Lorient seals are available in a wide range of standard colours as well as attractive woodgrain and metallic finishes. If a specific finish or colour is required for your project, Lorient has the technical ability and resources to produce it, even in relatively small quantities.
The intumescent material used in Lorient seals is sodium silicate based. This type of material has been proven in many hundreds of tests world-wide. It exhibits outstanding reliability and durability and, when exposed to fire, it remains stable at temperatures in the region of 1,000°C.
Lorient offers a choice of fire seal only and combined fire and smoke seal profiles. For optimum acoustic, smoke and fire protection, the DS or Finesse™ seal is always recommended. Other profiles also available:
Offered in standard sizes of 10 x 4mm, 15 x 4mm, and 20 x 4mm. Other sizes are available.
All Lorient fire and smoke seals have been tested in accordance with BS 476 Pts 20/22 and Pt 31.1 on a complete range of fire door configurations; single leaf, double leaf, single acting, double acting, latched and unlatched. Smoke seals have also been tested for acoustic performance in accordance with BS EN ISO 140-3:1995.
Doors must have gaps between the leaves and the frame and between the bottom of the door and the floor. These gaps allow the door to operate; however, they also allow the passage of smoke and fire. A Lorient sealing system provides a working, effective and attractive solution.
Smoke travels further than the fire itself and also travels at a much higher speed. These characteristics are the main causes of casualties and property damage. Effective smoke seals provide protection all around the door, including the threshold. As well as providing a permanent barrier to the smoke, they will also provide useful thermal or acoustic insulation.
Lorient fire and smoke seals are British Board of Agrément and CERTIFIRE approved (CF330/CF136) for use on timber-based fire door assemblies.
