By Louie Watts on 13th August in Home Inspiration As we all know, uPVC is used in many home improvement products nowadays as it’s durable, easy to clean and has a prolonged lifespan, but as with the majority of materials, it is susceptible to swelling and contracting with intense heat and cold. So how can we prevent uPVC expanding? How can you prevent your uPVC windows or doors from expanding in the heat? In extreme heat, you may have noticed your windows or doors becoming stiff or not opening or closing properly. This could be because the uPVC has swollen. at 40ºC your uPVC can expand by up to 2.4cm, which is quite a lot. Do not worry though, your windows and doors are not going to break, this is a perfectly natural occurrence. It will actually sort itself out – as when the Sun sets, your windows and doors will retract, returning to normal. In extreme circumstances you can cool down your uPVC by patting it down with a cold, damp cloth or alternatively spraying the outside with water.
This should help the uPVC shrink back to size and work freely once more.

If you believe you have particularly vulnerable uPVC windows, or perhaps are going away from the house for a time then the HomeSecure Sash Jammers are ideal for providing extra security.
These window locks are visible and act as a deterrent to any attack on your window. These window locks are easily fitted by two screws. With the window in use the arm of the window lock is moved out of the way and isolated until required. By drilling two small pilot holes holes, away from the glass line, into the opening window frame the window lock can be screwed securely into place using the screws provided. By inserting the closest size spacer into the underside of the arm the gap can be reduced to the frame. These locks can also be used on doors for extra door security and also for doors that open unless key locked - just swing the HomeSecure sash jammer arm across when you come into the house! *x3 Button Spacers (Small, Medium & Large) How many to use? 1 Sash Jammer - Small Window 2 Sash Jammers - Large Window / Single Door (Top & Bottom Fitting) 4 Sash Jammers - French/ Patio Doors (2 Top, 2 Bottom, on each door) *We recommend using Jack Nuts to gain a secure fit onto un-reinforced window frames*
