Fire Proof Blankets

welderColor Swatches

WeldShield welding blankets carry three ratings in degrees Fahrenheit for constant, intermittent and melt. These values will range from 1000 degrees constant to 1800 degree melt. The “constant” rating is intended to define the maximum temperature an object may be at and be in direct contact with the blanket. The “intermittent” rating (also referred to as excursion temp) is what the fabric can take for short exposures without damaging the cloth. The “melting” temp is the point where the fabric is physically damaged due to prolonged exposure to excessive heat. Order Now

WeldShield welding blankets are fabricated with high-temp thread and brass grommets every 2'; they are then individually poly bagged for ease in shipping, storage and handling. All stock sized blankets will run smaller in their finished dimensions by several inches due to the fabric lost in the hemming and seaming operations. Finished sized blankets may be ordered at an upcharge if final dimensions are critical.

Fire Resistant Welding Blankets

WeldShield uncoated Fiberglass Blankets are available in 2 different weights: 18 oz/sy (WeldShield 1890 F-T) and 24 oz/sy (WeldShield 2490 F-W) and are considered by many to be the standard of the industry. WeldShield Fiberglass Blankets deliver the most utility for expense of any welding blanket line on the market today. Special Volume Discounts are offered for larger orders, including free freight!

Emergency Blankets

These fire proof blankets can also serve as a safety device designed to extinguish incipient (starting) fires. Small fire blankets, such as for use in kitchens, dorm rooms, and around the home, can be placed over a fire in order to smother it. Fire proof blankets, along with fire extinguishers, are fire safety items that can be useful in case of a fire.

The three predominant base fabrics are fiberglass, silica and Aramid in ascending order of cost. The fiberglass families of welding blankets are available as uncoated base fabrics (most economical) as well as with a number of different coatings including silicone, neoprene, Hypalon, aluminum, and Vermiculite. The uncoated fiberglass blankets come in two different weights: 18 oz/sy (WeldShield 1890 F-W) and 24 oz/sy (WeldShield 2490 F-W). There is also a 1-side Aluminum coated fiberglass (WeldShield FA-S) that is ideal for heat reflection and direct heat contact.The silicone coated fiberglass is generally used a as curtain for protection against molten metal splash and is good to 500 degrees Fahrenheit (WeldShield 1790 SF-G or 1790 SF-R). The salmon colored Neoprene coated fiberglass in the 17 oz/sy fabric is ideal for use as a grinding shield to contain sparks and splatter with a service temperature to 300 degrees Fahrenheit and a 1000 degree melting temperature and is easy to handle without the scatchiness associated with raw fiberglass (WeldShield 1790 NF-P). The green colored Hypalon coated fiberglass comes in an 18 oz/sy coated fabric weight and is best deployed around oil & grease environments and displays exceptional strength, abrasion & puncture resistance, and low smoke (WeldShield 1890 HF-G). The gold toned Vermiculite coated fiberglass is available in both a 20 oz/sy (WeldShield 2090 VF-G) and a 40 oz/sy (WeldShield 4090 VF-G) and both are more expensive than the rest of the coated fiberglass products but ideal for high temp applications in small confined spaces where other flammables are nearby. A good example of this would be welding or soldering near wood framing.

The Silica cloth Welding Blankets are a mid-priced option with the highest ratings for service, intermittent and melt temperatures. These tan colored fabrics are soft and pliable with a good “hand” and conform easily to any covered object. They can handle constant temperatures to 1800 degrees F, excursions to 2500 degrees and won’t melt until 3000 degrees. They come in two different fabric weights: 18 oz/sy (WeldShield 1890 S-T) and 36 oz/sy (WeldShield 3690 S-T). These blankets are the professional’s choice for severe welding applications involving extremes in heat, slag, welding sparks and molten metal splash.

The Aramid product is available in only one style as a 23 oz/sy black fabric known as Altex 400. The Aramid blend material is a man made fiber typically containing exotic fibers like Kevlar and it has a service temperature to 650 degrees Fahrenheit and displays excellent strength and abrasion resistance. It is considered more durable than standard fiberglass products and is also very flexible with little stretching, offers good chemical and mildew resistance, and is un-affected by most acids and alkali solutions. This is a special order product that requires added leadtime to fulfill most orders.

No matter what your choice, WeldShield Welding Blankets are an excellent value and will give many years of use when used properly. Feel free to contact us with any questions at

In only 3 1/2 minutes, the heat from a house fire can reach over 1100 degrees Fahrenheit.  (Fact Sheets about Injuries and Injury Prevention)

In a home fire, the peak temperature and duration of the fire can vary depending upon the size of the home, the materials used to construct the home, the response time of firefighters, etc. It is estimated that the typical peak temperature in a home fire ranges between 800 to 1200 degrees Fahrenheit. The typical time for firefighting authorities to bring a home fire into containment is estimated at 15 to 30 minutes.
Paper chars at approximately 402°F. To protect paper documents, the internal temperature of a safe must remain below 350°F while exposed to the conditions of the typical home fire. Thus at a minimum, a safe should provide enough fire resistance to keep the maximum internal temperature of the safe below 350°F, when exposed to external temperatures of 1200° for 30 minutes.

Frequently Asked Questions

We have a requirement to put fire blankets around some semi-tires in our application. Our question is around how well does the material stand up to extended exposure to sunlight, water and freeze thaw cycles etc. Is it better to get a coated blanket for the environmental concern? Also after some fire exposure testing we may be requesting custom fit blankets for the longer application. Is that something you can do?

I would go with a coated fabric, either black WeldShield 2190 AF-B or gold WeldShield 2490 AF-G (see column choices 5 & 6 from left side of the table above) can be custom sized by clicking on "custom tarp configurator" link in paragraph above the table of stock sizes. An uncoated fiberglass or silica product could wick moisture and cause early breakdown of the fibers. Sunlight is no factor. As long as you are not talking cryogenic like temperatures, the cold should not have an effect on the blankets once they return to a reasonable temperature. They will get brittle at very low temperatures, below 32 degrees F, but would retain their resistance to slag, sparks, etc.

I'm looking for a welding screen, would these work for this application?

No, we would recommend you take a look at our other site dedicated to Welding Screens.
