BS EN 1279 Specialist Glass Products Limited  have obtained the certification for BS EN 1279 "Glass in building - insulating glass units." Previous to the introduction of this standard, curved glass units were not covered by standards relevant to sealed units.  Specialist Glass Products Limited are now compliant, giving our customers the reassurance that their units are manufactured to the latest European standard, as flat units with which they may be more familiar. All our sealed units carry a minimum warranty of 5 years.
