed.
The Timloc terracotta through-wall vent is part of the Aero Core range, a system designed specifically for situations where you need both background ventilation and adequate air supply to heat-producing appliances like gas fires, boilers, and solid fuel stoves. The high rise and baffle configuration gives you directional control over airflow, reducing cold draughts at floor level while still delivering the free air area the appliance or room requires.
Through-wall vents get overlooked until something goes wrong. A room that fogs up, an appliance that keeps cutting out on overtemperature, or a damp problem that nobody can pin down — more often than not, ventilation is the culprit. Getting the right product in from the start saves a lot of grief later.
Where the Timloc Aero Core Through-Wall Vent Fits In
This vent is used on new builds, refurbishments, and retrofit installs where a core-drilled or pre-formed opening through the outer leaf needs a proper finish with the right airflow characteristics. The terracotta colour suits traditional brick and tile finishes without the need for painting or additional finishing work. It sits flush, it looks considered, and the baffle arrangement means the free air isn’t just blasting straight in at ankle height.
The combination of high rise design and integrated baffle makes it particularly well suited to installations next to gas appliances, open-flued heaters, or any situation where BS 5440 or Part F of the Building Regulations comes into play. Specifiers and building inspectors will expect to see the free air area documented, so check the Timloc data sheet for the certified free area figure before sizing the opening.
A Note on the Terracotta Finish
Terracotta is one of those finishes that tends to blend into traditional brickwork better than you’d expect. It’s not a perfect match for every clay brick, but it’s a far more sympathetic choice than white or brown in most situations. Worth having a look at the colour in daylight against your brick before ordering at scale.
Supplied as a single unit, the Timloc Aero Core terracotta through-wall vent includes both the external and internal components needed for a complete installation. No separate baffle kits, no hunting around for matching parts.
Pro Tip: Always confirm the certified free air area of the vent against the appliance manufacturer's minimum requirement before finalising the core hole size, particularly on gas appliances where the installer is signing off the commissioning certificate.
Through-wall ventilators like this one are used wherever an opening through a masonry wall needs to provide controlled background ventilation. Common applications include ventilating rooms with open-flued gas or solid fuel appliances, providing combustion air to boiler rooms, and meeting minimum ventilation requirements under Part F and Part J of the Building Regulations. They are regularly specified on new build housing, domestic extensions, and commercial refurbishments where adequate air supply to heating appliances must be demonstrated. Groundworkers and bricklayers core the opening, and the vent is fitted before internal finishing.

Not suitable for: Not suitable for use as a sole ventilation solution in rooms with room-sealed or balanced-flue appliances, which draw combustion air directly from outside. Not intended for use in areas subject to prolonged standing water or direct high-pressure water ingress.
Mark and core-drill the through-wall opening to the required diameter, ensuring the hole is level and free of loose debris. The Aero Core vent components fit into the opening from both the internal and external faces, with the baffle orientated to direct incoming air upward and away from floor level. Bed the external face plate into an appropriate mortar or exterior sealant to weatherproof the joint against the masonry.
Check that the finished installation provides the required free air area for the specific appliance or regulation requirement before completing the surrounding finishing work. Internal and external faces should sit flush with or slightly proud of the wall surface for a clean finish.
Identify the correct wall position for the vent, keeping clear of structural elements and damp-proof courses
Core-drill through the wall to the appropriate diameter for the 127 x 350mm vent body
Clear the core hole of dust and loose material before fitting
Insert the vent body through the wall, ensuring correct orientation with the high rise baffle facing inward
Fit the external face plate and bed it into mortar or exterior frame sealant to seal against weather
Fit the internal grille component and check it sits flush with the internal wall surface
Verify the free air area against the appliance or regulatory requirement before signing off
What size core hole do I need to drill for this vent?
The vent body is 127 x 350mm, so you will need a core hole sized to suit those dimensions with a small amount of clearance for fitting. Check the Timloc installation guide for the exact recommended opening size, as this can vary slightly depending on wall thickness and the specific core drill used.
Is this vent suitable for use with a gas fire or open-flued boiler?
Yes, the Aero Core high rise and baffle combination is specifically designed for background venting alongside heat-producing appliances including open-flued gas fires and boilers. Always confirm the certified free air area against the appliance manufacturer's minimum requirement and current Building Regulations guidance before installation.
Does the terracotta colour fade or require painting?
Timloc manufacture the vent in a terracotta-coloured material, so the colour is inherent rather than painted on. It should not require repainting, though like any external fitting the appearance will be affected over time by weathering and the specific conditions on site. It is not an exact colour-match guarantee for any particular brick, so it is worth checking the shade in daylight before committing to a large installation.
The Timloc Aero Core through-wall vent is manufactured from UV-stabilised uPVC and designed to provide a measured free air area suitable for background ventilation and combustion air supply applications. The high rise baffle configuration directs incoming air upward to reduce floor-level cold draughts. The terracotta finish is an integral part of the moulded component rather than a surface coating.
