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.

Prevent trapped fingers in doors and avoid costly legal action

August 19, 2014 13:11 by Jamie B

Every year, according to the Royal Society for the Prevention of Accidents (ROSPA,) 30,000 children trap and seriously crush their fingers in doors at home, school, nursery or shops.

It is also estimated that more than 1,500 of these children will need surgery, sometimes requiring ongoing reconstructive surgery, while some injuries can be as commonplace as bruising and can be treated with ice and cuddles.

It is an unavoidable fact of modern life, we live in an increasingly litigious society. Organisations, particularly customer- or public-facing, leave themselves open to personal injury claims if they cannot demonstrate that they have done as much as possible to avoid accidents.

Law firms claim that the loss of a finger could be worth acclaim in the region of £8,000-£12,000, not to mention the potential adverse publicity that comes with such claims. Reputation management and health and safety are both things that need preventative action to be taken, instead of dealing with a crisis once it occurs.

So what can be done? At Norsound, we don’t just specialise in sound proofing. We also have a variety of door finger protection solutions to suit a range of door requirements.

From retro-fit to fully integrated finger protection, there is a solution for any budget. 

Keeping the sound in

July 11, 2014 12:29 by Jamie B

We recently blogged about the importance of controlling the way sound carries in the workplace – as noise is one of the most distractive influences in the workplace.

But it’s not just the threat of distraction and the loss of that employers should worry about: noise escaping through doors and walls can mean a lack of privacy, too.

This note (pictured) was recently spotted in a workplace's communal kitchen, and shows how easily the wrong people can hear the wrong things. It must be stressed that the employer involved here is not a client of Norsound's!

Whether the information is business critical, confidential, or personally sensitive, such as HR issues, sound proofing is essential to ensure the right things are kept private.

Norsound's acoustic door seals can form an effective barrier to noise that meet’s today's strict regulations and can stop the wrong information escaping.
