Heavy Duty Silver Black Tarps

Heavy duty silver black tarps are reversible 11 mil waterproof poly tarps built for canopy replacement, construction, farm, and roof cover. The reflective silver face throws back sun and heat, while the blackout-black backing fully blocks light — so the same tarp works as a heat-reflective canopy top and a light-tight cover. At a true 11 mil with a tight 14 x 14 weave and 6 oz/sq yd fabric, this is the heaviest of MyTarp's standard heavy-duty poly colors, a clear step up from the 10 mil silver, white, and brown silver tarps. Made by Sigman from 3-ply woven reinforced polyethylene and UV-coated on both sides, it's a favorite for replacing worn carport and canopy covers and for jobsite and equipment protection.

Why choose silver black

At a true 11 mil, the silver black tarp is the heaviest of MyTarp's standard heavy-duty colors — above the 10 mil silver, white, and brown silver tarps and a step below the 12 mil Made-in-USA tier. What sets it apart from the other colors is the blackout-black backing: the silver side reflects heat and UV while the black side blocks light completely, which is why it's a go-to canopy replacement and shade cover. The tight 14 x 14 weave and 6 oz fabric add wear and weather resistance, grommets every 1.5 ft give frequent tie-down points, and bulk multi-packs make it practical for contractors. MyTarp lists the actual measured thickness — the 11 mil you order is the 11 mil you receive.

Frequently Asked Questions

What are heavy duty silver black tarps best used for?

Heavy duty silver black tarps are reversible 11 mil waterproof poly tarps best for canopy replacement, construction and jobsite cover, farm and hay use, and roof and equipment protection. The reflective silver face throws back heat while the blackout-black backing blocks light, so the same tarp works as a heat-reflective top and a light-tight cover.

Are silver black tarps good as a canopy replacement cover?

Yes. At a true 11 mil with a tight 14 x 14 weave, silver black tarps are a popular heavy duty replacement for worn carport and canopy tops. Run the silver side up to reflect heat, use the grommets every 1.5 ft to lash the tarp to the frame, and measure your existing canopy so you can pick a finished size that overlaps the frame on all sides.

Which side goes up on a reversible silver black tarp, silver or black?

Either side can face up. Run the silver side up when you want to reflect sunlight and heat, which keeps the space under a canopy cooler. Run the black side up when you want to block light or want a darker, low-glare look. Both sides have a UV-protective coating, so the tarp is protected whichever way you install it.

Does the black side block light and make a good shade cover?

Yes. The blackout-black backing blocks light fully, which sets silver black apart from the silver, white, and brown silver colors. That makes it a strong choice for shade structures, blackout cover, and any application where you want to keep light out while the silver side still reflects heat on top.

How does an 11 mil tarp compare to 10 mil and 12 mil poly tarps?

At a true 11 mil with 6 oz/sq yd fabric, the silver black tarp is the heaviest of MyTarp's standard heavy-duty poly colors. It is a step up from the 10 mil silver, white, and brown silver tarps and a step below the 12 mil Made-in-USA tier. Choose 11 mil silver black when you want extra weight plus a full light-blocking side; step up to a Made-in-USA tarp when you need the longest service life.

How thick and heavy are silver black tarps?

Silver black tarps are a true 11 mil thick with a 14 x 14 weave count and 6 oz/sq yd fabric weight, made from 3-ply woven reinforced polyethylene and UV-coated on both sides. The tight weave and heavier fabric add wear and weather resistance compared with lighter poly tarps.

What size silver black tarp do I need?

Measure the area or canopy frame you need to cover and allow extra material on each side for overlap and tie-down. Silver black tarps come in 17 finished sizes from 6' x 8' up to 40' x 60', including common canopy sizes like 10' x 20', 12' x 20', and 20' x 20'. Because these are finished-size tarps, the actual size is typically within 1 to 3 inches of the nominal size listed.

Silver black vs heavy duty silver vs Made-in-USA, which should I choose?

Choose 10 mil heavy duty silver for an all-weather, heat-reflective canopy, roof, and equipment cover. Choose 11 mil silver black when you want a heavier tarp with a blackout-black side for canopy replacement and light-blocking shade. Step up to a 12 mil or heavier Made-in-USA poly tarp when you need the longest outdoor service life.
