         Fleece Backed Membranes                       Advantages of Fleece Backed Membranes


                                                       • Increased puncture and hail resistance
                                                       • Improved uplift resistance
                                                       • Use of low-rise foam adhesive is VOC compliant
                                                         and acceptable for use in all markets (including
                                                         California)
                                                       • Excellent re-cover option (non-invasive to
                                                         occupied space)




Advantages of Fleece Backed Membranes


• Use of low-rise foam adhesive for insulation
  attachment will eliminate mechanical fasteners
  which decrease insulation value. (NRCA
  estimates 3% - 8% loss in value)


• Use of low rise foam adhesive will seal insulation
  joints and improve thermal efficiency (up to 10%)
