Transparent Bubble Wrap Promises Fireproof Insulation
15 Dec, 2025
Summary
- New fireproof, transparent gel named MOCHI insulates exceptionally well.
- MOCHI could be applied to windows to drastically improve building energy efficiency.
- The material is mostly air, trapping heat and reflecting minimal light.

A revolutionary transparent gel, dubbed MOCHI, has been developed by physicists at the University of Colorado Boulder, offering a potential solution to the significant heat loss from buildings. This material, resembling bubble wrap, is nearly transparent and possesses remarkable insulating properties, capable of withstanding direct flame contact without transferring heat. Its unique structure, composed of tiny air-filled pores, effectively traps thermal energy, mirroring advanced insulation techniques.
