How to Measure for DIY Double Glazing

Ordering your DIY Double Glazing Kit can be a daunting process if you’re unfamiliar with the joinery jargon. We’ve tried to make it easier for you by providing the instructions below.

If you get stuck, try referring to our Measurement Form for help, or get in touch. Otherwise, if you’re based in Wellington, you can streamline the process by considering our measuring service.

For DIY Double Glazed Doors

To order via our store, we need 7 pieces of information to correctly price and manufacture your doors. These are:

  1. The type of timber you would like,
  2. The opening height & width,
  3. The stile & top rail width,
  4. The bottom rail height,
  5. The open-out angle,
  6. Whether the door is external or internal, and,
  7. The door profile type.

Type of Timber

We currently manufacture doors with three types of timber: malaysian kauri, cedar, and pine.

Use pine if your doors are painted. Our pine doors are delivered primed ready for the finishing coat. If your doors are cedar, it is best to stick with this throughout your home. Malaysian kauri is a good alternative for any other wood type, as it can be stained to match your existing doors.

Opening Height & Width

To Measure Width:

Measure between the vertical sides at three points: top, middle and bottom of the door opening. Use the largest of these three measurements to order the door.

To Measure Height:

Measure from the high point of the sill of your door (the surface closest to the inside of the door) to the top of the door opening. Make three measurements: one at the left side, one at the center and one at the right side of the door. Use the largest of these three height measurements to order the door.

Stile & Top Rail Width

This is the width of the timber on the two vertical sides, and the top rail.

Bottom Rail Height

This measurement is simply the height of the bottom horizontal of the door.

Open-Out Angle

If the door is externally-facing and opens outwards, it will need a slope on the bottom rail to match the slope of the external sill. If it is an interior door, or an externally-facing door that opens inwards, you don’t need to worry about this.

External or Internal

Simply, is one side of the door on the outside of the house or not.

Profile Type

In joinery, the ‘profile’ refers to the moulding of the timber on the inside of the frame. For online ordering, we only support two of the most common types of profiles: ogee or sash. The sash profile is a simple linear slope, whereas the ogee is more intricate, detailed below.
