Flame Retardant Poly Tarps

Our Flame Retardant Poly Tarps are made in the USA from 3-ply woven reinforced polyethylene at a true 11–12 mil thickness. They are flame retardant, waterproof, and UV-coated on both sides — the lightweight, economical fire retardant tarp option for jobs where a fire-rated cover is required but a heavy vinyl tarp is more than you need. Finished in off-white with rustproof grommets approximately every 2 ft on all four sides, they ship in sizes from 6′ × 8′ up to 100′ × 100′.

What Is a Flame Retardant Poly Tarp?

A flame retardant poly tarp is a polyethylene tarp treated so it resists ignition and is self-extinguishing — it slows and stops flame spread rather than feeding it. It is flame/fire retardant, not fireproof: it will not survive direct, sustained flame, but it meets the fire-rated requirement common on construction sites, in venues, and around equipment. It is the poly (plastic) alternative to heavier fire retardant vinyl tarps.

FR Poly vs FR Vinyl — Which Should You Choose?

The main fire retardant decision is poly vs vinyl. FR poly is lighter and far more economical; FR vinyl-laminated polyester is heavier and more durable for demanding, long-term use. Choose based on weight, lifespan, and budget:

Option	Material	Weight	Best for
Flame Retardant Poly Tarps (this collection)	3-ply woven reinforced poly	11–12 mil, 5.6 oz — lightweight	Construction, roof, equipment & site covers needing an economical FR tarp
13 oz FR Vinyl Laminated Polyester	FR vinyl laminated polyester	13 oz — light vinyl	Curtains & enclosures needing a true vinyl FR
18 oz FR Vinyl Laminated Polyester	FR vinyl laminated polyester	18 oz — mid vinyl	Heavier-duty FR tarps, tents & containment

Frequently Asked Questions

Are flame retardant poly tarps fireproof or fire retardant?

They are flame/fire retardant, not fireproof. The polyethylene is treated so it resists ignition and is self-extinguishing, meaning it slows and stops flame spread instead of feeding it. It will not survive direct, sustained flame, but it meets the fire-rated requirement common on construction sites, in venues, and around equipment.

FR poly vs FR vinyl - which should I choose?

Choose flame retardant poly when you want a lightweight, economical fire-rated tarp for construction, roof, equipment, and site covers. Choose FR vinyl-laminated polyester (13, 18, 22, 27, or 32 oz) when you need a heavier, more durable cover for demanding or long-term use. In short: FR poly wins on price and weight; FR vinyl wins on durability.

Where are flame retardant tarps required or commonly used?

Fire retardant tarps are commonly required on construction sites, in event venues, near welding or hot work, and around equipment and machinery where local fire codes or insurers require fire-rated covers. They are also used for environmental site protection and as divider curtains and partitions.

How thick and heavy duty are these flame retardant poly tarps?

They are a true 11-12 mil and 5.6 oz per square yard, made from 3-ply woven reinforced polyethylene with a 14 x 14 weave. We measure thickness honestly and do not inflate the mil rating.

Are flame retardant poly tarps waterproof and UV-protected?

Yes. They are waterproof and UV-coated on both sides for longer outdoor life, and they are mildew and rot resistant.

What color are they, and do they have grommets?

They are off-white / pale yellow and have rustproof grommets spaced approximately every 2 ft on all four sides for secure tie-downs.
