    Toughened Glass
    Toughened glass is more expensive than annealed and, due to the toughening process is renowned for problems of warping, scratches and imperfections. The delivery period for toughened is longer than for annealed units.

    SAFETY MARKINGS - Toughened units require safety makings. This can be a KITE MARK which is placed in a corner, not necessarily the same corner or a LINE LOGO which runs along the edge and is hardly visible. We can also provide a certificate.

    It is well worth only ordering toughened strictly when it is needed to reduce costs. (Please give us a call for guidance).
