We understand that installing your own shutters can seem like a tall order. But with the help of our partners at California Shutters, you’ll be done in no time.

Our customers often ask us if shutters can be installed on UPVC windows and conservatories. Well, the answer is a resounding yes! But before you start drilling, let’s see what the experts have to say.

Fitting shutters to UPVC: What to look out for

Fitting interior shutters to UPVC windows is almost the same as if you were fitting them to wooden windows. The only difference is that when you’re screwing your shutter frame into the UPVC, you need to stop drilling when you feel the screw begin to bite. And that’s it!

Larger handles are more common on UPVC windows, so this should be factored in when measuring. You should ensure there’s enough space between the handles and where the shutter frame will sit. This gives the slats enough space to turn fully.

To find out how to choose the right slat size for your home, head over to the California Shutters blog.

What shutter frame should I choose for my UPVC window?

TThere are a couple of frame options for your UPVC windows.

Inside mount L frame

These frames come with pre-drilled fixing holes and attach within your window recess at the sides, top, and bottom. Therefore, choosing this frame option doesn’t involve drilling into your windows. Inside mount frames are the most popular option, as they provide a neat finish and are the easiest to measure for.

Outside mount Z frame

If your window doesn’t have a recess and is in line with the wall, like traditional sash windows, an L frame is likely the best option for you. It can be installed into the window or the surrounding wall.

Please note that many modern UPVC sash windows can tilt inwards. If this is the case, get in touch as you may require a different fitting.

Can I get shutter blinds for my UPVC conservatory?

Measuring and installing shutters for a UPVC conservatory will depend on the shape and size of your space.

Often, a conservatory is made up of a boxed shape, and in this case, the inside mount frame (as discussed above) would be the perfect fit. If your conservatory has window sections at an angle, fixing the shutter fame directly into the window will work best.

Remember, there’s no need to worry about drilling your plantation shutters into the UPVC. All you need to remember is to stop drilling when the screw bites. 

If your conservatory is particularly unusual, or you’re unsure of how to measure or install your interior shutters, feel free to email in a photo. The team at California Shutters will be more than happy to advise you on the best way to design and install the shutters for your space.
