Tenmat gains approval for Queen’s Award winning Ventilation Firestop Systems

Tenmat 109 vent duct fire sleeve Tenmat Firefly 109 vent duct sleeve’s fire test
Tenmat have long been at the forefront of the development and manufacture of the latest firestopping products for both commercial and residential buildings around the world. This is recognised with Tenmat winning the prestigious Queen’s Award for Innovation for a range of firestopping products including the renowned Tenmat Firefly 109 Vent Duct Fire Sleeves.
There have been recent and dramatic changes in how fire protection for ventilation ducting is specified. This is due to the latest European Fire Test Standards which require the testing to be done taking into account not only the specific type and thickness of vent duct material but also the application which it is used in. This has resulted in the fire testing to be undertaken on very thin wall thickness ducting with the ducting left completely open, known as the Uncapped/Uncapped configuration. This is much more onerous than previous testing as the thin duct material softens and collapses within seconds and the fire is forced much more rapidly along the open duct causing rapid failure.
These latest requirements have made most existing firestop solutions obsolete for PVC vent ducting. Testing on many other solutions has often been undertaken on closed (unventilated) pipe made from much thicker PVC which is much less onerous and not representative of the final application. Tenmat Firefly 109 Fire Sleeves meet the most onerous of the new test standards.
With the increase in the use of controlled ventilation systems resulting in greater penetrations through walls and floors, Building Control are becoming ever more conscious of the need to correctly firestop all ventilation ductwork as it often offers an unrestricted pathway for both fire and smoke around a building.
But it is not just having the correct products, Tenmat work very closely with its partners to ensure that they receive the optimum technical support.

Tenmat have recently worked closely with Vent-Axia on a number of highly prestigious projects including the ventilation systems for athlete’s accommodation. Initially it was found that the fire test data submitted by other manufacturers did not meet the specific project criteria required or the latest fire test requirements. In addition, a significant amount of ‘project specific’ testing was required.
Unlike many manufacturers Tenmat and Vent-Axia embrace the need for project specific testing as this gives both Building Control and the building owners the full reassurance that the testing is 100% correct for that exact construction. In the process of the testing it quickly became apparent that many of the products on the market are simply not capable of meeting these most onerous standards and rapid failure was shown.
Following this experience both Tenmat and Vent-Axia look forward to working together on many more projects and offering a service and peace of mind which other suppliers find very difficult to match.

Tenmat will continue to offer the same level of service and support with the rest of its Award winning range of products including Ventilated Fire Barriers for wall cavities. Tenmat offer an unrivalled level of test data for many wall construction types including timber systems and insulated wall cavities. These systems replace cavity socks and negate the need for cavity drip trays, air bricks and weep holes in external walls. This allows the wall cavity to operate at maximum efficiency with a minimum amount of thermal and moisture bridging, making them both highly cost effective and a popular choice with architects who want the most efficient wall constructions and fewer unsightly penetrations on the wall.
