Double glazing

I had double glazing put in because I live behind noisy shops they put in 4mm toughened glass with 6.5mm hap hush glass should this reduce noise or was it a complete waste of money $2000 do you think I should take them to consumer protection thanks

Did it not lessen the noise?

No but they said they forgot to put gaskets around the weep holes in the window will this fix the outside noise problem once the gaskets are fitted they said there's about four small rubber gaskets

Get them to put in the gaskets and then decide.

Should this window of lessoned the noise

And does weep holes in double glazed windows have gaskets or are they just making excuses

So let me get this right - you have one pane of 4mm glass and another of 6.5mm glass. How big is the gap between? Double-glazing for noise is better when there is a bigger gap, but a smaller gaps for temperature insulation.

Well, any hole will let through sound.

They said there is only a 6.5mm gap now would this be worth $2000 in your opinion

It's toughness glass 4mm thick both sides with an 8 mm gap between the double glazing

So what was the reference to "with 6.5mm hap hush glass" in the original post?

Have a read of this.

I meant 6.5 mm hush glass with 4 mm toughened glass they said they fitted acoustics to it and they said the problem of the noise coming in thru the weep holes which they are fixing Friday 8 mm gap between double glazing

If you have it in writing that this would reduce your noise problem, it is their problem and you should expect a result.

But it is quite likely that noise was coming into your home from other places too, like walls, the ceiling and gaps between the window and house frame.

The thickness of the glass makes the biggest difference. The gap is almost irrelevant (yes, I know what they say). Similarly, laminated glass makes a small difference only.

Double glazing can make reduce some noise,but it is hard for it to reduce too much noise

sophie123 that would depend on the specs upon order placement, I had the same issue when ordering mine, I wanted a decent Rw rating to reduce as much noise as possible (I'm a light sleeper) so went through all the variable glass widths and gas space widths.
My only problem now is to prove the Rw reduction which was claimed and paid for.

Our windows are all laboratory tested... our standard double glazed window achieves Rw 35 and this can be upgraded to Rw 39.

These have been placed in projects with acoustic engineers reports which specify the likes of 12.38mm & 10.38mm glass, and have been measured in situ by the engineers and achieve the test results.

Glass is part of the solution, well designed, well-sealed windows are the other part. Without a test certificate, you really don't know what the result will be.

BTW our standard aluminium window is also the most energy efficient aluminium window in Australia... and carries a wind rating of N4 for an awning window, 2400 x 2400...

My guess is we will be 30% cheaper than any equivalent window.

hey mate, do you have any suppliers in sydney that you could recommend for double glazing?

Hi
Sorry I don't recommend in Sydney, I am not up to date with the Sydney market.

Thanks
