Superior Smoke Protection
This Lorient Batwing perimeter seal actively prevents the passage of smoke in fire situations. Manufactured from high-quality elastomeric material, the distinct 'batwing' fins compress when the door leaf is closed. This compression forms a highly effective barrier, significantly reducing smoke leakage around the perimeter of the door. It effectively seals gaps up to 4mm for single action doors.
The Batwing Seal is smoke tested to BS 476-31.1 standards at an ambient temperature, ensuring dependable smoke containment. This is critical in safeguarding escape routes during a fire incident. To protect at higher temperatures, use the LAS1212, tested at ambient and medium temperature, and effective up to 200°C. Install with separate fire-only intumescent strips on fire rated doors for a complete passive fire seal solution.
Exceptional Acoustic Performance
Noise reduction is increasingly required in buildings such as offices, schools, hotels, and hospitals. This seal provides outstanding acoustic insulation, having been tested to achieve up to 44dB Rw reduction. Its flexible double fin design limits the transfer of noise between spaces. By specifying suitable acoustic door seals, you can effectively manage internal noise pollution and create quieter, more comfortable, and private environments for occupants and users.
Whether for new construction projects or retrofitting existing doors, these high-quality acoustic seals help meet acoustic requirements for residential and commercial buildings, addressing concerns related to acoustic privacy and sound insulation effectively. For door bottom gaps, fit an automatic drop seal like the Lorient LAS8001.
Easy Installation and Versatile Application
Fitting the Lorient Batwing perimeter seal is straightforward. It installs quickly onto the door frame surface with minimal disruption. This makes it ideal for refurbishment projects or busy environments where downtime must be kept to a minimum. With various lengths, finishes, and multiple profiles available (LAS1010, LAS1015, LAS1212), you can select the perfect seal to accommodate different door thicknesses and gap requirements.
Designed with versatility in mind, this smoke and acoustic perimeter seal is suitable for both single and double-leaf doors, offering various application possibilities across differing project specifications. Installation does not require specialist equipment or excessive alterations, ensuring efficient project completion and reliable performance.
From installation, the seal should not impact the effective opening or closing of the door. Check all door seals and fire door ironmongery as part of your regular door maintenance routine. Ensure the seal is in good condition, properly fixed in place, and the door latches properly after each use.
Reliable Protection for Your Facility
When specifying door seals, reliability matters. Lorient Batwing perimeter seals offer robust performance for a range of facilities. Low maintenance and constructed from rigid back PVC with flexible fins, they provide dependable protection, reducing ongoing costs and sealing issues.
By choosing Lorient Batwing smoke and acoustic perimeter seals, you're selecting reliable door hardware that delivers genuine safety, compliance, and acoustic management for your project, ensuring your installations perform effectively and professionally over the long term.
