I am often asked if you can fit house shutters to UPVC windows, as there appears to be a concern that you can’t screw into the plastic window frame or that they would need to be fixed in some other way. However, the fact that the windows are UPVC is not an issue, as you could screw into this if you choose to, however, it’s not necessary.
Most UPVC windows have handles that protrude into the window recess, so this is the reason that it becomes necessary to fit the interior house shutters away from the window frame rather than the material the window frame is made from being the issue. With protruding handles, as you will see in one of my shortly forthcoming blogs on this subject, the louver blades being adjusted is actually the issue rather than the UPVC.
With most UPVC windows the best way to fit is to fix the shutter frame to battens that you fit inside the window recess. These form a sub-frame around the window, but most importantly move the actual shutter doors away from the window so that you can adjust the louvers without them hitting your window handles.
Some customers are concerned that attaching anything to their UPVC windows may invalidate guarantees, and I usually advise against fitting the house shutters to them for exactly this reason although it is possible. While different glazing companies cover different things it can be best to proceed with caution.
Some UPVC windows also have a plastic trim, which can either be removed when fitting or left in place and the battens fitted in front of it if you prefer.
The simple answer to this question is that fitting house shutters to UPVC windows is not an issue, and is simple to do whether we do it for you or you choose to do it yourself.
