Product Sector: Construction → Building Materials → Insulation
As energy-efficiency standards for buildings become increasingly stringent, using a traditional insulation material often means having to accept increasingly thick layers of insulation in walls, floors, and roofs. This consumes valuable floor space in new construction. In renovation projects, if it is even possible to increase insulation thickness at all, significant aesthetic and functional compromises are often required to retrofit more insulation on the inside or outside of the building envelope.
Cabot's Nanogel aerogel can help building owners and architects break away from these compromises. With a thermal efficiency that is 2 to 4 times greater than traditional materials such as polystyrene, mineral wool, and cellulose, Nanogel delivers more insulation performance with less thickness. Along with high efficiency windows and daylighting systems, the use of Nanogel in walls, floors, and roofs can help a building meet even the most difficult requirements of the Passive House or LEED Platinum standards.
Performance benefits of Nanogel products in building insulation include:
- Ultra-low thermal conductivity - as low as 15 mW/mK (R-9.6 per inch)
- Hydrophobicity - repels water
- Resists settling
- Superior acoustic insulation
- Durable over time
Nanogel particles, or granules, are especially useful in loose-fill cavity wall applications. Nanogel granules may also be added to plasters and other coating systems to provide thermal insulation.
Nanogel Thermal Wrap blanket is especially useful in applications where a thin product is required that can be easily cut, rolled, and/or shaped on the jobsite. Thermal Wrap is perfect for insulating facades, roofs, and interior walls. Because it delivers high insulation performance even when compressed, it is especially useful as a thermal break in places that otherwise conduct a lot of heat such as over studs and around windows. Finally, in addition to its value as a thermal insulator, the excellent acoustic properties of the Thermal Wrap help attenuate noise from outside the building.
