Quality Control

Our aim to be ‘visionaries in glass’ and we are here to make an impact in the markets we serve. We have been manufacturing specialist products here in the UK for over 75 years and have built an extensive client base across the world.

Our success has been built upon providing solutions to customers’ complex requirements and building confidence that our products will perform, endure and exceed expectations. With a wide range of production capabilities and an experienced, skilled workforce we thrive on innovation and technology in both specialist glass and integrated solar markets.

Quality is embedded in all we do and we take pride in the products which leave our factory gates each morning. Above everything we want to make the Romag experience both effortless yet exciting so our clients achieve the perfect solution for their project.

We are based in Consett, Co Durham and we have an UK and international sales team. If you have a project you'd like to discuss, we'd love to hear from you.  You can contact the team on 01207 500000 or email us at

Design Service

Dellner Romag offer a comprehensive design and advisory service, supported by our in-house Technical Team, which begins at the customer enquiry stage all the way through to project delivery and after sales support.

Every product receives a full quality inspection before it leaves our factory for added piece of mind. We also offer bespoke packaging requirements (upon request) and deliver the majority of our products using our own dedicated fleet of vehicles.


Here at Dellner Romag we are committed to quality. For years, the quality of our products have set us aside from our competition and kept customers coming back for more.

Underpinning our ISO9001 certification is a fully integrated quality management system with full traceability functionality.

At each stage of our manufacturing process we conduct quality checks which ensure the final product is manufactured precisely to our customer’s requirements.

Such is our attention to detail that we even transport our own glass to customers for that additional assurance that the products reach their final destination in pristine condition, ready for installation. We marry our quality products with a quality service.

Our dedicated Customer Services team are on hand to guide you through your requirements and are backed by a skilled technical team who can advise on more complex requirements.

With over 75 years’ experience we have the expertise to find solutions to even the most complex of projects.


It’s clear that innovation is embraced here at Dellner Romag and is one of our core values. We understand the need to keep pace with changes in technology, advances in materials and step-changes in manufacturing capabilities.

We also understand that innovation often comes from working with our clients and partners and we take inspiration from those challenges which require new ways of thinking and new ways of working. So if you are looking for something new and can’t find a solution to your problem, why not give us a call and we can innovate together?


Dellner Romag's approach to sustainability is to look at balancing the different, and often competing needs of a manufacturing plant, against an awareness of the environmental, social and economic impacts we may have as a business. We are conscious about living within our environmental limits and understand that this also means considering the diverse needs of people in our existing and future communities. We can only do this by making better decisions and finding better ways of doing things, both for the future and the present. We are working hard to make Romag a ‘Planet Smart’ company and all areas of our business are challenged to generate continuous environmental improvements.


Trusted worldwide by leading organisations to deliver high quality products for complex projects we offer a range of bespoke products designed to meet our customers specific requirements.

In fact, it’s probably fair to say, the majority of the work we do is bespoke, but that doesn't always mean in small quantities.  We have produced 13,514 train windows for 886 carriages for 122 trains for the East Coast Mainline and Great Western services for Hitachi Rail Europe as well as many long term projects such as Crossrail.

Dellner Romag support a wide range of industry sectors and markets and many of our products are devised for high integrity, safety critical environments such as the oil and gas sector, military vehicles, high security buildings and museum and retail showcases. As we are in control of the end-to-end manufacturing process we have the capabilities to complete the most complex of projects making us well placed to turn your concepts into reality.

As a solutions provider, Dellner Romag has developed a customer base which stretches across the globe.

Our dedicated sales team welcome the opportunity to meet and discuss your specific requirements and can develop solutions bespoke to specific territories.

For example, we can offer additional testing (‘heat soaking’) for glass which must endure in high temperature environments.

As our products can often travel thousands of miles we can advise on appropriate packaging and transport arrangements to ensure products arrive safely and securely.

Dellner Romag is very experienced in all forms of overseas glazing design and offer bespoke solutions to complex glazing problems and have completed projects in over 30 countries across the globe, working regularly in the USA, Europe and the Far East.


Dellner Romag has been a manufacturer of specialist glass products since 1943 and all products are manufactured at our 80,000 sq.ft site in Consett, County Durham. 

We have an extensive range of glass and photovoltaic manufacturing equipment which provide extensive capabilities to manufacture the most complex of products.

These machines are operated by a multi-skilled workforce who understand how to process and handle glass and photovoltaic materials with care and precision.

For glass lamination we have a number of temperature and humidity controlled ‘clean rooms’ to ensure our glass laminates are of the highest quality every time.

Our manufacturing processes are fully certified to ISO9001 and we also hold OHSAS 18001:2007 certification, recognising the health and safety of our employees is of paramount importance.
