Ventilation Testing Services

Ventilation Testing Services

At Airtight Testing Staffordshire, we provide ventilation testing throughout the UK which are able to be conducted alongside any of our other on-site testing services.

We offer ventilation tests throughout the UK and these can be conducted alongside any of our other on-site tests.

Extract Flow Rate Testing

Part F of Building Regulations is central to ventilation testing requirements for residential new builds. Crucially, part F states that all new ventilation systems installed in residential new builds must be tested upon completion.

This test is carried out to ensure that the specified design standards of extract and air flow rates for your build are achieved. Ventilation testing should be undertaken by BPEC qualified engineers using UKAS calibrated equipment.

Why Do Properties Require Ventilation Testing?

Ventilation testing is incredibly important for all dwellings because, without proper ventilation, a property is likely to have problems with mould, condensation and damp. When proper ventilation is ensures, a building’s air quality is improved and the risk of health problems relating to air moisture is removed.

As air tightness has increased broadly across the country, it is more important than ever to get the right amount of ventilation. Ventilation testing guarantees this and protects the areas of a property where moisture can build up, such as bathrooms and kitchens.

Types of Ventilation Systems

Within part F of Building Regulations, there are 4 types of systems that are discussed. Ventilation testing must be carried out on types 1, 3, and 4. These types of ventilation system included within part F of Building Regulations are as follows:

 

Type 1 Ventilation Systems

Within this type of ventilator system are intermittent extract fans with background ventilators, along with extractors fans in kitchens, toilets, bathrooms, and trickle ventilators on windows. Intermittent extract fans are those most commonly found in homes.

 

Type 2 Ventilation Systems

This kind of system is uses passive stack ventilation. This means that it uses a combination of cross ventilation, buoyancy (warm air rising) and the venture effect to ventilate. This type of system is very rarely installed because of its weather dependency.

 

Type 3 Ventilation Systems

This type of ventilation system uses mechanical extract ventilation (MEV). This kind of system can either be a whole house system or a localised system for individual rooms. This system will feature multiple ducts that run from a constantly active unit to wet rooms (kitchen, WC, bathroom) to continuously extract stale air. When these wet rooms are in use, the system will boost itself to extract a larger volume of air.

 

Type 4 Ventilation Systems

Type 4 ventilation systems use what is called mechanical ventilation heat recovery (MVHR). This is similar to Type 3 but also supplies fresh air to other rooms, such as bedrooms, dining rooms, and living rooms. This system also utilised heat extracted from stale air and keeps it within the central unit to, in effect, heat fresh air from outside before it is supplied to the house.

 

What is Needed for a Test?

To carry out our ventilation testing services, we will need the SAP calculations, details of the property’s ventilation system, its design, and floor plans of the dwelling. The system must be fully installed and operational.
