Our Story

We’ve been designing and manufacturing high performance sealing systems for 40 years. Our intumescent seals are a vital part of a fire door assembly, helping to defend buildings against the spread of fire. Our smoke seals restrict smoke movement around a building - giving people time to escape, and reducing property damage.

We aim to be the best in the world in our sector.  We’ve built a strong reputation for design innovation; and for producing the highest quality sealing systems embracing acoustic, smoke, fire and thermal containment; as well as accessibility.  Our dedicated R&D and testing facilities rigorously put our sealing systems through their paces — enabling us to enhance product form and function. 

Respected throughout the industry for our technical expertise, we play an active role in helping to shape standards and best practice. We believe in providing excellent levels of customer service; and are at our best working in partnership with you.

We’re proud of our past, but even more excited for our future!
