Underfloor & through wall ventilation

Ventilation in buildings is vital. Properties need natural ventilation to prevent stale air and dangerous gases from developing.

At Timloc, we offer a range of underfloor and through wall solutions that provide passive ventilation into spaces. They are quick and easy to install and comply with Building Regulations, NHBC stipulations, and British Standards.

Our through wall products include a range of vents and accessories, which allow cross ventilation and wind-induced ventilation to pass through external walls and bring air into a room. This not only aids general background airflow, but it can make a safer environment for spaces with heat-producing appliances.

Timloc’s underfloor products provide ventilation openings within suspended floor voids to create a flow of fresh air and prevent condensation, stagnant air and issues with radon and methane gas.

Underfloor Ventilation

If a building uses a suspended ground floor, it is important to provide underfloor ventilation into the void. 

This prevents condensation, removes stagnant air, and is vital in areas where radon or methane gas may pose a problem.

Airbricks and External Cowls

An effective, robust and durable airbrick ventilator presenting an equivalent area of 6170mm² (free area of 6500mm²).

Ideal for underfloor or room ventilation applications when used with the Timloc telescopic underfloor vent or cavity sleeve.

Through Wall Ventilation

Through-wall ventilation provides passive ventilation through external walls into habitable rooms. 

It is important to differentiate between:

• Wall vents which are required to provide general background ventilation
• Wall vents that provide air into a room which contains a heat-producing appliance, such as a central heating boiler or gas fire

Timloc offers a range of through-the-wall vent solutions, for both general background ventilation and to provide ventilation to heat-producing appliances in both new-build and retro-fit projects.
