Double glazing beading has beaten me

    I am failing to remove the bottom broken window unit from a double glazing window. The youtube videos make it look dead easy. :mrgreen: I bash my Moon Knife as hard as I can and it only goes in about 5mm. Flexing the knife at that point does not persuade the beading to pop. What am I doing wrong? :(

    Thanks in advance.

    Have you tried the middle of one of the longer sections? I would expect them to flex more.

    I have only ever done it once. I used two thin japanese cat's claws. I was able to apply pressure at two points near each other. Not sure if it makes any difference, but I think I used them in the opposite direction to you.

    Silly question..... have you removed the wedge gasket on the inside yet? That's an externally beaded frame and from what I can see you need to pull out the black gasket on the inside of the house , sealed unit should then push back.in and beads pop off really easily

    Sending you virtual kisses! :LOL: That was the vital bit of knowledge I didn't have. Once the inside gasket was removed the outside beading popped off like a dream. I was able to remove the window unit and measure it for a replacement. Presumably when I get the replacement I pop the outside things on first and then fit the inside gasket? That looks like it could be a fiddle.

    Thank you ronniecabers! :)

    Yes , Replacement is reverse of removal, so glass in , beads in , go inside and push glass out and them liberally spray around the edges of the window with window cleaner , makes putting the gasket in much easier, if need you can use the handle on a hammer or something similar to push the gasket in

    Why isn't the glass toughened? Perhaps it is higher than 800mm from the floor.

    With regards to suppliers. I recently asked a firm in Barnes to price for 2 DGUs, approx 200m by 200m. They warned me that there was a minimum charge. They wanted £120 ex VAT. I went online and found similar prices, when you factor in the £60 delivery charge. In the end I asked a supplier in west London (West End Glass)- he charged £36 ex VAT.

    As you say , could well be above the 800mm from finished floor ...BUT being obscure there is high probability its a bathroom and then if the bathis below it , then you have to factor in that the inside of the bath is officially the finished floor level as far as regs are concerned , aslo there is the ' slip ' risk ( duty of care ) but it may well be its above the basin ....we just can't tell from this picture ...

    As goes your units @opps , thats a lot of money £ 120 + vat ... most companies run a minimum of 0.3m2, £ 60 delivery charge is high too for units that small in size too. With delivery and including VAT , i would think we would be charging about £70, still high compared to where you got them from but sealed unit prices do vary around the country

    The glass is 130cm from the floor. It's a downstairs toilet. There is a basin directly below the window. Does it need to be toughened?

    Having trouble finding an online place that will deliver, Google just shows me places that want to sell me the whole window, frame and all.

    At 1300mm from finished floor ( both inside and out? ) , no need to toughen it. Whereabouts are you based?

    Outside the window is 100cm from the ground.

    Maidenhead Berkshire. Window is just 56 x 31 cm so I was hoping to find somewhere that would post it to me.

    I believe that it only needs to be toughened if lower than 800mm.

    The logic is quite simple, if for example, someone slips and puts their arm through the window, a shard might cut through an artery. If toughened, it justs breaks in to tiny bits.

    AFAIK, virtually all glazing shops send the glass off to be toughened, adding a few days of delay. It will also add extra to the cost.
