Exceptional Acoustic Sealing

The Lorient LAS8003 door bottom seal is rigorously tested for acoustic performance, making it ideal for environments requiring effective noise control. Its automatic sealing action reduces sound transmission through the door threshold, with a 33dB rating. This significantly improves privacy and creates quieter internal spaces. This makes it perfect for commercial buildings, educational spaces, and healthcare facilities, where sound insulation is essential.

Reliable Smoke Containment

Compliance with stringent smoke leakage performance requirements is a must for fire door assemblies, and the Lorient LAS8003 meets these demands. Automatically lowering into place when the door closes, the seal effectively blocks smoke infiltration, ensuring containment during fire emergencies. Where required, fit a threshold plate such as the Lorient LAS4100 for firmer gasket contact.

Preventing smoke from spreading enhances occupant safety and assists building compliance with UK fire regulations. For a complete door sealing solution, install alongside a perimeter seal or a combined intumescent smoke seal like the Lorient Finesse or their DS double fin intumescent strip. Sizes are available to suit 30-minute and 60-minute fire rated doors.

High-Efficiency, Power-Free Operation

The LAS8003 Lorient seal incorporates a high-efficiency mechanism designed to operate smoothly without a power connection. This automatic drop seal engages reliably every time the door is opened and closed, providing consistent sealing action without electricity or any wiring. Its mechanical design ensures reliable, low maintenance use, making it a practical solution suitable for a range of facilities. Check periodically to ensure doors latch correctly and adjust the seal as required.

Versatile and Easy to Fit

Designed for simplicity and versatility, the LAS8003 automated threshold seal is compatible with both right and left-handed doors. It comes in multiple length options, ensuring it suits a wide range of door widths. Each length of seal can be cut down to the next length on site. The exception is the 335mm length which can be cut to 255mm.

Its face-fixed installation method means quick, straightforward fitting with little disruption, saving valuable time during installation or retrofitting. Install on timber doors and ensure the activation button is on the hinge side. Test the product once fitted to make sure it doesn’t affect the closing or opening of the door.

Professional Threshold Protection

The Lorient LAS8003 drop seal delivers professional-grade sealing, effectively combining acoustic insulation, smoke control, and draught and light reduction in a single, reliable solution. With no need for power and easy installation, this seal is a smart investment. Manage acoustics and ensure smoke containment confidently by selecting the right door seal for your project.
