About Us

NK Group was formed in June 2000 to produce vehicle sound proofing kits to the after care market, trading under the name Noisekiller working with leading UK Acoustic material manufacturers Noisekiller researched designed and developed a range of sound proofing materials that can be used in Vehicle, Marine, Industrial and Domestic markets.

During this time Noisekiller have become an approved supplier to the MOD, Local Government, and the BBC, along with recommendations from the Police and other motoring organisations, we also work with Universities in our thermal division. We have worked with large and small vehicle manufacturers and boat builders and been involved in large and small Industrial projects, to help Companies meet the Noise at Work Regulations. Our latest division Noisy Neighbours has been formed to meet the growth in Domestic noise, in both new and old buildings.

NK Group is proud of its UK manufacturing base and all the products we use in all our divisions are made in the UK, ensuring quick turn round in our production department. We are able to offer a bespoke design service within our range and work closely with designers to meet customer trends and one off requirements.

We have also acquired other businesses and developed new products in the fields of vehicle security, and thermal protection. These divisions have seen NK Group move into ancillary and new markets. Vehicle security is a growing concern for every vehicle owner and our products in that market are recognised as leaders in their field. Our Thermal division formed to meet the demand for protection from heat in the workplace and in University laboratories, along with our latest design the Blazepak carries on our philosophy research design and development of innovative products.
