Specialists in fibreglass doors

Thermod manufactures fibreglass doors for environments with high demands on design, durability, hygiene and fire safety. With a market-leading product line, we offer customized door solutions for cold environments, public environments and medical environments. We are headquartered in Arvika, Sweden but also have production and sales facilities in Poland.


Thermod began manufacturing doors in Arvika, Sweden in the early 1970s. Our core product was then, and remains to this day, doors made of fibreglass-reinforced polyester.

In 1990, production moved to new, modern facilities in Poznan, Poland. This factory remains our production base.

In August 2012, Thermod was bought by listed company Lagercrantz and is now part of its Niche Products division.

Through continuous development – with a clear focus on sustainability, functionality and simplicity – we have been at the forefront of innovative door solutions in demanding environments and are now market leaders in our segments.
