1. HEALTH WELLBEING AND SUSTAINABILITY
All of Clayworks natural clay plaster wall coverings share a comprehensive list of benefits and outstanding environmental credentials which sets them apart from other similar products on the market.
2. EMBODIED CO2 COMPARISONS
Embodied CO2 is a measure of the CO2 and other greenhouse gasses released in the extraction, transportation and production of a product or material. Clay plasters are very low carbon materials, due to the local extraction of materials and low energy processing required to produce the products. Clay plasters have one of the lowest embodied CO2 out of any interior finishes. And with clay’s UV stability and repairability the recurring embodied CO2 associated with refurbishment is also kept to a minimum.
3. IMPACT RESISTANCE
As there is currently no standard for testing the performance of clay plasters the impact resistance of Clayworks products was tested to BS EN 520, the standard for gypsum plasterboards. The impact resistance test drops a standard weight and measures the diameter of impact.
Clayworks clay plasters achieved a surface hardness equivalent to Type I (enhanced surface hardness) plasterboard, with an average impact diameter less than 15mm. The performance was identical to gypsum rendered plasterboard tested in parallel.
IMPACT TEST: BS EN 520
4. EMBODIED ENERGY COMPARISON OF TYPICAL BUILD UPS FOR CLAY PLASTERS AND STANDARD GYPSUM EQUIVALENT.
5. RELATIVE HUMIDITY
For optimum comfort and a healthy indoor environment humidity levels should be maintained between 30 – 70%. Clay plasters naturally help maintain these levels minimising mold and fungal growth within buildings.
6. AVAILABLE DAILY WATER ABSORPTION
Clay is one of the best materials suitable for wall finishes with regards to hygroscopic behaviour.
