Standard specification – Double glazed, air-filled units (4/16/4) with toughened inner and outer leaves conforming to current British Standards. As standard we use a K glass inner leaf which gives a U value 1.6. A whole range of specialist glass is available (softcoat which has U value of 1.4, antisun, argon filled etc).

Listed buildings and those in conservation areas may be exempt from building regulations for their glass specifications.


Pilkington T glass used achieves class A impact safety performance to BS6206:1981. Note: in the future references to BS6206 in BS6262-4 and relevant building regulations (e.g. part N in England and Wales) are likely to be superceded by BS EN 12600.

Glazing Cappings

As standard we supply white powder coated aluminium cappings with E.P.D.M seals which provide a maintenance free finish. If required, painted timber cappings (with E.P.D.M seals) can be supplied at no extra cost.

Opening Skylights (applicable to roof lanterns without glazed sidelights). Powder coated aluminium.

Note: Coloured paint finishes can also be provided at additional cost. We do have our own colour range but if a specific colour is required we can match your RAL colour or equivalent.
