AeroShield manufactures a super-insulating, porous glass for energy efficient windows. Based on one of the most insulating materials in the world, AeroShield is twice as insulating as air and lighter than a marshmallow.

Making windows lighter, thinner, & more comfortable

The AeroShield material can be placed between two panes of glass, similar to a traditional double-pane, to create a product that is 50% more insulating than traditional windows, but with a payback period up to 5 times faster than windows of similar performance. This brings state-of-the-art thermal comfort, durability, and energy savings into homes at a price that consumers can afford.


The AeroShield Material: high clarity silica aerogel

The AeroShield material was developed and patented at MIT to reach the highest clarity. This solid material is made up of 95% gas trapped inside pores that are so small the naked eye can’t see them. It’s these pores that reduce convection, while the glass nanoparticle backbone limits conduction and convection.
