    Seems a good product and blends in very well with our decor.
    I had internet quote which was straightforward with good tips and advise on the measuring. Felt confident when I sent it that it would be ok.
    I sent for quote as diy and fitted by extra glaze and my only thought was that their quote for fitting sounded quite high.

    Thank you Lee for the positive feedback. It is true that the labour cost of our Fitted by Us service can be quite high. This is dependent largely on the distance from our nearest fitter and whether the work can be done in one or a series of days that might include overnight stays, etc. Just like we...

    What a difference!! No more cold blasts when you pass the windows.
    Very nice chap from Extraglaze fitted the product to my very draughty sash windows. The price did come up a little more than the on line pricing tool but nothing is perfect. Very clean and tidy workmanship and completed within the agreen time scale.
    Product : Very discrete panels...

    Cannot recommend highly enough - superb service and standard
    First class - I made a mistake on my measuring and Nic and his team could not have been more accommodating. Glazing is now in place and looks superb. The white border on both glazing and inner magnet (ensuring it still looks discreet in summer when the glazing is removed) is very good...

Sound proofing your windows

 


Extraglaze secondary glazing offers many proven benefits:
  • sound proofing
  • thermal insulation
  • draught proofing
  • eliminates condensation.

Extraglaze, a company based in Shrewsbury, does all this without changing the appearance of your windows, whether inside or out.

It adds sound proofing to your window by creating a sealed cavity on the inside of your window. And you can still open your windows. Whereas an Extraglaze installation remains nearly invisible, other types of secondary glazing will change the look of your windows.

You must be very cautious if someone suggests modern replacement glazing is a good sound proofing solution. Is Extraglaze better? Quite simply, yes. In fact we have proven this to be the case, scientifically.

If your windows are old then they are probably draughty. Sound is exceptionally good at getting through channels, around rebates and between unsealed surfaces. Extraglaze seals up all those draughty openings, without making any alterations to the working of your windows.
