Softcoat glass orders

Due to an inconsistent supply chain of our softcoat glass we are changing glass producers which may result in a slight difference in the tint of the glass. If you require glass to match a previous order please let us know at the time of enquiry and quote the previous job number.

    Gas
    Argon Gas - Will give a lower "U" value in a slim unit. But cost effective. OK for thicker units 20mm+
    Krypton Gas - Good "U" value but more expensive
    No Gas - Will give very poor "U" value. NOT RECOMMENDED

    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).
