Emergency safety information and telephone warning system

Use the links below to help you understand what to do when our site alarm goes off (5 minute oscillating blast), or to register for our telephone warn and inform system. This system allows us (or other companies in the Barry Industrial Complex) to call registered people with a recorded message in the event of a major emergency. We test our alarm at 15:00 each Monday afternoon.

Site information

At Barry we manufacture silicon-based products and intermediates for use by customers around the world. We start with pieces of elemental silicon which are chemically reacted and changed to make silicon-based fluids, gums, rubbers and specialty polymers. These are then sold to our customers and used as ingredients to their products. Silicon-based materials are found in many everyday products from personal care products (shampoos, make up, deodorants) to car airbag coatings and sealants and can be made to protect, lubricate, strengthen, adhere or conduct. We also supply many other Dow Corning sites with basic silicone polymers for their downstream processes.

The Barry site brochure (PDF size  = 343 KB) provides information on the site's activities in the community and explains our commitment to health, safety and the environment. Our manufacturing process is also described in the brochure. Printed copies are available from the site on request.


The 160-acre site is situated to the eastern part of Barry, South Wales, UK in the county of the Vale of Glamorgan. With sea docks right next to the site and excellent rail and road links to other parts of the UK and Europe, Barry makes an ideal location for manufacturing. In fact, many of our finished products are shipped from Barry docks direct to our customers in Asia, Australia and Europe.

Historical Roots

The link with Barry and Dow Corning dates back to 1952 when manufacturing of silicon-based materials first began.  Under the joint-venture name of Midland Silicones, Dow Corning and Albright & Wilson started making silicon-based products. Dow Corning took complete ownership of the site in 1971. The site has seen significant investment through the years to create a highly technical and modern silicones manufacturing plant. The Barry site is the largest plant operated by Dow Corning in Europe.

Serving customers globally

Through the expertise and dedication of our employees and the quality products we supply, our customers based around the world can produce: the air bags that protect the lives of car passengers, fabric treatments that make our clothes feel soft, coatings that help preserve our heritage, make up that applies smoothly and is non-greasy, shampoos to make our hair shiny, polishes to protect cars and furniture, sealants that allow glass buildings to stay together, as well as a huge number of other applications.

Dow Corning maintains a corporate ISO9001 registration. Tools to meet customer requirements include: internal and external audits, a Quality Notification system and Six Sigma methodology.

Barry site nature center

The site is fortunate to have an area of natural wetland, our nature center, in which wildlife can flourish. Set adjacent to the manufacturing site, the area serves as a large fishing amenity with two large ponds. Reed beds and meadowland complement the ponds and serve as extended habitats for many different species of plants, animals and insects.

Overlooking the ponds is our education center in which we host school groups interested in learning about eco-systems, wildlife and sustainability. The building is made as sustainable as possible with materials of construction being sourced  from managed forests or made incorporating eco-friendly principles. We incorporate several eco-friendly technologies: ground source heating to heat the building, solar photovoltaics to provide power while rainwater harvesting provides water for the restrooms.
