Overhead protection of your doors

NHS Hume Doors
Approx read time: 2 minutes

With Australia’s climate extremes, exterior/entrance doors will weather differently and timber doors are more susceptible to the elements than steel, aluminium or fibreglass doors.

Depending on your location and aspect the required overhead protection will vary, with tropical areas generally requiring more overhang than southern states. The chart below will assist in determining the size of overhead protection which will vary depending on home design and adjacent walls. Refer to the chart for dimensions A&B.

Dimension ‘C’ – subject to adjacent walls – minimum width same width as entry frame

Note: Colour choice for your exterior door will also affect weathering. Dark colours absorb heat, accelerating door deterioration, warping and bowing.

Care & Maintenance

  1. After selecting and purchasing your door, store flat in a dry, well ventilated area prior to installation.
  2. Your timber door may be affected by changes in temperature, moisture and location.
  3. Before fitting the door, all six door surfaces should be sealed initially then after installation painted, stained or clear finished with good quality products. Follow the paint manufacturer’s instructions with the correct number of coats on ALL surfaces.
  4. Light reflective colours are recommended for Entrance Doors to reduce the possibility of bow, twist or warp. Dark colours may void Hume guarantee. Semi gloss finishes are recommended. Paint with a light reflectance value (LRV) finish greater than 50 should be used on External Doors. White – LRV approx, 95 Black – LRV approx 5.
  5. Use the same colour on all six door surfaces. Different colours may cause doors to warp.
  6. Entrance Doors require overhead protection (above).
  7. Location and fitting of your door furniture depends on door construction. Honeycomb core doors have a lock block (piece of timber) located generally on the side with the Hume label and door furniture should be fitted in this location. Solid doors may have door furniture installed at any selected height, either side of door.
  8. Door maintenance is necessary for long term performance and periodic inspections are recommended. At the first signs of deterioration, your door should be properly
    refinished, making sure that all bottom surfaces of the door receive proper resealing and painting.
  9. To clean your door, use a damp cloth. Do not hose or use chemicals or abrasives on your door. Lightly oil hinges and door furniture for optimum performance.
