Overpanels

Features:

  • Dimension excludes the required stop
  • A 12mm deep planted stop is adequate for single acting frames whilst double acting frames may be scalloped or square
  • All door frame timber must be joinery quality, free from knots, splits and checks
  • Frame joints may be mortice and tenoned, mitred, half lapped or butted and with no gaps

Special Features:

  • All jointing methods require mechanical fixing with the appropriate size ring shank nails or screws
  • The door frame (MDF or timber) may be entirely clad in 2mm thick PVC sheeting for use with leaves either with or without 2mm thick facing material
  • Hinge fixings should be fit for purpose.

Based on the testing conducted for this design and Exova Warringtonfire’s general experience of testing both door frames and glazed screens (where the char rate of the timber increases as a result of charring from two faces simultaneously), solid timber frames may project a maximum of 18mm from the structural surround, providing one of the two frame material specifications is met.
