Re: Apart from cost, any downside in using toughened glass? 14May 20, 2009 8:07 pm Hi, have you thought about laminated glass ? The one pane which is more likely to be scratched anyway. It is also more soundproof and quite burglar resistant. I don't know about Australia but the over here the price for laminated glass is pretty much the same or sometimes even less than toughened glass. Change is what we need! Can we? YES WE CAN!!!!! Re: Apart from cost, any downside in using toughened glass? 15May 20, 2009 8:40 pm My windows are double glazed and quite large (2 m x 2.7 m in some cases), so the weight will be quite high. Laminated glass seems to come in thicker sheets and therefore the weight would go up. Also, the frame pocket varies from 16 mm for the sliding windows up to 24 mm for the fixed windows. If I went for laminated glass in the sliding windows the already too small air gap of 8 mm would be even smaller! So, maybe I've got my thinking wrong, but laminated glass seems like a step in the wrong direction.

Laminated glass has the advantage that cuts out 99% of the UV plus it has a better noise insulation value. There is also an special version of the lam that is manufactured for noise reduction purposes. In IGUs (Double Glazing) it is important to keep a 30% difference of thickness in the two glass panes to achieve best results in regard to noise reduction. In regard to stepping up the forced entry barrier laminated glass is definitely preferable. The weight shouldn't be an issue after installation at least when you have the right window and door hardware components. Weight is he worst argument when compromising on comfort or security. The air gap of 8mm or less with laminated would drive my decision here. As we are talking changing of glass there is probably not much you can do about it if you don’t decide to go with the system that allows for this alterations while maintaining an air gap +10mm.

Best regards Kris Thanks Kris, UV reduction: not important Noise insulation: not imporant Forced entry: This would be nice, but only for a small number of windows at the front at ground level Weight: Important, as I imagine 150 kg can be handles by four people, but once you get much above this I'll need a crane $$$$$ Air gap: Very important. Like you, I'm not happy with 8 mm, but going any smaller would be a disaster. Maybe I'll get argon put into the 8 mm gap windows (the sliding windows), but then only if it can be done for no more than about $50 per window.

Please keep in mind it's still glass after all. Not knowing you system the security risk could also be the locking and not the glass. If you should take laminated the UV reduction is a nice extra that safe your furniture from fading and helps to reduce the UV impact on the eyes. Argon gas can improve a unit performance by around 10% depending on the glazing type. I have seen researches that suggest that argon works better with 14mm air gap instead of 12mm air gap. Not quite sure what that means for a unit of 8mm or less. Weight: Is hard to say, depending on accessibility of your building it is possible to work with higher weights. We regularly end up supplying unit of 200kg plus that are handled without a crane. Double Glazing causes more weight but it will pay of in living comfort, so it's worth the effort.

If by this you mean the extra for Argon, it should be less than $10/m2.

My sliding windows are just under 4 m2 each, so I'll be able to upgrade each of the 9 sliding windows for less than $50 each. This should bring the 8 mm gap for the sliding windows up to the same thermal performance as the other windowes which have a 12 mm air gap (from the graph you provided Ed). It's all coming together Thanks for your help Ed, Kris, windowexpert, et al.
