Exceptional Acoustic and Smoke Control

The Lorient Batwing-on-a-stick provides outstanding acoustic door sealing performance, significantly reducing sound transfer between rooms or spaces. Its unique curved fins are precision-engineered to compress effectively as doors close, ensuring optimum acoustic insulation up to 37dB. This makes it ideal for environments requiring confidentiality and noise control, such as offices, hotels, and educational facilities.

In addition, its smoke sealing capabilities meet British Standard BS 476-31.1, ensuring maximum ambient temperature smoke resistance of single action door assemblies. By efficiently minimising gaps around the perimeter, this batwing seal greatly improves the overall resistance of the door assembly, creating a safer environment by preventing smoke infiltration during fires.

For intumescent protection to fire rated doors, install with the Lorient plain fire seal. Select the right width of intumescent strip to provide the required level of fire rating as detailed in the fire door test evidence. 

Innovative Design for Reliable Sealing

Installation is straightforward, with the rigid PVC carrier equipped with a push-fit kerf fixing feature, enabling it to be installed with minimal disruption. Simply cut the seal to the required length and securely press it into place around the perimeter. A 3mm x 9mm groove will need to be routed in the head and jambs. 

Fitted with minimal disruption, this door seal saves time and labour costs, and it is ideal for maintenance or retrofit projects that demand efficient and reliable installation. Always include door seals in your regular door maintenance routine. They should not interfere with the opening or closing resistance of a door. If damaged, replace with a like-for-like Batwing perimeter seal.

Versatile Door Application and Compliance

Engineered for compatibility across a range of door types, this perimeter seal is suitable for both new build projects and existing buildings. The Batwing-on-a-stick design enables easy retrofitting to improve existing doors without extensive alterations. It delivers compliance with acoustic and smoke standards. 

Its slim, unobtrusive profile maintains door aesthetics, providing discreet yet highly effective protection, plus ongoing performance and durability. Other finishes are available on request, including grey, silver, cream, and red.

This perimeter seal effectively minimises the door leaf gap, maintaining consistent sealing performance throughout regular usage cycles. Ideal for environments where reliable and compliant fire door ironmongery is paramount. The flexible elastomeric fin material springs back to original shape to provide ongoing performance. It provides reassurance and practicality for demanding sites and installations, durability tested to 100,000 cycles.
