2. Brackets.
Ok, this next step needs some thought to achieve the best results – ‘how much depth will the PVC blind headrail take up, what depth of window reveal do I have to work with, what obstructions if any are present (handles, stays, latches or catches), and how deep do I want to blind set back, if at all, are all worthy questions to ask oneself. Setting the PVC blind about 10mm back from the architrave always looks pretty good. To achieve that, bearing in mind the fascia goes in front of the brackets, you may want to measure back about 15mm from the architrave to the front face of the bracket. Some shallower reveals may just mean you don’t set the PVC blind back at all. Hold the bracket in the desired position and mark it with a pencil. Mark where the 2 screws per bracket will go. You can put the screws up through the top of the bracket or through the side of the bracket; it doesn’t really matter.
Each end of a PVC blind needs an end bracket; there’s a left and a right and they’ll be marked accordingly (L & R). For PVC blinds 1.7m and over there will be intermediary bracket supplied with that specific blind. When marking these middle brackets; the back of an intermediary bracket should line up with the back of the end brackets.
This is where the measuring tape is pretty useful. Again, mark your holes for fitting the screws and securing the brackets.
TIP 1: Think about where you’re going to place intermediary brackets in relation to PVC blind ‘ladders’. That’s those dangly string bits holding the blind together. This can be done by lying the PVC blind down and measuring the best locations for any intermediary brackets.
3. Blinds.
Well done, the brackets are secure and it’s time to fit your new PVC blinds. The end brackets have a hinge gate front to them. Leave one secured closed and have one wide open. Slide one end of the PVC blind headrail into the closed end bracket, lift the headrail high enough so the headrail will sit on the intermediary bracket (if there is one) and then slide the other end of the headrail into the open end bracket. Once the PVC blind is in, secure that bracket gate and it's ready to lower and operate. Just before sitting back and admiring your handiwork, you still have to put the fascia on the blind. Hold the fascia up level, hold centrally and fix to the headrail with the fixings supplied on the fascia.
