Fix your face on Norsound's new NOR820 door bottom seal

November 28, 2014 15:52 by Neil S

The latest addition to the NOR800 range of acoustic door bottom seals - the NOR820 has already been a big hit with customers. 

Designed as a retro-fit acoustic seal solution for the bottom of a door, this seal is extremely easy to fit and does not compromise on quality.

Made from T6063 grade aluminium with a silicon insert, the NOR820 provides protection against sound and smoke, whilst also being self-levelling and lightweight in operation. 

As this door bottom seal is a face fix solution asthetics are key. With this in mind the NOR820 comes complete with a slick aluminium clip-in cover plate, which once the seal is fixed in place, completely covers the seal to give a pleasing sight line.

Adjustment is easy to suit gaps up to a maximum drop of 12mm and it comes in a range of sizes (430mm - 1230mm), which cut back up to 100mm to suit the widest range of door applications.

Norsound have already had keen interest in this product with a range of hotels already taking advantage of this quick to fit but very robust acoustic drop seal.

Norsound launches enhanced smoke and acoustic door seal

October 24, 2014 13:03 by Jamie B

Sound proofing specialist Norsound has launched a new, improved perimeter door seal that brings enhanced sound and smoke-proofing to the market.

The NOR710STOP has been designed to provide outstanding acoustic and smoke sealing abilities. The seal will take place among the NOR710 range of acoustic perimeter seals.

Designed to fit into a kerf (saw cut) in the door stop, this perimeter seal can increase the acoustic performance of a standard fire door whilst also providing additional protection against cold smoke.

It consists of a semi-rigid base with two flexible blades of optimum angles, these flexible blades act like triple glazing giving maximum acoustic performance along with smoke seal capabilities and energy saving properties.

The NOR710STOP is unaffected by door furniture including hinges and latches and is also highly durable being tested to 1,000,000 cycle tests.

Benefits of the product include:

  • Sound reduction

  • Protects against smoke

  • BS 476 Pt 31:1 cold smoke

  • 1,000,000 cycle tested

  • Stylish ultra smooth blades

  • Dual Air Pocket Technology


Norsound targets architects and specifiers with acoustic calculator app

October 02, 2014 08:40 by Jamie B

Norsound has launched an app for iOS aimed at helping architects and specifiers to identify the dB rating that an acoustic wall and door would provide.

The Acoustic Calculator is already available on the Norsound website and now has a complementary app for iPhone.

The app takes data from a number of parameters – the width and height of walls and doors, and the decibel rating – to determine the dB rating for acoustic resistance and soundproofing.

The app will be useful for architects, specifiers and anyone else in the construction industry looking for overall acoustic ratings that combine walls and doors.

Norsound offers a range of acoustic door and perimeter seals that offer an effective barrier against noise, while meeting all the very latest regulations.

Note: Acoustic tests have been carried out under scientific conditions by trained acoustic engineers. Norsound can in no way guarantee replication of exact results due to implementation by unknown parties. Owing to the nature of sound, the smallest hole in the seal or indeed the object would seriously impair the overall dB rating of the entire entity as a whole.

Regular updates to enhance the use of the Acoustic Calculator is a huge priority for us and we appreciate the feedback and requests from all our customers.
