40% of energy consumption and 36% CO2 emissions in Europe are directly related to the buildings due mainly to inecient insulation materials and systems. Currently required insulation performance may only be achieved either by installing extremely thick ordinary insulation materials and sacricing living spaces or by using unaordable the state-of-the-art insulation materials (e.g. silica aerogel). Of European building sector, more than 99% are SME and buildings construction market reached over 1 trillion equivalent to about 9% of European GDP, representing a total workforce of 25
The ICECLAY project aims at creating a new generation of low cost and most ecient insulation materials for EU building construction and hence enhancing the competitiveness of SMEs in EU construction sector. The project is to develop nano-structured ultra-lightweight clay-aerogel and its integrated composites by using harmless and inexpensive nano-scale minerals, water and eco-friendly or soluble/dispersible low-cost polymers, through innovative and cost eective freeze-drying processes.
The ICECLAY will provide, due to their extremely porous structure and reduced thickness, the superior thermal insulation specially designed for highly energy eciency buildings retrot and advanced HVAC systems. The developed innovative thin and exible lightweight ICECLAY board and lm will claim to be an excellent and
cheaper alternative to the unaordable high-performance insulation materials like the space oriented supercritical-dried silica aerogel and vacuum insulation panels.
The developed powder based ICECLAY will be used as superior enhancing thermal insulation llers for a broad range of building products like concrete, drywalls, bricks, plasters and coatings.
- Harmless and inexpensive raw materials (e.g. natural occurring nanoclays, water and biopolymers).
- A versatile and environmentally- benign freeze- drying process.
Capable of having:
- Very low densities and thermal conductivities, comparable to standard silica aerogels and xerogels.
- Better exibility, less fragileness and brittleness than common aerogels (similar to foam polymers).
- Superior versatility for many applications (tailored by altering composition/production set-ups).
- Good acoustic properties, moisture and re resistance skills.
- Superior environmental ranks (chemical inert and fully recyclable).
- No need for protective equipment to handle.
- Acceptable prices by having lower processing costs (up to 50% reduction againts aerogel's supercritical CO2 drying)- reduce pay-back time investment.
