Replacing double glazed PVC french doors and windows, for improved noise exclusion?

    I believe considerations are

    • how well they're installed and sealed
    • triple glazing, which is what I would opt for, upgrading from double glazing
    • an acoustic barrier layer? Some door come acoustically rated, is there a standard for this in Ireland or UK suppliers?

    Several folks have mentioned they've experienced a notable improvement in noise exclusion after upgrading their windows and glass doors.

    Where would I go looking specifically to ensure I'm getting the most acoustically sealed doors/windows, and best installation for noise exclusion?

    Mention in another thread of fitters in NI being most cost friendly than in ROI?

    Frame weight and strength is one of the factors in terms of durability over time, but also soundproofing. Look at the alu-clad range and pay attention to locking/latching mechanisms as these are key to ensuing a good seal.

    I got sound reducing double glazed windows installed.

    They've got one layer of 4mm and one layer of 6mm glass. I think the air gap is reduced to fit into a standard frame size.

    Different thicknesses of glass let through different sound frequencies so having two different thicknesses blocks more of the noise.

    I've found they greatly reduce the traffic noise relative to the previous double glazed windows.

    They were purchased from one of the standard window suppliers and I think are a fairly standard option.

    You can have a layer of 6mm glass in triple glazed windows as well.

    As the lad above says you need different thickness panes to reduce sound transmissions and for the triple glazed to have much of an impact on energy retention it needs two soft coated panes. With 2 soft coated panes and 6mm pane your light transmission is about 55% which is pretty significant in Ireland for 8 months of the year.
