DRYWALLGREENTECH DRYWALL -- RECYCLED MATERIALS AND PLANT BASED PRODUCTSSERIOUS MATERIALS, INC.ECO-ROCKhttp://www.seriousmaterials.com/html/ecorock.htmlOver 30 billion square feet of drywall are produced each year in the U.S. and Canada. A single sheet uses between 100,000 and 400,000 BTUs of energy to produce, depending on the age of the plant, producing 16 pounds of greenhouse gases per sheet. Approximately one-quarter of the cost of a gypsum drywall panel is tied to energy, with likely long-term cost increases; carbon taxes are common in Europe and may come to the U.S.By contrast, EcoRock uses 80% less energy in the manufacturing of its core. No heaters or dryers are used in production, nor calcining processes – resulting in 80% less CO2. EcoRock also uses 85% post-industrial recycled content and is fully recyclable. A plant built for EcoRock reduces energy use to a minimum.EcoRock will be available in early 2009. Please contact us to discuss availability and timing for your projects, as we expect very heavy demand for initial production quantities. COST: $14 TO 20 PER SHEET PER POPULAR SCIENCE MAG=======================================================================\
THERMAROCK http://www.seriousmaterials.com/html/thermarock.html
ThermaRock XI (eXtreme Insulation) is the first drywall that reduces a building’s energy use for operations. Standard gypsum drywall provides little thermal insulation, with an R value of about 0.5. ThermaRock panels deliver R2.5 to R4.1. This much higher-performance can save up to $1,700 per panel in energy costs over the life of the product. ThermaRock is well-suited for space-saving, energy-efficiency-boosting retrofits. Adding a layer of ThermaRock to an existing exterior wall – whether stud-based or built with cement blocks – can substantially reduce energy costs and improve comfort. The installation process is just like drywall, and far less disruptive – or space-consuming – than building out an interior wall. DATA SHEET: http://www.seriousmaterials.com/TRockXI_dsheet.pdf
