Welding Blanket Roll 150 ft

The Hi Temp UN51-39-24 is a fiberglass welding blanket roll measuring 150 feet in length and 39 inches in width. It provides a continuous protective barrier for work areas during hot-work operations. The material weighs 24 ounces per square yard and is rated for medium-duty use. It suits welders and fabricators needing long runs of coverage.

Uncoated fiberglass for custom cutting

The roll arrives without grommets or fasteners, allowing the user to cut exact lengths and secure the material as the job requires. An uncoated surface means the fiberglass can be clamped, weighted or taped directly to fixtures. The 0.74 mm thickness drapes over irregular shapes while resisting slag and spatter. No pre-installed hardware limits layout flexibility.

Sustained heat resistance to 1,000 °F

The fiberglass construction withstands continuous exposure up to 1,000 degrees Fahrenheit without degrading. Under prolonged welding or cutting, the blanket maintains its integrity and does not melt or ignite. Medium-duty rating indicates it handles repeated daily use in fabrication shops. It is not designed for extreme multi-layer stacking or direct flame impingement beyond the rated temperature.

Questions about this item

At what temperature does the 24 oz/sq yd fiberglass blanket reach its 1,000 °F limit under sustained welding heat?

The blanket is rated for continuous exposure up to 1,000 °F; beyond that the uncoated fiberglass can degrade and lose protective performance.

How much heat does the 0.74 mm thick roll radiate back toward the operator during an all-day job?

The medium-duty fiberglass reflects much of the radiant heat rather than absorbing it, keeping the work area cooler during extended use.

What mounting hardware must I already have since the 150 ft roll ships with no grommets or fasteners?

You will need your own clamps, wire, magnets or a frame to secure the blanket because the roll has no grommet holes and no fasteners are included.
