ClimaVault installation

The science of a resilient envelope.

Our mission is to save lives, money and property in an environmentally responsible way by protecting structures with revolutionary fireproof insulation.

What does ClimaVault™ do that other insulation can’t?

It is a fireproof, inorganic insulation that combines high R-value thermal performance, sound attenuation, pest resistance, zero off-gassing and zero VOCs. Every claim is backed by independent lab testing.

Why aren’t sprinklers and fire-resistant products enough?

They offer marginal protection in a wildfire. Water-based systems fail under extreme conditions and do nothing for contents. Existing structures, historic buildings, museums, schools and hospitals are left exposed.

Why is the problem getting worse?

Conventional insulation releases toxic gases when it chars. California sees thousands of wildfires a year and billions in losses, insurers are leaving, and climate change, water shortages and development expansion compound the risk.

“A ‘green building’ with potentially hazardous insulation isn’t a green building at all.”

"The best chance for a home to survive a wildfire is to prepare the structure to stand alone.... that means a fire can burn through the area without any action by firefighters."
