My understanding is that thick bass traps perform better when lower density insulation is used, but how low in density does this actually mean? LBS / Cubic Feet = Density (PCF). Density Example. 40" x 48" x 54" =103,680" 103,680" / 1728 = 60 Cubic Feet 300 LBS / 60 CU. FT. = 5 PCF. Weight (lbs ... With a 2.8 PCF density, it provides thermal insulation for operating temperatures up to 1000ºF for furnaces and more. Applications. High-Temp Equipment. Foam density is measured by dividing the weight of the foam by its volume. This measurement gives us the PCF rating, which helps to gauge the foam's quality and ...
