When starting a new building project, a renovation or updating a property for a new use, there are certain aspects that need to comply with the Government’s Building Regulations. The doors available on our website all mention what ‘part’ they comply with, so here we explain what each means.
Part M of the Building Regulations refers to accessibility for disabled persons. This is to ensure ease of access and mobility around a building. This usually means wider door openings for wheelchair access, and specifically placed door handles and glazing.
This regulation relates to the energy efficiency of a property, primarily to limit heat gain and loss. A door that complies to Part L means it is fitted correctly with no gaps, it is of the correct thickness, and the correct materials have been used. The thermal efficiency of a door needs to have a minimum U-value of 1.8W/(㎡K).
Building Regulation Part E stipulates requirements covering sound control and reduction. In certain instances in dwellings, for example when used in entrances to flats or apartments, doors are required to demonstrate an appropriate decibel reduction value.
Doors complying with Building Regulations Part B have been formally tested as a fire resistant barrier for a defined period of time, most commonly up to 30 or 60 minutes. When correctly installed, fire doors offer protection of escape routes for occupants and contribute to maintaining the fabric of the building under fire conditions.
