How To Install Blinds On A Double Window

Are you a DIY enthusiast? Then this is the job for you. Installing blinds on a double window is not that difficult. You just need to get hold of the right equipment.

If you have recently installed double-glazed windows, you will notice that your older blinds do not cover the whole frame. The reason for this is that double windows are sleek and fit more snugly on your windows. The older blinds now leave a big gap, which is not great for privacy. So, it is a good idea to get new blinds that fit the bill.
Insulation is the primary factor that is driving the rising interest toward double glazing. With energy prices sky-rocketing, double-glazed windows are a necessity nowadays. Also, they are a much more environment-friendly alternative to single glazed windows. Even though they cost slightly higher than single-glazed windows, the benefit of double-glazed windows easily outweighs the additional costs.

Double-glazed windows are two glass frames with a layer of air trapped within. The two glass frames, along with the air trapped in between, provides enhanced thermal resistance against freezing winter temperatures. It also minimizes noise transfer.

Most double-glazed windows are made out of uPVC or PVC frames. They are more durable and non-conductive than aluminum or wooden frames. So first, let’s take a look at how you can fit blinds on uPVC double windows.

Since all blinds and shades are different, we always recommend checking with your blind manufacturer or retailer first before making any modifications to your blinds. As well, if you are uncomfortable on your own, look for the help of a professional.

UPVC Double Windows

If drilling is not your thing, there is good news for you. You can order clip ‘n’ fit systems along with your blind. These are ready-made to fit in snugly inside the rubber seal of the UPVC frame. The secure fit and the tension created by suction, keep it firmly lodged in place. Just fix them and get your blind up and running in no time. They also come with heat-reflecting coating, to prevent thermal transfer.

To fit a more traditional bracket, you’ll need the following tools:
• Drill with a 3mm drill bit
• A tape measure
• A Spirit level device
• A pencil
• Screws and brackets included with the blind

Step 1: Check your window for any obstructions. Make sure window handles or levers are out of the way. If they are causing obstruction, consider moving your blind further back, so that they can hang flat.

Step 2: Select a spot on the uPVC frame for your first bracket to go in. Place your bracket along with the spot.

Step 3: Use a pencil or pen to mark the spots where the two screws will go in to fit the bracket.

Step 4: Finally, its drill-time. Use your drill to make holes over the pencil marks.

Step 5: Align the brackets over the marks and use the drill to put in the first screw and drill till it is almost tight.

Step 6:Now move the bracket around so that the second hole is visible through the relevant hole in the bracket. You can now fix the second screw in and make sure both the screws are tight.

Step 7:You’ll follow pretty much the same process to fix the second bracket. The main challenge here is to make sure that the second bracket is perfectly aligned to the first one.

Step 8: This is by far the trickiest bit. Put the Spirit Level on top of the first bracket you have just fixed. Position the second bracket under this level on the other side, and then keep adjusting until the second bracket is at the same level as the first one. If you get this wrong, you will end up with a lop-sided blind.

Step 9: Follow step 2-6 to fix the second bracket.

Step 10: Clip the headrail into the brackets along with the blind.

Step 11: Move the blind up and down a couple of times to make sure it’s moving smoothly.

Top Tip: Always use screws that are meant for the holes. Trying to drill in a bigger screw will crack the frame.

Fixing Blinds into Aluminium Frames

If you have aluminum or wooden frames for your double windows, the task would require a separate technique.
As metal frames are harder, you will need self-tapping screws for this. Self-tapping screws drill their own holes. The screw threads also seal the hole as they go in. In this case, the self-tapping screws will drill into the metal.

To make marks, you’ll follow pretty much the same method described above. However, the trick here lies in the drilling. For self-tapping screws, you need to drill a hole to the same diameter as the shaft of the screw, not the external screw diameter. The idea is that if you drill a small hole in the aluminum frame, the self-tapping screw will cut its own thread and fix the bracket firmly into the metal.

Also, take care that you don’t drill too close to the glass frame, which extends a bit into the aluminum frame.

Fixing Blinds into Wooden Frames

If you are fixing blinds into a wooden frame, no need to drill. Simply, use a screwdriver to get the screws in. The task will be easier if you use a bradawl to make the holes first.

However, it is advisable to make the hole away from the glass as the glass frame may extend a little bit into the frames.

When you are fixing brackets into wooden frames, do keep in mind that these frames are usually very thin. They will hold up your blinds as long as they are not super heavy. So, think carefully before fixing the brackets on a wooden frame. Perhaps, fixing them on the wall would be a better option, or go for really light-weight blinds.

Safety Tip: Dangling cords pose a choking hazard for children and pets. So, it is useful to fit in a hook by the side to strap the cords, to keep them out of reach of inquisitive hands.
Just take your time, and proceed with care. It may be a lengthy job, but the result will surely make you proud. All the best!
