Before Installation Guide
Do You Need a Double Frame?
Before installation, it is important to check your existing window frame and handle clearance. Depending on the product and window design, an additional double frame may be required to provide enough space for the system to operate correctly.
Before You Measure
Not Every Window Needs a Double Frame
Whether a double frame is required depends on the product you are installing, the design of your existing window and how far your window handle protrudes.
When is a Double Frame commonly required?
A double frame is commonly required for 2-in-1 systems or blinds when the existing window handle protrudes into the space required for installation.
The additional frame provides extra clearance so that the window handle and the installed product can function normally without interfering with one another.
For mesh-only installations , a double frame is generally not necessary.
Usually No Double Frame Required
For a mesh-only system, the mesh is generally opened when you need to operate the window. Once the window is closed, the mesh can be closed again. Therefore, it will generally not interfere with or affect the window handle.
Handle Clearance Must Be Checked
For 2-in-1 systems or blinds, the installed product may sit closer to the existing window. If the window handle protrudes too far, additional clearance may be required. This is when a double frame may be recommended.
Measurement Guide
How to Check Your Window
Watch the video to see how the window frame and handle clearance should be measured before installation.
The overall window size is not the only measurement we need to consider. It is also important to check how far the handle protrudes and how much space is available between the existing window and the new system.
Step-by-Step
What You Need to Measure
Follow these measurements to help us understand your window configuration and determine whether additional frame clearance may be required.
Step 01
Check the Centre Clearance
Measure the width around the centre section of the window where the handle is positioned.
This helps us check whether the window handle may protrude into the installation area and determine whether additional clearance or a double frame may be required.
Step 02
Measure the Handle Protrusion
Place the window handle in its locked position and measure how far the handle protrudes outward from the window frame.
This measurement helps determine whether there is sufficient clearance for a 2-in-1 system or blind.
Step 03
Measure the Window Height
Measure the full height of the window frame from the bottom installation surface to the top.
The height needs to be measured as accurately as possible to ensure that the finished system fits correctly.
Step 04
Measure the Window Width
Measure the full width of the window frame across the intended installation area.
Just like the height measurement, the window width should be measured carefully and accurately.
Step 05
Check the Centre Height
If your opening consists of two separate window sections, measure the height at the centre as well as the left and right sides.
This is especially important when there is concrete around the window, as the centre height may be slightly different from the measurements at the sides.
Why Do We Check More Than One Measurement?
Window openings are not always perfectly even. The left, centre and right sections may have slightly different measurements, especially where concrete, plastering or existing window frames are involved. Checking these areas helps us better understand the installation conditions before production.
Good to Know
Double Frame Is About Creating the Right Clearance
A double frame is not automatically required for every window. It is mainly used when additional clearance is needed between the selected product and your existing window handle. For mesh-only installations, it is generally not required because the mesh can be opened whenever the window needs to be operated.
