INSULATION CORE: POLYFILL INSULATION
​
SEWING THREAD: DOUBLE-STITCHED UV-RESISTANT NYLON
​
CONSTRUCTION: ALL BACKFLOW BLANKET INSULATION PRODUCTS ARE MANUFACTURED WITH FIRE AND UV-RESISTANT FABRICS TO GIVE YEARS OF OUTDOOR PROTECTION. EACH SEAM IS DOUBLE SEWN TO SEAL OUT ALL WEATHER ELEMENTS. THE SIDE SEAMS OF SOME MODELS HAVE ADDITIONAL RIVETS TO PREVENT SPLITTING. USING THE PRE-INSTALLED GROMMET(S), THE BAG CAN BE SECURED WITH A LOCK TO PREVENT THEFT AND OTHER DAMAGE. GROMMETS AND VELCRO SEAMS CAN ALSO BE INSTALLED FOR DEVICES THAT REQUIRE A PARTIALLY OPEN TOP OR SIDE. ALL OF THE INSULATION USED IN BACKFLOW BLANKET PRODUCTS IS CUT IN WHOLE PIECES TO MINIMIZE GAPS THAT COULD CAUSE FREEZE-UPS.
PROVEN QUALITY: ALL OF OUR BACKFLOW BLANKET PRODUCTS HAVE BEEN TESTED TO MAINTAIN WATER FLOW IN STATIC LINES UP TO 10 HOURS IN ZERO-DEGREE TEMPERATURE*
