Our Products

With over 2,500 insulated glass (IG) components in our product portfolio, we are the one-stop-shop for IG sealed unit manufacturers.  We supply the largest volume of spacer bar to the UK market and export many of our products to customers in over 40 countries on 6 continents.  We now manufacture over 50% of the products we supply including our own Thermobar and Thermoflex Warm Edge Spacers and the multitude of bespoke fittings to complement these ranges in manufacturing highest quality double, triple and even quadruple glazing units.

The latest addition to our wide range of products is the DecraLed decorative range which includes: Decra Led™ adhesive lead; Decra Glow™ range of films and Decra Bevels™ range of glass bevels and fused tiles.  To date, we have invested more in the manufacture of lead and decorative films than in the purchase of these products which includes a new state-of-the-art design studio with clean room and various additional processes to our lead manufacturing facilities including electroplating and powder coating our lead ranges.

Please navigate through our wide range of products below, which includes our own range of glass machinery designed and manufactured by our highly skilled in-house engineers.
