TENMAT Ventilated Fire Barriers – Preventing fire spread in external cavities

Fires in external cavities of clad buildings are a major issue which appear with ever increasing frequency in the news headlines across the globe. Ventilated cladding systems are an extremely effective method of protecting a structure from the elements and Architects embrace these systems due to the wide range of colours and finishes and the ease of installation. As good as these systems are, they can create a serious fire protection threat to structures and people if not adequately protected. The cavity acts like an open chimney and allows the fire to spread quickly both vertically and horizontally around the building. The fire is often hidden behind the façade and can be extremely difficult to deal with for the Fire Services.

TENMAT manufacture a range of innovative Ventilated Fire Barriers that are designed to maintain the ventilated cavity in normal conditions but will rapidly expand to seal off the cavity in the event of a fire and ensure that the fire is contained.

The range consists of Ventilated Fire Barriers to suit small cavities, such as 10mm render cavities right up to 500mm cavities that can be found in some rainscreen cladding systems. The product range is backed up with extensive third party test evidence to prove that the products are tested in the applications in which they will be installed. The test evidence covers a wide range of constructions, insulation types and cavity sizes.
