element, how are architectural metals  
included in the process, specifically  
metal panels?  
The great thing about metal panels  
is that you can put insulation behind  
them,” says Frank Buccholz, general  
manager of Southern Aluminum Fin-  
ishing (SAF).“Depending on what the  
architect is looking for, there are sev-  
eral types of insulation with different  
R-values.” Polyisocyanurate (polyiso),  
mineral wool and polystyrene are  
unique in their R-values, he continues,  
but with polyiso,the thicker the density  
of the material, the higher its R-value.  
“One inch of polyiso has an R-value  
of 6.5; one inch of mineral wool has an  
R-value of 4.3. That may not seem like  
a lot,” explains Buccholz,“but that’s al-  
most 20 percent more insulation.”  
What’s New
