Air, Acoustic, Fire Sealing and Stopping

If you have air / acoustic sealing or fire stopping requirements, HRS have been specialising in these fields since 1995. What makes HRS different to many other companies, is that HRS use FIRAS and IRATA trained rope access sealers to enable them to air seal and fire stop your building in a fast, safe and cost-effective manner. In many cases the work can be carried out while the building is in use.

Air Sealing Consultants in the UK

In addition to HRS’s extensive knowledge and experience in these fields, HRS can provide you with non-standard ways to air / acoustic seal and fire stop. By using IRATA trained rope access sealers, we can get to the hard to reach places with ease.

The quality of HRS’s work is proven by being a leading supermarket preferred air sealing company since 1995 and a large portion of HRS’s work comes from repeat work and recommendations from contractors.

Since the introduction of Part L in 2002, HRS air sealing teams have become more involved in the air sealing of new buildings. By having the extensive knowledge and experience of working in the retail market for many years, it was an easy task for HRS to be able to provide air sealing and fire stopping services to contractors working on schools, hospitals etc.

HRS often now form an integral part of the project team from providing air testing design reviews and site advice visits to air sealing and fire stopping works to HRS carrying out the air tightness testing.
