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
