  1. David Lemington

    Decent product, best price i found, will use again, thanks D

  2. Carl Rufford

    I found the Royale 6mm Supreme Gold better over all, slightly denser and better dB sound properties, but still a good underlay overall. Don’t forget the barrier tape too cause i forgot to order mine and the fitter charged me extra for using his own.

  3. Jenna Woods

    all fine – will be ordering more next week after we’ve finished the bedrooms – Jenna x
