HVAC Ducting Fireproof Phenolic Foam Insulation Board



Product Description


HVAC Ducting Fireproof Phenolic Foam Insulation Board 


 


Alu foil&stell sheet compoud Phenolic  Panel :     


      Phenolic sandwich Panel  is an excellent alternative to traditional galvanized Iron (sheet metal) duct workand it is ideal for specifications where space or weight is restricted.


     Be used to make the air conditioning heat preservation ventilating duct's material,it widely uses in market,hospital,supermarket, stadium, hotel, workshop, guesthouse, airport, pure project food store, and so on.


     Phenolic foam duct panel offers a high performance, lightweight and robust ductwork system that requires only a single fix installation process.


      Phenolic foam duct panel not only makes it a high speed operation for projects on which time is critical but also provides the advantage of a considerable saving in cost and space. Also Phenolic foam duct panel can make a saving of over 20% on operating cost over a 30 years life.
