1.1 Getting a precise and accurate measurement is the first step to a perfect shutter.
Always measure with a new metal or laser tape measure
Always measure twice
Always measure to the closest mm
Measure all windows, even though they appear to be identical
There are three types of frames, L Frame recessed (in) fit, Z Frame recessed (in) fit and L Frame (Out) face fit.
1.2 Determine the squareness of window
Measure diagonally from corner to corner.
Should the difference between the two diagonals be greater than 6mm, Fact fit L or recessed Z Frame fits is highly recommended.
1.3 Measuring recessed (in) L and Z Frame fit
Width – take three measurements at the top, middle and bottom of the window opening.
Drop – take three measurements at the left, center, and right of the window opening
For recess fit provides the smallest width and height measurement.
1.4 Measuring L frame Face Fit (out).
Width – take three measurements from the edge of the architrave to the edge of the architrave at the top, middle and bottom on the window frame.
Drop – take three measurements from the top of the architrave to the bottom of the architrave at the left, center, and right of the window opening
For Face fit (in) L frame, provide the largest width and height measurement.
Make sure the depth of the window is big enough for the frame that you are chosen.
You need at least 25mm of flat surface to mount your shutter frame. If the architrave is over 70mm, then 65mm ML (medium L) frames are needed. otherwise SL (standard L) frames work better.
2.1 How To Measure Your Mid Rail Position
Mid rails provide strength to your shutters and allow you to operate the top blades independently from the bottom blades. The most common placement for a mid-rail is in the exact centre of the panel. It is also common to place the mid rail at a natural break.
For recessed fit L or Z Frame, measure from the bottom of the inside of your window frame to the center point of the desired location of the mid rail.
For face fit L Frame measure from the bottom of the architrave to the center point of the desired location of the mid rail.
Customers are agreed to give up warranty claims if panels over 1800mm for basswood and 1600mm for PVC without mid rails. Extra charges may apply if more than one mid rail is needed within 1800mm.
2.2 How to measure your T-posts position
The maximum individual Panel Width is 950mm for basswood and 750mm for PVC. For larger windows T posts can be used with any frame type where the size of the window requires three, four or six panels etc. They are used to divide windows vertically to match window design and cover large spaces.
When ordering your shutters, you can choose Standard Panel widths – all panels are made equal sizes or ‘Custom’.
Below are measuring instructions if you choose custom sizes.
2.2.1 Recessed (In) fit – L Frame & Z Frame
T-Post 1 = Inside edge of window frame to centre of first T-Post
T-Post 2 = Inside edge of window frame to centre of second T-Post
2.2.2 Face (Out) fit – L Frame
T-Post 1 = Outside edge of architrave to centre of first T-Post
T-Post 2 = Outside edge of architrave to centre of second T-Post
3. Number of sides of the frame
Shutters with frames have 3 or 4 sides, which will be noted in order sheet, All of frames can be made in three or four sided frames. Most common is a four-sided frame.
LRBT stands for Left, Right, Bottom and Top frames.
4. Notes of security depth
4.1 Min security depth required when the shutters are inside mounted.
4.2 Min security depth required when the shutters are outside mounted.
* For some circumstances, Window depth can be less than 50mm by using a mid-rail at the position of hand bar. If there is a winder at the bottom of window blocked the bottom frame, 3 sides frames (no bottom frame) is the option.
