Double Glazing Query

[James310]

Hi

Can anyone help me with a query?

Do to us living close to traffic we wanted some new windows fitted to help reduce the noise. So we got quoted for the below :

'Clear low emission and heat retaining Pilkington K laminated/toughened double glazed units 10mm low E safety glass with warm spacer with Argon gas and 6.4mm laminated safety glass'

Windows were fitted and after the fitters had left we noticed the glass was Saint Gobain and we measured the thickness with a glass measure and discovered it was 6mm and 6mm, not 6mm and 10mm.

The reply back was that it is Pilkington glass but the double glazing units are put together by Saint Gobain and supplied to the window manufacturer (no sign of the Pilkington brand anywhere) As regards the thickness he said the windows we have did not accept the 6mm and 10mm thickness and the 10mm was an error, what we have is 2 x skins of laminated glass to dampen any noise.

So couple of questions.

1- Can it be Pilkington glass but with the Saint Gobain brand?

2- With regard to the thickness then is it true, is 2 x 6mm as effective as what we wanted which was 6mm and 10mm.

Are we being strung along or does it all make sense?
