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.

We aim to get the Quick Quote proposal back to you within 24 hours. Please ensure you complete all field to enable us to respond as soon as possible.

DISCLAIMER: Please be aware that there is a +/- 1mm tolerance for all our double glazed glass units for glass size and sightlines.

    Gas (Required)
    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 markings. 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).

    U Value
    This indicates the thermal efficiency of units and there are options depending upon budget and efficiency.
