The next generation of acoustic drop seal

Specifically designed and manufactured by Norsound in Germany, quality and attention to detail have been at the forefront of every design decision.

Some clever design changes have allowed us to offer our best seal yet.

The robust internal mechanism allows for parallel actuation, whilst a complete overhaul to the seal profile provides for the most durable seal yet, which is even more resistant to seal delamination.

Changes to the actuator allow it to be completely removed from the product when necessary. Not only does this mean that no tools are required in adjusting it, those on site wanting to deactivate the seal when fitting doors can do so very easily. Added to this, the actuator is impregnated with a Teflon material, giving it a smooth surface that eradicates any damage to the frame when the door closes.

The seal comes fully fire tested to comply with British Standard BS476: Part 22 and has a wealth of acoustic data as evidence of its competent sound attenuation properties.

The product is supplied with a pair of brush finished steel end plates.

Screen colour may differ from actual product colour. All technical information is given as guidance only. Due to the technical nature of our products they are designed to be installed by a professional.
