FIRE RESISTANCE

Cellulose fibre will not melt or degrade when exposed to flame or high temperatures

Cellulose fibre insulation has been treated with Borates for fire retardancy. It will only char under direct fire exposure and will provide longer heat protection to adjacent building materials. It has a Class 1 Fire Rating where flame spread is <25 and smoke development is <50. It is important to note that when cellulose fibre burns, it does not emit toxic chemicals.

C

>60 mins

Cellulose Insulation provides at least 1hr firewall for safer escape

F

<30 mins

Fibreglass will burn hotter and quicker reducing the window of safe exit.

Why it is Important

Under some fire conditions, cellulose gives building occupants more time to reach safety and fire fighters more time to save the structure.

Building Insulation Fire Tests For Cellulose & Fibreglas is a CIMA independent study of fire control properties in buildings with cellulose insulation and fibreglass insulation.

How it works

Natural resistance to heat

Cellulose fibre is naturally resistant to heat and will not melt or degrade as most other insulation will when exposed to flame or high temperatures.

Because cellulose fibre will only char under direct fire exposure it will provide longer heat protection to adjacent building materials, and therefore allow building occupants more time to escape than would be the case with most other insulation materials.

Cellulose fibre insulation products are rated at Class I. In several demonstration burns, buildings with cellulose have retained structural integrity significantly longer than buildings with alternate insulation products. The video from CIMA, provided here, is a pretty powerful incentive to use cellulose over fibreglass.

More Technical Information

Thermal Resistivity

Cellulose Insulation provides greater energy savings over other products.

Convection Properties

Cellulose fibre, due to its perfect fit and greater density, inhibits air movement.

Acoustical Properties

Superior properties for improving noise suppression in wall, floor or ceiling construction

Moisture Resistance

Cellulose fibre has the unique ability to slowly absorb and dissipate excess moisture.

Fire Resistance

Cellulose fibre will not melt or degrade when exposed to flame or high temperatures.

Borate Additives

Cellulose fibre insulation is treated with a carefully controlled blend of borate powders.
