  1. Progressive Foam Technologies, Inc’s Fullback Insulation
  2. R-values are based on Federal Trade Commission requirements under the ASTM C1363 standard, which provides stringent, repeatable and reproducible results. While R-values for some profiles produced through ASTM C1363 testing may result in lower R-values than simulation modeling, the home insulating performance of insulated siding has not changed. ASTM C1363 testing provides added assurance of its energy efficiency performance and R-value results.
  3. PREVENTOL® TM is a registered trademark of Progressive Foam Technologies, Inc.
  4. Windload testing is based upon ASTM 5206 testing and the results are reported per ASTM 3679 section 5.11. Florida Building Code FL#1712.5

Maximum Impact Resistance

Unlike conventional hollow siding, CedarMAX Insulated Siding gives a solid foundation of support against rain, hail or your child’s fastball. The rigid foam offers 5 times greater impact resistance over hollow siding.
