Recess or shutter size

Easy reading

Recess

If you have measured the width and height of your window opening please select ‘Recess’ from the drop down menu on the order form.  10mm will be deducted from your measurements to create a clearance gap between the shutter frame and the wall to allow the shutters to be fitted.  This clearance gap is called the ‘shadow gap’.

Shutter size (for bays, shapes or outside recess fittings)

If you have made your own allowance and your measurements are the exact shutter frame size then select ‘Shutter size’ no deductions will be made.

The ‘shadow gap’ is the secret to fitting shutters, it allows the shutter frame to fit easily into the window recess because of the clearance gap between the wall/architrave and the shutter frame.

This allows you to adjust the shutters left/right and up/down to obtain the perfect fit.

This is a very important part of ordering the shutters so make sure you understand how the shutters will fit allowing for the clearance.

Technical stuff

Recess

The 5mm clearance between the wall and the shutter frame know as the ‘shadow gap’ allows the shutter frame to be adjusted up and down and left and right.  This is done by using plastic wedges between the wall and the shutter frame allowing the frame to be screwed into position.This makes fitting very easy, as many windows are out of square. 

The shadow gap guides the eye towards the shutters, so the actual gap is not as obvious.

This method is often used when fitting built-in furniture and does not require covering or filling.

Shutter size

Make sure you have allowed enough clearance when ordering the exact shutter frame size.  The shutters are not designed to be cut or planned to size.

Sams tips

If your window is out of square ensure you take the smallest width and height measurement. 

I have very rarely come across a square window.   It is only when trying to fit something square in the window that you realise how far out the sides and window sill really were. 

So do not worry wonky walls and plaster work is very normal.  This becomes less obvious if you allow for a larger shadow gap.
