Tools needed for double glazing
Working with glass is non trivial, but it is made a lot easier by having the right tools. This is a list of the equipment that we find is most useful, especially when working with larger windows.
These make the job of lifting windows into position safer and easier. You can buy the orange one on EBAY for around $15. However, I would recommend the proper glazier suction cup (black). It costs a lot more ($130) but has a much stronger lift. More importantly, you pump up the suction, knowing that if the red line is hidden (see insert on photo) it will lift 50 Kg. We offer to buy them back from clients when they are finished for $100. Note: A customer recently required a new doule glazed unit when his cheap suction cup failed. If you use the cheap ones, use two.
Quality gardening gloves are a good investment, especially when removing glass, or lifting heavy glass sections. It is worth paying a little extra and get the gloves that are strong and flexible. The cost is around $15 at your gardening store.
These are essential when trying to remove glass without breaking it. It is important to get one that is as thin as possible, but be careful you don't cut yourself on the edge of the knife. I grind the edge of the putty knife at 45 degrees then tape it to a plastic handle. It looks deadly but it works well!
This is essential to ensure that you can cut the beading at the correct angle so that it joins neatly. A better option is a drop saw with a fine blade, but it is expensive.
A good sharp chisel is extremely useful to remove wooden beading and to clean away the remnants of the silicone when removing old glass.
This is the easiest way to remove silicon from the frame. However tit costs $60 and I have only found it at Total Tools. A chisel will also work OK.
This is only required if you need to widen or deepen the window frame. You need a light weight router and we found the Ryobi to be the best. It costs around $100. You will also need a wider router bit, costing $20.
This is the best material to use for beading to hold the window in place. It covers the edge nicely and is easy to cut and nail or screw into place. It is best to paint it before installing and then touch up afterwards.
6 MM capping
Where the window extends beyond the frame (normally only for wind out windows) the 30 mm wide, 6 mm thick round edged capping is most suitable. It is best to use Tasmanian oak rather than pine. It is best to paint it before installing and then touch it up afterwards.
The most commonly required seal is a 9mm wide, 1 mm thick rubber seal. This has adhesive on one side. Sometimes the 2 mm thick tape is better if the frames are not well shaped. This tape is not available in normal hardware stores.
These go under the glass unit to keep it clear of the wood and avoid it sitting in water. These are not available in normal hardware stores.
Methylated spirits and paper towel is the best way to clean silicon off windows. Make sure you do it within 5 hours of installing the windows. It will also remove excess black sealant from the glass.
