Exceptional Acoustic Performance

The Lorient LAS7001 acoustic perimeter seal effectively blocks unwanted noise, delivering acoustic reductions of up to 33dB Rw. Acoustic door seals actively contribute to quieter indoor environments, significantly improving privacy and comfort within offices, meeting rooms, educational facilities, and healthcare settings. 

By forming an airtight seal around doors, this seal prevents noise intrusion and maintains acoustic integrity which is critical in busy buildings where confidentiality and productivity are a focus. Fit in conjunction with the Lorient LAS8004 or LAS8001 drop seal for a complete acoustic sealing solution.

Reliable Smoke Protection

Engineered to meet stringent fire and smoke safety standards, the Lorient LAS7001 perimeter seal offers essential protection for both 30-minute and 60-minute fire-rated doors. Its design ensures sealing against smoke leakage when the door is closed. This aids in preventing smoke migration in an emergency and maintaining visibility for safe evacuation. 

Thoroughly tested in line with BS 476-31.1 and EN 1634-3, it guarantees compliance with building regulations, supporting fire safety strategies across commercial, public sector, and residential developments. It is effective as a smoke seal up to 200°C. This is not an intumescent seal, so ensure you have effective fire seals installed, like the Lorient plain fire seal - available in 3 width options and various finishes.

Versatile Perimeter Sealing

Manufactured from aluminium, the LAS7001 features a durable carrier paired with a high-performance, flexible silicone gasket. This resilient design withstands frequent use offering lasting performance and minimal maintenance. Check regularly to make sure the seal is intact, securely fixed, and that the door latches with every use. 

The aluminium component is available in various finishes to match interior aesthetics and other elements of door hardware. Easy to install onto existing or new door assemblies, the LAS7001 can be cut to size directly on-site, ensuring quick and accurate fitting to the head and jamb.

Installing the LAS7001 perimeter seal is straightforward and practical. Surface-mounted to the stop of both timber and steel-based doors, this seal does not require specialist tools. The pre-slotted fixing holes make it suitable for rapid installation and adjustment once fitted. A decorative cover strip conceals fixings and makes for a neat finish. 

This seal can be fitted without removing the door. Remember to allow for mitred corner joints when measuring the length. If used in conjunction with a face-fixing threshold seal, install this perimeter seal to the door frame first. It is supplied with self-tapping wood screws. Metal door fixings are available on request.

Compliance with Building Regulations

Meeting the requirements of Approved Document E for acoustics, the LAS7001 ensures regulatory compliance for acoustic performance in residential and commercial applications. The seal has undergone rigorous third-party testing under BS EN ISO 10140-2, demonstrating proven acoustic performance in real-world conditions. 

This thorough testing reassures specifiers, contractors, and facility managers that installing the Lorient perimeter seal meets current regulatory requirements. Certifire Approved, this seal is certified as suitable for use on steel and timber-based door assemblies, delivering peace of mind no matter your type of door.
