Thermoseal Group Ltd

In 2017 we added the DecraLed decorative product range including: DECRA Led® adhesive lead strip and a wide range of DECRA Glow® Films; DECRA Bevels®; infused tiles and a multitude of decorative accessories to our own comprehensive range of decorative lead, film, bevels and fused tiles.

In recognition of our excellent products, quality and service, as well as our dedication to staff and customers, we were awarded one of the most prestigious awards for business in the UK; The Queen’s Award for Enterprise: International Trade 2017. This is just one of the accolades we have received – see our logos below.

Our export reach is world-wide, so whether you're a sealed unit manufacturer, a window fabricator or a double glazing installer in any location, we are also the one-stop-shop for IG components and machinery for all levels of glass sealed unit manufacture.

Thermoseal Group was founded in 1979 and quickly developed into an industry leader. Our original business was the sale of a limited amount of machinery from our small factory in Birmingham. Thermoseal Group now operates from four rapidly expanding branches in Birmingham, Wigan, Kent and Northern Ireland. We now stock and manufacture a wide range of insulated glass sealed unit components and machinery for sealed unit manufacturing.

Aside from our Kent-based lead plant where we produce our exclusive range of decorative DecraLed, most of our manufacturing processes have always taken place from our Birmingham factory. However, as the business has expanded, we now have a large manufacturing base in Wigan dedicated to the production of our own energy efficient products including – Thermobar warm edge spacer tube made with engineering plastic and Thermoflex warm edge spacers made from a flexible foam material.

We have also made significant investments in a new state-of-the-art decorative design studio to enable us to produce bespoke designs for our customers to incorporate into their own insulated glass products.

Alongside production on this site, we also have our own Innovation centre focussed on designing, developing and testing our range of products to meet the changing regulations. Research, development and manufacturing of future-proof products is now the focus of the Group.

In addition to this manufacturing base, we also have an expanding injection moulding division based in Birmingham where we are developing our own range of components compatible with key industry products including Thermobar and Thermoflex.

We are also active members of the Glass and Glazing Federation (GGF) and Bundesverband Flachglas (BF) and the IGMA working for the IG industry. Our warm edge spacers are also certified by the Passive House Institute (PHI). Thermobar is certified with a phA rating (phA+ with Hot Melt) and Thermoflex is certified phA+.

With innovation and a willingness to develop our industry as a priority, we offer a guaranteed quality of product and a reliable and timely delivery of goods, which in the UK are by our dedicated team of drivers.

We know that our customers have their own customers' needs to meet, so we make it our business to ensure that we provide a tailored supplier support system.

Bespoke glass machinery available includes: Gas filling machines, hot melt extruders, edge deletion machines, production lines and most other equipment for sealed unit manufacturing.
