Its not that simple, with Double Glazing you need to get it cut professionally otherwise you will get a build-up of condensation inside the glass divider. DO NOT DO THIS AT HOME
So true bro….. Hate when customers say “well I seen it done on RU-vid”. I tell them sorry ring someone else that does them, I don’t sorry lol and away I go onto the next job.
Wow, you made that look easy. I need to install a cat flap in a double glazed window. I've been quoted £500 ($625) by local people. I think I'll have a go myself. I'll see if I can get hold of some old sealed units to practice on first. What do I use to seal the unit once I have cut the holes out? Can not be metal as the cat flap has an RFID reader built in. Thanks
Couple of things. Toughened glass is unable to be cut!, by law low level glass, in door, next to door must be toughened saftey glass,... The hole is great and using bohle glass circle cutters are great for me need to done prior to avoid shells etc. Plus the hole will need to be sealed plus spacer bar or flex super spacer to give support on vent and of course keep water n rain out of insulation.. Orded double glazed unit with vent approx 240 mm in dia 80 mm upstand. That's your best bet. If you change the unit over yourself it's fairly easy job.. Good luck mate
you will be paying those people to do it any way, glass doors are tempered thats why it cost so much because they have to order the glass tempered with hole precut
@@Sythorize actually i've been trying to write a book where when we need to open the latch of the window... you need to cut a similar circular hole and pull it out... but yes the ball stick he used did shatter my hopes... so I just wanted to know if it's possible to pull it out without making noise... thanks
@@Kickbasser Yes, it's exactly the ball end of a glass cutter. The one he uses is admittedly the largest I've seen by far! I'd surmise a bit overkill though, for anyone below contractor-grade... X)
