The process of obtaining building permits for residential construction frequently requires the installation of doors manufactured to withstand fire for a fixed period of time.  Builders Finish supplies various kinds of doors which carry a "20 minute" label.  These doors are engineered by the manufacturer to withstand fire for 20 minutes.  Other labeled doors, engineered to withstand even longer periods of fire exposure are also available.  For more information, and other regulations which apply to these doors, call 714-540-7117.

  The most common types of doors ordered with
a 20 minute label are: moulded hardboard,
plain slab, and wood veneered.
