We are an independent, family owned and run insulating glass unit manufacturing company and our team has been involved with glass for over twenty years.

We have invested significantly in the business to ensure that we are able to offer top notch products using only the finest materials and state of the art manufacturing technology. We truly are large enough to cope with almost any requirement yet we remain small enough to really care and we treat our customers as we ourselves would want to be treated.

Our products are delivered by our own drivers in our own fleet of delivery vehicles and we are very proud of our record of striving to deliver orders on time every time.

Quality is at the heart of everything we do at Premier DGU and our CMS Mark testifies to our compliance with the EN1279 part 1-2-6 harmonised European Standard. We are also members of the Glass and Glazing Federation, which upholds the highest standards of quality and service.

We provide materials from the world’s leading flat glass makers including Pilkington, Guardian AGC and Saint-Gobain, our range includes ultimate performance coated glasses, body tint base glasses, ultra clear low iron glasses and toughened and laminated safety glasses.

We feature the Super Spacer high performance warm edge spacer system that offers real in–use advantages over the more conventional box spacers that we can also offer. Our unit sealant of choice is hotmelt butyl which provides excellent performance combined with outstanding durability.

Our FOREL fully automated unit manufacturing line features a quality and shape scanner, a Super Spacer application robot, a flood fill gas press and a hotmelt butyl sealing robot and produces outstanding quality units, free from human error and to a high degree of consistency. We have recently added a BYSTRONIC fully automated unit line which has the same features as the FOREL line with added facilities to make triple glazed units.

We have also retained our manual IG unit line in order to offer a skilled, hand finished service to almost any glass requirement you may have including narrow cavity slim sightline ‘ heritage ‘ units.

The performance of glass and window and door systems has improved so dramatically in the last ten years and we have been at the forefront of insulating glass unit development. We work in partnership with the leading glass manufacturers Saint Gobain, Pilkington and Guardian to ensure that we are kept abreast of coating development and our IG units feature the world leading Super Spacer warm edge technology.

Super Spacer is more than 950 times less conductive than conventional aluminium spacers. As a result windows fitted with Super Spacer are up to 65% warmer at the edge. Condensation can be virtually eliminated and a reduction in noise of up to 2dB can help create a haven of calm. Most of the energy loss through a window occurs at the edge of the glass but using Super Spacer in insulating glass units can reduce heat energy losses by up to 94% from a typical home.

Let's work together.
