Sash Windows Locks - What are the best locks to secure your Sash Windows
Old rattly sash windows that let the draft in remind us all I guess of stormy wintery nights, cuddling up in bed, either feeling safe and secure, or the windows are making such a racket that you get irritated and can’t sleep. Either way there is a lot of sash windows in houses and even though uPVC try to compete, you can’t really get away front the fact that wooden sash windows add character to a house.
Well thats my view anyway :-)
We have all seen I guess, the films like Shurelock Holmes where you see the bread knife being used to slide the clamp between the sashes to push the clasp back, and in truth that is, how easy it is to open a sash window.
Baring in mind the insurance companies want all accessible windows locked. This would mean, we need to be securing all windows that are on the ground floor, also windows from low lying roofs where access to the window can be achieved with no aids, for instance, to be able to climb onto a wall and then onto a roof that could lead you to a window that can be opened.
In my view, probably the best sash window locks are the barrel type that you can see in the picture, they are so easy to fit it really is that simple that within a few mins, you have secured your windows.
The idea in fitting them is you drill a hole through the first sash’s centre rail and then into the outer sash, not to go all the way through, put some tape on the drill bit so you can gauge how far you are going into the sashes.
Simply with a hammer and a soft wood block hammer the brass insert into the inside sash. screw in the bolt and thats about it. It is really that simple.
We can go a little further however, and make more use of these screw in bolts. If you move the bolt from the centre rail position to the outter part of the sashes (verticals), that slide by each other as you open the top or bottom sash We can now drill more than one hole in the outer sash, perhaps a few inches (6 inches probably be the max) from the closed secure hole. This now allows you to lock the window slightly open for ventilation.
Depending on the size of the sash we would always recommend two bolts to be fitted, obviously if the window is narrow, perhaps one would be ok, but on a typical front window to a house two bolts would be the preferred choice.
There are variations to the simple bolts that we have discussed today. Banham, make a nice quality product, the idea with these is they stop one sash from passing each other as you try to open them. Also you can buy extra inserts that again will allow you to open the window for ventilation.
The keys for all these types of locks are manufacture related, and will fit the range that the manufacture has to offer, so if your buying a house with sash windows and you have these type of locks already fitted, we can get you keys for them and I would suggest a simple phone call or email a photo over to us, we will then be able to give you advice as to what key will work with your lock.
I hope you have found this simple article helpful when choosing a lock to secure your sash windows, but as I have already mentioned, give us a call we would love to help you make the right choice for your window.
