Aerogel-Lime Floor Insulation: The Modern Twist on Ancient Roman Floors
Looking for a floor that combines timeless charm, energy efficiency, and durability? Aerogel floor insulation, combined with Venetian lime flooring, offers the perfect solution for a warm, breathable, and sustainable home. Inspired by ancient Roman techniques, this flooring system retains heat, regulates moisture, and enhances overall comfort.
High-Performance Insulated Lime Floor System
1. Heat Storage Screed for Cozy Living
At the heart of this system is Massetto Caldo, a lime-based screed with crushed bricks (cocciopesto). These tiny fragments store heat effectively, making your floors warmer to the touch—even without underfloor heating. Combined with underfloor heating, you get a heat reservoir that stays warm longer, saving energy and reducing costs.
- Energy Efficiency: Cocciopesto floors are 16% more energy efficient than cement-based alternatives.
- Heat Retention: Designed to retain warmth for long-lasting comfort.

2. Reflective Insulation with Aerogel Technology
Aerogel, the lightest known solid, revolutionises insulation technology. When combined with lime mortars, it creates a super-insulating lime product with exceptional thermal performance. Applying Termointonaco 2020 MGN (for insulation thicknesses of 30mm or more) or Termorasante Aerogel MGN (for slim-profile reflective insulation) ensures that heat stays in the room.
- Ultra-Thin Insulation: Just 10 mm of aerogel-enhanced lime insulation can make all the difference.
- Heat Reflectance: Reflects heat back into the room, providing exceptional thermal comfort.
- Breathability: There is no other material that would meet modern insulation standards in a traditional breathable lime floor system.

3. Roman Waterproofing for Peace of Mind
No one wants water creeping in from below. A base coat like Rinzaffo MGN serves as a waterproof and salt-resistant barrier, offering a durable and effective solution against rising damp and moisture infiltration.

How It All Comes Together
The strength of this system lies in its carefully designed layers, applied in the following order:
- Moisture-Resistant Protective Base: Rinzaffo MGN prevents rising damp and keeps the floor dry.
- Reflective Aerogel-Lime Insulation: Termointonaco 2020 or Termorasante Aerogel provides exceptional thermal performance.
- Heat-Storing Screed: Massetto Caldo acts as a thermal reservoir, enhancing warmth and energy efficiency.”
The Science Behind It

Lab tests prove that lime floors with cocciopesto outperform traditional cement floors in heat retention and energy efficiency.
Key findings:
- Steeper heat curve for cocciopesto.
- ~16% more heat output compared to cement floors.
- Faster warming and reduced energy requirements.
Ideal Applications
Aerogel floor insulation suits a variety of settings:
- New floor installations.
- Upgrades over limecrete, timber, or cement bases.
- Homes with underfloor heating systems.
- Traditional or modern interiors, from Venetian elegance to rustic charm.
