Most insulation facings used in metal buildings are available in only two color finishes–white or black. In a metal shed, moisture is the enemy. Fiberglass and other traditional insulations for metal buildings resist heat loss by conduction and convection but has little effect on radiant heat gain/loss. Some versions of batt insulation have a radiant barrier backing. We’ll take a look at the cost of various insulations using an average of R-13 per square foot.
