If an unexpected freeze occurs and you have not winterized your backflow you could have costly repairs on your hands. Protect your backflow assembly year round from sudden cold snaps that can occur in early winter or late spring with our FrostGuard™ Insulated blankets. They will blend into your landscape better and offer superior protection to unsightly burlap wrap.
Install the FrostGuard Blanket easily by just slipping it over the assembly; with 9 standard sizes that cover most 1/2" to 8" inline assemblies. They come in 2 choices of industrial grade, resilient, crushable, compressed fiberglass insulation, R-13 or R-30. Our rugged blankets are double stitched and the seams are heat treatred to ensure a solid bond. The heavy 14 oz water repellent vinyl fabric used is UV & mildew resistant and fire retardant to meet NFPA-701 / ASTM E-84. They can be left on year-round for your convenience.
Reinforced grommets on the bottom seams are standard and allow a padlock to be used to lock your FrostGuard in place. Any RP relief valve discharge is unobstructed, even when bottom seams are padlocked together for best insulation protection.
These blankets fit inside of our standard cages & are available in Forest Green or Woodland Tan to compliment your landscaping.
Some cheaper blankets from the competition will quickly begin to decompose in the sun. Our blankets will last season after season.

Features
The outside of the blankets are made of heavy duty, weather repellent, 14oz Vinyl which is UV and mold resistant and meets NFPA-701 ASTM E-84 Standards.
We use environmentally friendly Sustainable Fiberglass Insulation that consists of rapidly renewable content, a high percentage of recycled glass, and a new plant-based binder that has no formaldehyde, harsh acrylics or dyes. Our insulated blankets come in 2 options of insulation values, R13 and R30.
The blankets have heat sealed seams for superior strength & reinforced grommets on the bottom seam. The grommet is used for a padlock to be used to keep the FrostGuard secure and closed for best insulation. Any unexpected RP relief valve discharge can still vent unimpeded out the bottom of the bag.
Standard Colors
Standard colors are in high gloss Woodland Tan & Forest Green which were selected to blend into most any landscaping.
