DEI Ultra Block Reflective Material - 48in x 48in

DEI is known for making parts that help manage heat and sound in vehicles. Their Ultra Block material is a prime example, acting as a strong barrier against extreme temperatures and unwanted noise. If you're looking to make a generator box quieter, or shield your engine bay from intense heat, this material is designed to handle those tough jobs. It’s also a solid choice for any area where you need to reduce both heat and sound.

What makes Ultra Block work so well is its construction: a lightweight, open-cell acoustic foam paired with a reflective Mylar face. This Mylar layer is key, as it can reflect heat away, handling temperatures up to 428°F. Beyond just heat, the foam itself is built to absorb sound, making enclosed spaces much more comfortable. It also has good resistance to catching fire, meeting specific aviation safety standards. Installation is straightforward thanks to an aggressive adhesive backing, so you can just peel and stick it where you need it.
