PVC window hinge length

[prs999]

Hi,

A bit of an odd one, we bought our house and the double glazing looks like it was done on the cheep.

Basically what we have is a unit with 4 x potentially opening windows.
the top 2 are all ok and opening, the bottom 2 were screwed shut.
They have never had a lock or hinges they have just screwed them inside the outer frame and stuck in the glass.

We have had the glass and opening bit of the window out and we have all of the measurements for locks and hinges but we are unsure of what hinge length to use?

They will probably need to be top hung due to the size and each of b the windows in 1 room are 700w x900h and the other are 110w x 900h.

any opinions would be much appreciated

thanks

Not done on the cheap, I have some like this. It's done so it looks more even from outside. If you can remove them, they can have hinges and locking mechanisms fitted, bit of work though!

Are these parts the same size as the opening ones? If so you can copy the hinge size from them?

They're called dummy sashes just like phatboy says, they have been specified like this so from the outside the frame thicknesses are equal and possibly to give the effect of an opener, effectively yes you could fit hinges to make it an opener but then you'll need a locking mechanism and handle and both will need the PVC routering out to take them,

Hi,

Thanks for the replys, interesting about the dummy windows. we already have all of the other dimensions, as suggested we had removed the other windows and measured these.

In relation to the hinge length I found this shop that states the window size for the hinge length in a table so question answered

incase it us useful to anyone else
