5" Core Vent Cavity Ventilator Anti Draught White Cowl for Gas Appliances

Product Information

The external cowl minimises uncomfortable draughts, reduces noise and light from outside the property and acts as a barrier against wind driven rain whilst providing a free area of 100cm² and is available in both brown and terracotta. Noise Reduction: Acts as a sound baffle, absorbing and reducing external noise, creating a quieter indoor space.

Another solution, which needs designing in from the start, is passive ventilation. What is Uncontrolled Ventilation? One of the key benefits of MVHR is improved air quality. Plus, the removal of pollution and airborne allergens, such as pollen, means such systems are highly beneficial for allergy suffers.

The kit includes a cowl vent for exterior use, a louvre grille for inside, a 350mm length of pipe duct and an optional anti-draught baffle. This baffle reduces the airflow and also the feel of a draught through the vent. The vent can easily be fitted in both refurbishment and new build situations with the use of a 5" (127mm) diameter core drill. Internal doors must be open to allow the passage of air to move through the home, enabling cross ventilation

The Louvre fits on the internal wall and, similarly to the cowl, reduces draughts, noise and light penetration, while providing a free area of 100cm², it is only available in white. The Stadium BM725 anti-draft vent should be installed as close to the appliance as possible and should be fitted as high up as possible. This ensures the cold air being drawn in mixes with the warm air at the top of the room.

The Manthorpe 5" Core Drill Vent G900 is designed for use when ventilating a gas appliance, but can also be used for general through wall ventilation. This 5 inch 13kW STADIUM Stadium anti-draft vent has a built in anti draught baffle which is designed to reduce or stop wind blowing through the vent by its unique duct design. Install the Stadium anti-draft vent with a 127mm (5″) core drill. Unlike some other core drill air vents an extension tube is supplied with this core drill ventilator for walls over 9 inches up to a maximum of 23 inches. Anti-Draft Baffle: Included for your convenience, the anti-draft baffle minimises unwanted air currents and draughts, maintaining atmosphere.
