Building regulation for windows
Your selected installer should be registered under the FENSA scheme considering the building regulation. Other than that, you must attain the certificate from the local authority confirming that the installation is approved under the building regulation.

- Safety glazing: Safety glazing should be provided to glass that is in any critical area. Safety glazing is based on ensuring that injuries could be avoided due to the occupant colliding with the open windows. It is also based on the windows positioning and glass panes marking.
- Ventilation: The ventilation regulation is based on a factor such as steam produced in any area. It depends on the size, usage, and type of the room. For example, a room with more steam production should be provided with a high level of ventilation.
- Means of escape: According to the new replacement windows regulations, the opening should be sized to provide the potential to escape. The mean of escape for the newly installed window should be based on an extension or existing dwelling.
- Unprotected areas: According to the new replacement windows regulations, external windows need to have fire resistance and self-closing to reduce the fire spreading risk between the adjacent properties.
