8th July 2022
There has been much going on in Parliament this week. Read on for a summary of certain topics you may have missed.
Updated Approved Document F1 – Ventilation
Building Regulation Approved Document F (AD F) has been updated for England and Wales. It concerns ventilation to maintain indoor air quality and is specific to ‘Existing Dwellings’ only. It came into effect in England on 15th June 2022, and will later come into effect in Wales on 23rd November 2022.
- Background ventilators are required in any replacement windows which are not wet rooms, if the dwelling has, or is planned to have continuous mechanical extract ventilation. The minimum equivalent area is 4000mm² in each habitable room.
- Additional background ventilation will not be required if the dwelling has, or plans to have continuous mechanical extract ventilation with heat recovery
- Additional requirements for specific scenarios include the addition of a “conservatory” or “wet room”.
- Approved Document F: Volume 1 applies to dwellings
- Approved Document F: Volume 2 applies to buildings other than dwellings
What are the potential implications?
- Increased number of ventilators
- Increased length of ventilators
- Property / window design specific with a requirement for a ventilator to be in the sash and the head
- The addition of window frame extensions to clear plaster lines, increased head rail size and/or a change of design
What if the existing design won’t be able to achieve regulation compliance?
- Alter the design so that it complies with regulation
- Specify additional vent-to-head (only one window within a wet room, two smaller vents required due to size of the window. Additional vent added to head, dependent on plaster lines a frame extender may be required)
- Specify over frame / glass vent
- Install vents to the size and quantity as is technically feasible to achieve as close to the requirements
