How do I attach this heat shield?

This Form-A-Shield does not have an adhesive backing. You can secure it using straps, clamps, or DEI Locking Ties. For non-hot areas where you want a heat barrier or reflector, DEI recommends using their Adhesive Spray.

What kind of heat can this shield handle?

Form-A-Shield is designed to withstand direct heat of up to 1400 degrees Fahrenheit. It's effective at reducing radiant exhaust temperatures from components like headers, manifolds, turbo housings, and downpipes.

Can this material be used on the interior of a vehicle?

Yes, its pliability makes it suitable for applications like firewalls and transmission tunnels. It helps lower under-hood temperatures and keeps more heat within the exhaust system.

Product Details

What you get here is a 21-inch by 48-inch sheet of DEI's Form-A-Shield material. This is a serious heat barrier designed to handle extreme temperatures, up to 1400 degrees Fahrenheit directly on its surface. It's made from a 10-mil layer of aluminum bonded to a thick basalt mat, giving it a lot of flexibility to conform to different shapes.

This material is really useful for keeping radiant heat from your exhaust system from cooking the surrounding components. You can apply it directly to hot surfaces like exhaust headers, turbo housings, or downpipes to lower under-hood temperatures. It's also resistant to oil and chemical spills, making it a durable choice for tough environments. Since it doesn't have an adhesive backing, you'll secure it using straps, clamps, or DEI's locking ties, which gives you flexibility in how you mount it.

Because it's so pliable, Form-A-Shield works well on firewalls, transmission tunnels, or anywhere else exhaust pipes run close by. It's a solid option for keeping heat contained where it belongs, either in the exhaust system or away from sensitive areas.
