Do I have the right style of window for Perfect Fit Shutters?
Perfect Fit shutters are installed using brackets that slide under the rubber seal in your uPVC window or door. Before ordering, there are three quick checks to confirm your window is suitable.
First, gently slide a credit card between the rubber beading and the glass. If it slides in at least 10mm, the bracket can grip securely. If not, Perfect Fit shutters will not be compatible with your window.
Second, measure how far the rubber beading overlaps onto the glass from the frame edge. If it’s more than 6mm, Perfect Fit Shutters will not be compatible with your window.
Third, check for any obstructions around the glass - such as handles or vents. Measure from the edge of the visible glass to the obstruction. You need at least 25mm of clear space on all sides, as the shutter panel extends beyond the glass onto the frame. If any side has less than 25mm, Perfect Fit shutters will not be suitable for your window.
Measuring Perfect Fit Shutters Step By Step
What tools you’ll need:
- Steel tape measure
- Pen or pencil
- Paper
- Credit or debit card
Step 1
Measure the Width
Measure between the inside edges of the rubber beading in three places: Top, Middle, Bottom. Use the smallest measurement.
Do not include any of the rubber beading or seals.
No deductions are needed; use your exact measurement when ordering.
Step 2
Measure the Height
Measure between the inside edges of the rubber beading in three places: Left, Middle, Right. Use the smallest measurement.
Do not include any of the rubber beading or seals.
No deductions are needed, use your exact measurement when ordering.
Step 3
Measure for a mid rail
A mid rail is a horizontal bar that divides the shutter into upper and lower sections and provides stability. It is required for shutters taller than 1500mm.
Measure from the bottom of the glass to where you want the mid rail to sit (centre point). It must be at least 275mm from both the top and bottom, but is usually placed centrally.
Important: The mid rail location may be adjusted by up to 45mm during manufacture to align with the slats.
Step 4
Measure the frame depth
Your frame depth is the depth of your window beading. We need this information so that we can send you the right bracket size for your window. Our available sizes are: 18mm, 20mm, 22mm, 24mm, or 30mm.
To help do this, place a credit card across the corner of the frame, so it’s overlapping the glass. Measure the gap from the glass to the edge of the card using a tape measure or ruler - this is your frame depth.
When ordering your Perfect Fit Shutter, select the frame depth that matches your measurement.
Note: If your measurement doesn’t match one of these sizes, Perfect Fit shutters may not fit securely; we recommend choosing an alternative product.
Optional Step
Measure your handle position
If your window has a handle, you’ll need to add a handle cut-out. When ordering, you’ll be asked for the location (left, right, top, or bottom) and the handle position.
How you measure the handle position depends on your handle location:
- Left or right handle: Measure from the bottom of the glass to the centre of the handle when in the open position
- Top or bottom handle: Measure from the left edge of the glass to the centre of the handle when in the open position
Note: Handle cut-outs are only needed for windows, not for patio doors.
