Frequently Asked Questions

How are aerogels made?

The first step in making aerogels is mixing together chemicals in a mold, which quickly forms into an almost Jell-O-like consistency (it has already formed into the aerogel nanostructure, but it is saturated with solvent; it’s wet). It is then rinsed to remove any impurities. The final step is drying it in a specially designed oven called a critical point dryer. The solid sheet of aerogel that emerges from the dryer is used to create a coated glass product that is fabricated into an aerogel-insulated window.

Does AeroShield make windows?

AeroShield is partnering with major window and door manufacturers to incorporate our technology into the brands you know and trust. We are developing aerogel-insulated glass that can be incorporated into the window manufacturing process.

Is it toxic?

No. The aerogel we make is made from silica, similar to the silica desiccant packets that keep products dry during shipment, including food.

Is it a gel or a liquid?

This can be confusing. When we finish making our aerogel, it’s a solid and clear sheet you can hold in your hands. The name “aerogel” refers to the material’s gel state before drying into a super-light and transparent sheet.

Can you spray it directly onto glass?

No, the AeroShield process produces sheets of the material that we bond to glass, creating an aerogel-coated glass product that is far more insulating than standard and Low-E glass.

What certifications or testing has it passed?

AeroShield material has passed many of the required tests for NFRC certification, and we are working with our partners to design final product specifications so our product becomes fully certified and eligible for ENERGY STAR tax credits.

At what stage of development is the technology today?

AeroShield is actively scaling up sizes and production capacity and is completing product design and certification towards the goal of a 2026 launch of our first product.

Is there anything other than windows that your material can be used for?

Besides residential and commercial windows, we look at a wide range of potential uses where transparency, thermal insulation, and light weight are important. Skylights, entry and patio doors, grocery store freezer doors, planes, trains, cars, and more can all benefit from our material.

Where can I buy your aerogel products?

AeroShield is working with partners today to develop, certify, and launch our initial products into the residential market. Product launch is targeted for 2026. Stay tuned for exciting product announcements!

How does your solution compare to vacuum-sealed IGUs?

Vacuum-sealed IGUs can significantly improve a window’s energy savings. However, the cost of this technology is prohibitive, especially for the residential window market. Vacuum-sealed IGUs present added expense and complexities for IGU manufacturers to produce units that maintain their vacuum seal long term. Additionally, many consumers find the visible micro-pillars unacceptable.
