Double Roller Blind - Inside Mount

Ensure you have at least 100 mm depth inside your window recess to ensure a flush inside mount. 

In this video, Michael uses a Top Front Double Bracket in a Combination roll to show you how to measure your windows for an inside mounted Double Roller Blind.

Measure the hard width at the top of your window inside the window recess.

*It is important that you take your width measurement from the top of the window as this is where your brackets will be fitted.

Next measure the hard drop from the inside top of your window to the inside bottom of your window.

Top Front Double Bracket

iseekblinds recommends that inside mounted roller blinds use the Top Front Double Bracket.  This bracket allows for 2 roll direction options.  

The top front double bracket will keep your fabrics close together, with the front rolled feature of the top blind neatly completing the look.

  • Front Rolled -  Both the top and rear blind are front rolled.  
  • Combination - The top blind is front rolled and the rear blind is back rolled.  

Handy Hint:  For bedrooms, iseekblinds recommends you use single roller blinds.  Inside mount your sunscreen blind and outside mount your block out blind.  This will provide you maximum privacy and room darkening.  Finish off your look with a stunning Pelmet 95!

Double Roller Blind - Outside Mount

The blind is attached on the outside to the architraves.

In this video, Michael demonstrates the simple process required to Measure your window for an Outside Mount Double Roller Blind, using the Top Back double bracket in a back rolled combination.

*Please note: iseekblinds will not make any deductions for Outside Mounted Blinds

Measure the width from the outside edge of the architrave to the outside edge of the architrave at the top of the window frame.

Next measure the hard drop from the top outside edge of the architrave to the bottom outside edge of the architrave.  This measurement may be increased if you want your blind to drop past the bottom of your window frame or to the floor.

Top Back Double Bracket

iseekblinds recommends that outside mounted roller blinds use the Top Back Double Bracket.    

  • Back Rolled -  Both the top and rear blind are back rolled.  This will ensure the fabric sits as close to the architrave as possible for greater light control and insulation.

Handy Hint: 

  • For bedrooms, iseekblinds recommends you use single roller blinds.  Inside mount your sunscreen blind and outside mount your block out blind.  This will provide you maximum privacy and room darkening. Finish off your look with a stunning Pelmet 95!

Blind Position

The rear blind is generally the sunscreen or light filtering blind, whereas the front blind is generally the  blockout or black out blind.  This means that the sunscreen or light filtering blind is closest to the glass providing protection against UV and glare, whilst the blockout blind can be moved up and down in the front position easily providing privacy and light control.

Michael's Tips

  • Always measure in millimetres (mm)
  • Always use a steel tape measure for accuracy - make sure the tape measure is straight and tight when you take your measurements.
  • Remember you can be 1 mm short, but you can't be 1 mm too long.
  • Measure all windows, even those that appear to be the same width and height
  • Add your room name to each of your blinds as you order them.
  • Do not take any deductions (iseekblinds will do this for you)
  • Measure at the top of the window frame where the blind is to be installed.  This is where your brackets will be placed.
  • The measurements provided by you will be taken as the outside edge of the roller blind bracket to the outside edge of the roller blind bracket - not the fabric width. 
  • In your open living areas, always try to fit your blinds inside the window frame.  You will require a window recess depth of at least 100 mm.
  • In bedrooms, iseekblinds recommends you use 2 single roller blinds.  Inside mount your sunscreen blind and outside mount your block out blind.  This will provide you maximum privacy and room darkening.
  • All blinds over 1800 mm wide should be ordered with a spring assist.  This will ensure your blinds glide smoothly up and down with minimal effort and will limit wear & tear on the components.
  • If you live near the coast, order your blinds with stainless steel chains.
