How To Measure for Perfect Fit
Perfect fit are designed for use, solely on UPVC double glazed windows and doors. They will not be suitable for windows with wood or metal frames.
What you will need
- Pen and paper
- Tape measure
- Straight edge or ruler
- Butter knife
Perfect Fit Blinds – Preparation and measuring
A perfect fit blind is a blind (pleated, venetian, roller or wood), within an aluminium frame which then installs within each glass panel of a UPVC double glazed window.
Before measuring there are some things you will need to check to ensure that your UPVC window is compatible with this blind type;
- The blind frame will overlap by 2.5cm on all four sides of the window panel. This overlap will be measured from the visible glass, outward, over the window frame beading. You will therefore need to ensure that there are no window handles, vents or other protrusions, are sat within this area.
- Ensure that the brackets can be inserted under the rubber window seals. Use a butter knife, as illustrated above to check this. A minimum insertion of 2cm is required.
Once you have done the checks above you are ready to measure for your perfect fit blind(s).
- Unlike most other blind types, when measuring for perfect fit blinds for your UPVC doors or windows, you will need to supply us with the visible glass dimensions, i.e. the precise width and height dimensions of the pane of glass, where the blind will be installed.
- Each pane of glass on your window will need its own blind.
- Measure width first then height.
- Measure in centimetres to the nearest 0.1cm (1 millimetre).
- If you have black rubber seals which protrude over your glass, measure the “visible glass dimensions”, from black rubber to black rubber for the width and for the height. These are the dimensions to use when placing your order.
- If the black rubber seals do not protrude out over the glass, we suggest that you deduct 2mm from the width only of the visible glass dimensions to ensure that the brackets and frame will sit comfortably within this area. (For example if the width is 100cm order your width as 99.8cm. Do not deduct anything from the height). Use these dimensions to place your order.
- Write down your measurements as you go (width first, then height, clearly labelling them) and then have a break. Double check your dimensions later on to ensure you have not made any errors.
- Finally measure for your bracket size as outlined below and then place your order.
Perfect Fit Blinds – Measuring the Bracket Size
Measure the depth of the glass, in relation to each window frame. So the measurement from the front of the window beading back to the glass.
Place the straight edge/ruler diagonally across the corner of one of the windows, with the straight edge/ruler resting on the window frame/beading at each end. (This makes a triangle with the window frame making the bottom and side of the triangle and the straight edge/ruler making the long diagonal side of the triangle).
Measure downwards from straight edge/ruler to the glass. You are measuring the gap between the glass and the straight edge/ruler. Since the ruler/straight edge is sat on the window frame this gives you the depth from the frame to the glass.
This measurement will usually align perfectly to one of the available bracket sizes (18mm, 20mm, 22mm, 24mm or 30mm) and will determine the bracket size you will need to request.
If your measurement is slightly over or under the specified bracket size, you will need the next bracket size up. For example, if your glass depth is 19mm, you will need to request the 20mm bracket size.
If your glass depth is less than 18mm, you will not be able to use the perfect fit system and will need to look at an alternative blind type for your window.
What are window handle spacers for?
How do I measure for the window handle spacer?
Use a tape measure or ruler to measure from the back of your window handle to your window frame. If the back of your window handle sits less that 12 mm from your window frame then you will need a window handle spacer. We have two sizes of window handle spacers 2 mm and 6 mm. Order the sized spacer that will give you enough clearance to be able to turn your window handle once the perfect fit frame is installed eg if measurement from back of handle to window frame is 11 mm you will need a 2 mm spacer.
How do spacers install?
Unscrew your window handle, pop spacer where window handle sits. Screw your handle back on top of this spacer.
