Saving lives and preserving property. Lorient designs and manufactures market-leading, high-performance door sealing systems. 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. Our seals still work hard every day to enhance a building’s performance, our acoustic door seals help to contain sound within a room, or prevent it entering. Many of our door seals also improve the building’s energy efficiency by keeping in heat. We also design our seals so the door can be used with minimal effort, helping those with reduced mobility. Integrated systems We offer a suite of products for fire resistant glazing, and also door hardware protection. Our intumescent grilles and fire dampers protect ductwork and walls, as well as doors. Taking this ‘system’ approach means we can recommend the most efficient, cost-effective combinations for every situation. Our technical strength With over 40 years, there’s not much we don’t know about door sealing. Respected throughout the industry for our technical depth, we share our knowledge openly with our door manufacturer customers, and support their product development in our own research laboratory. Testing and certification Our library of test evidence is second to none. We have a host of CERTIFIRE certificates; and we still remain the only seal manufacturer with BBA accreditation (for our main range of fire and smoke seals). It’s not only our products which excel. We boast both BS EN ISO 9001:2015 and BS EN ISO 14001:2015 accreditation. In 2013, we launched our very own Lorient Testing & Technical Services division featuring a brand new state-of-the-art acoustic transmission suite. In addition to our UK & Europe head office, we have a number of operations around the world; in North America, Hong Kong, Australia, Singapore and Dubai.
