Soundproofing doors at BUNN® UK Head Quarters

One of our recent case studies was for BUNN®UK Head Quarters in Solihull. BUNN® are a worldwide manufacturer of dispensed beverage equipment and supply many of the most well know coffee shops across the world.


Office Soundproofing was asked by BUNN® to reduce the noise entering the main office area from the lavatories. Toilet noise is a common soundproofing enquiry we receive from many commercial offices across the UK. The lightweight construction of most modern office interiors does not incorporate soundproofing insulation. Sound will transmit along walls, through lightweight doors and uninsulated suspended ceiling voids will allow noise to travel across the entire office. This is mainly because of cost effective traditional building techniques that do not take into consideration the way sound travels.

At BUNN®UK HQ the solution was to soundproof the noise at source

After a thorough investigation of the problem and a few acoustic tests, it was clear that as well as the walls, the doors would also need upgrading to soundproofing doors. The walls were light weight gypsum based walls and the original doors allowed too much noise to escape into the reception area.

Soundproofing doorThe solution was fairly straight forward with the installation of our 50mm office panel system and two new soundproof doors installed in the reception area, treating the noise problem at source. This minimised the disruption to the main office area and this also saved money as we soundproofed a smaller area. We also treated the conflicting doors with new 64mm thick, 44dBRw acoustic soundproof doors. The main flanking walls were also treated too, in order to reduce vibration down the walls into the main office. Each new soundproofing door required the existing frame removed and a new high spec frame with acoustic seals installed.

Office Soundproofing carried out the complete service for BUNNâ including all the wet plastering, plumbing, painting and decorating. We took colour samples of the existing interior and had paint mixed to match the colour exactly. As well as completing a high quality finish to the interior, the toilet noise was completely eradicated!
