We export 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 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 Perma Led, 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 and Thermoflex warm edge spacers. 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.
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 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.
