Abstract

An HVAC airflow duct has a polymeric material that meets UL723 and/or ASTM E84 of at least 25/50 or better and/or maintains or exceeds a minimum insulation value.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
         1 . An HVAC airflow duct, comprising:
 a polymeric material that meets UL723 and/or ASTM E84 of at least 25/50 or better and/or maintains or exceeds a minimum insulation value.   
     
     
         2 . The HVAC airflow duct of  claim 1 , wherein the polymeric material is a foamed material. 
     
     
         3 . The HVAC airflow duct of  claim 1 , wherein the polymeric material is an unfoamed material. 
     
     
         4 . The HVAC airflow duct of  claim 1 , wherein the polymeric material comprises polyetherimide. 
     
     
         5 . The HVAC airflow duct of  claim 1 , wherein the duct comprises a removable panel. 
     
     
         6 . The HVAC airflow duct of  claim 5 , wherein the removable panel comprises the polymeric material that meets UL723 and/or ASTM E84 of at least 25/50 or better and/or maintains or exceeds a minimum insulation value. 
     
     
         7 . The HVAC airflow duct of  claim 5 , wherein the removable panel comprises polyetherimide. 
     
     
         8 . The HVAC airflow duct of  claim 7 , wherein the polyetherimide is foamed. 
     
     
         9 . The HVAC airflow duct of  claim 7 , wherein the polyetherimide is unfoamed. 
     
     
         10 . The HVAC airflow duct of  claim 7 , wherein the panel comprises a hook. 
     
     
         11 . The HVAC airflow duct of  claim 10 , wherein the hook comprises polyetherimide. 
     
     
         12 . The HVAC airflow duct of  claim 11 , wherein the hook is integrally formed with the remainder of the panel. 
     
     
         13 . An HVAC cabinet, comprising:
 an airflow passage at least partially defined by a component comprising a polymeric material that meets UL723 and/or ASTM E84 of at least 25/50 or and/or maintains or exceeds a minimum insulation value.   
     
     
         14 . The HVAC cabinet of  claim 13 , wherein the component is a composite component comprising a skin joined to the component. 
     
     
         15 . The HVAC cabinet of  claim 13 , wherein the component is a removable panel. 
     
     
         16 . The HVAC cabinet of  claim 15 , further comprising:
 a seal carried by the removable panel.   
     
     
         17 . The HVAC cabinet of  claim 15 , further comprising:
 a panel mounting feature carried by the removable panel.   
     
     
         18 . The HVAC cabinet of  claim 17 , wherein the panel mounting feature comprises a hook. 
     
     
         19 . The HVAC cabinet of  claim 17 , wherein the panel mounting feature comprises the polymeric material that meets UL723 and/or ASTM E84 of at least 25/50 or better and/or maintains or exceeds a minimum insulation value. 
     
     
         20 . The HVAC cabinet of  claim 13 , wherein the cabinet further comprises at least one of a furnace cabinet and an evaporator cabinet.
