Advantages:
Duro-Last
membrane is an excellent choice for projects requiring
a long lasting roofing membrane. The combination of
fleece and the proven performance of Duro-Last
roofing membrane results in an ideal product for use in
adhered and mechanically attached applications over
a wide variety of roof substrates. The complete line of
Duro-Last custom prefabricated accessories is
compatible with the Duro-Fleece Colors membrane.
Description:
In addition to the fleece, DFC60 membrane
incorporates a weft insertion knitted scrim within PVC
films to provide exceptional strength and
waterproofing.
PVC Film - Proprietary thermoplastic PVC
formulation of resins, plasticizers, stabilizers,
biocides, flame retardants, and U.V. absorbents.
Scrim - An 18 x 9 polyester fabric construction
composed of 840 x 1000 denier threads provides
superior tear and puncture resistance. The polyester
thread is treated to prevent wicking.
Fleece - The 3.8 ounce per square yard needlepunched polypropylene fleece provides excellent
properties for adhering to, or mechanically attaching
over, a variety of substrates. Each roll of membrane
has one selvage edge where the fleece is held back
3 inches to provide for hot-air welding to the
underlying membrane.
