The JWS Glass art system has been systematically developed and improved over the last 26 years, and the quality of our products is technically proven under the ISO 9001:2000 accreditation. All our products are suitable for use in insulated glass units and have been tested to comply with European standard EN1279.
Lead has been used for centuries in the creation of traditional leaded lights due to its malleability and ease of use. Our adhesive lead profiles retain these properties and our narrower widths are ideal for creating stunning decorative designs whilst our wider widths are used mainly for designs with straight lines. Our Self adhesive profiles are made with 99.5% pure lead which is modified with a small amount of antimony to improve its weathering performance and surface polish.
A high performance, acrylic, pressure sensitive adhesive ensures a long life span in double glazed units. All JWS Glass art products are manufactured to ISO 9001:2 quality standards and have been tested in units complying with the European standard EN1279. Our coated lead products have been fully weather and age tested to the ASTM-G53-96 standards.
The materials we use to construct our glass art have been used throughout the world in various installations . . . from the heat of the Australian outback to the cold and damp of a Russian winter . . . with no reported failures anywhere, we are so confident in our products we give a 10 year guarantee and an estimated life expectancy of over 25 years on those elements.
