	Firwin Plus

Firwin Plus uses a patented technology that manufactures high temperature insulation wool with low bio-persistence.

Firwin Plus is an Alkaline Earth Silicate (CAS number: 329211-92-9) offering the same benefits as our standard FWN 1800 but with improved handling strength and enhanced thermal properties.

Firwin Plus

Manufactured from pure raw materials using a new manufacturing technology
Enhanced thermal properties; large nuisance dust particles have been effectively eliminated making the product soft to the touch and less irritating during use
Made of long AES fibers
Same chemical formulation as Firwin 1800
Outstanding insulating properties at elevated temperatures
Offers excellent thermal stability
Retains its original soft fibrous structure up to its maximum continuous use temperature
Needled from both sides and possesses high strength, before and after heating
Contains neither binder nor lubricant and does not emit any fumes or smell during the first firing
Flexible, easy to cut and shape and easy to install
Low heat storage
Good resistance to tearing
Immune to thermal shock
Good sound absorption
Exonerated from any carcinogenic classification under note Q of directive 97/69EC 6
