How To Measure Your Window for a Commercial Roller Shutter
Height Measurements:
 |
 |
|---|
Ensure you measure both sides of the window and use the largest of the two sides as your final measurement.
On Wall installation (OW)
OW is optional in its placement: to the eaves or above the window, or level
with the window, or partly in the window space, etc, to your preference.
Please note: The overall height of the
Roller Shutter is to the top of the head box, so if the head box is above the
window or door use the table below to calculate the
overall height of the Roller Shutter.
The head box increases in sizes from 180mm 205mm 230mm 250mm and
300mm
in relationship with the height; see the table
below.
Please note: On wall (OW) has greater
flexibility and is more accepting of 'out of square' windows.
Please note: When the Roller Shutter is fully open, the bottom bar of the curtain will still protrude out from the bottom of the headbox by about 30mm.
In-Reveal installation (IR)
IR is determined by the sill and above-window opening (lintel), as illustrated above.
Please note: In-reveal (IR) allows for zero margin for error in measurements.
Width Measurements:
 |
 |
|---|
Ensure you measure both sides of the window and use the smallest of the two sides as your final measurement.
On Wall installation (OW)
For OW, the overall width of the roller shutter is the window opening plus
the width of the guides.
Roller Shutter Guides: 76mm wide each, and there are two (x 2),
So, total width of shutter = width of window plus 152mm.
Please note: On wall (OW) has greater
flexibility and is more accepting of 'out of square' windows.
In-Reveal installation (IR)
IR width is determined by the window aperture at its smallest point (e.g.
the top of the window may measure 1200mm but the bottom may measure 1203mm and
the middle measures 1205mm - your measurement should then be 1200 for overall
width).
If the head box is to be fitted at the narrowest point ( as described above ) reduce the width by 1mm to 1199mm so you know that the head box will fit between the opening.
If the narrowest point is at the bottom stick to that measurement.
Please note: In-reveal (IR) allows for zero
margin for error in measurements.
Please note: That some outward opening windows and doors many not open with In-reveal (IR) installation. The guide is 76mm wide and may interfere with outward opening windows and doors; in this case On Wall installation may be your only option.
Headbox Sizes
In case you are wondering "But how far will that 'Box' thing stick
out?", the table below shows the relationship between a Roller Shutters'
size and how big the Head Box will be.
The height of the head box for the BC45 is the same as the width of the box
(i.e. 180mm box is 180mm high x 180mm wide).
| Rollershutter Height Includes Head box | Headbox Sizes |
| Up to 1460mm | 180mm |
| Up to 1920mm | 205mm |
| Up to 2530mm | 230mm |
| Up to 3100mm | 250mm |
| Up to 4200mm | 300mm |
Please note: Although 90% of windows have
sills, if your windows don't, then don't despair! We have a solution for
that.
We can supply a false sill which all rollershutters needs for the curtain
to fully close down on.
The sill is aluminium and would be the same colour as the headbox and guides
and can come in 3 sizes:
24mm x 22mm $6.00 Lm.
24mm x 46mm $8.50 Lm.
24mm x 77mm $11.00 Lm.
To order a sill send an email and request a sill immediately after you place your order
I will then send you a PayPal request for payment.
Protruding door and window handel's
If your door or window handel is protruding out past the exterior wall, it will interfere with the operation of the shutter. This can be easily overcome, we can supply an "aluminium angle" that would be the same colour as the head box and guides, and they come in 3 sizes - 24mm x 22mm, or 24mm x 46mm, or 24mm x 77mm.
This angle with it's 24mm side is fixed to the wall, allowing it then to protrude out from the wall 22mm or 46mm or 77mm. The guides that support the Roller Shutter are 76mm wide x 28mm thick, so allowing for the thickness of the guide 28mm, the 22mm x 24mm angle would give a flush fit, the 46mm angle would give you a space of 18mm, and the 77mm angle would give you a space of 49mm. If you have a sill you will need 3 angles (one each side and one for the top), if there is no sill you will need 4 angles. Fit these angles to the wall with the angles facing inward so they are hidden behind the Rollershutter, then fasten the Rollershutter to the angles.
