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 Windows

To order via our store, we need 5 pieces of information to correctly price and manufacture your windows. These are:

  1. The overall size category your window falls under,
  2. The type of timber you would like,
  3. The measured width & height of the window,
  4. The bottom rail height,
  5. Whether the window opens, or is fixed, and,
  6. The window profile type.

We have created a video to help guide you through this process, or continue below for a written explanation.

Size Category

We have four size categories for windows:

  • Up to 600mm x 600mm,
  • Up to 1200mm x 600mm,
  • Up to 1200mm x 1500mm, and,
  • Up to 1200mm x 1800mm.

To know which category your window falls under, you need to know the measured height and width. Once you know this, simply select the category that your window falls under. For example, a window measuring 1150mm x 750mm would fall under the category up to 1200mm x 1500mm. This is because one of the measurements (750mm) is greater than the cut off point for the previous category (600mm).

Type of Timber

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

Use pine if your windows are painted. Our pine windows are delivered primed ready for the finishing coat. If your windows 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 windows.

Measured Height & Width

To Measure Width:

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

To Measure Height:

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

Bottom Rail Height

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

Opening or Fixed

Can you open your window, or is it fixed? We supply opening windows with stainless steel hinges.

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.
