What makes X-Treme Board™ Green?

  •  
    • Compared to conventional cementitious backer boards, X-Treme Board requires less than half the energy to produce, making a much lower carbon impact on the environment.
    • X-Treme Board™ weighs less than conventional backer boards, meaning more material can be shipped per truckload, again lowering the carbon footprint.
    • 100% of the post-industrial waste in the X-Treme Board™ plant is recycled into future production runs, reducing landfill impact. External recycled content is also added. The total of post-industrial recycled content is certified at 30%. LEED credits accept 50% of post-industrial waste, making the LEED content 15%.
    • X-Treme Board™ contains no harmful ingredients such as VOCs, formaldehyde, asbestos, or silica dust, and it will not grow mold or mildew. It contributes to a healthier indoor environment.
    • X-Treme Board™ contains no ingredients that are harmful to the planet when it is disposed of. The natural materials in X-Treme Board™ scraps are completely inert.

Does X-Treme Board™ qualify for LEED or NAHB GreenBuild credits?
X-Treme Board™ has been submitted in LEED project documents for contribution to the following LEED credits:

MR 4.1 Recycled Content.
X-Treme Board™ contains a total of 15% recycled materials by LEED formula. 0% is post-consumer, 3% is pre-consumer from outside sources, and 27% is recycled post-manufacture from within the manufacturing process. 3% + 27% = 30% post-industrial. 50% of post-industrial recycled content for LEED purposes is 15% of total material content by volume, and by value.

MR 2.1 or 2.2   Construction Waste Management
Reduction of waste materials (2.1 = 50% reduction, 2.2= 75% reduction)
X-Treme Board™ has no toxic components. (SEE MSDS)[hotlink to MSDS download]. The PH of ground-up X-Treme Board is between 8.0 and 9.0. This allows it to be used as a soil conditioner. It may be used to improve an acid soil on site or off site. X-Treme Board™ scraps are accepted at recycling centers that recycle building materials.

Minimum EQ contribution EQ   3.1   Construction Plan for Low-Emitting materials
X-Treme Board™ contains no silica, no formaldehyde, no asbestos, and is rated under ASTM D3273 as non-nutrient for mold and fungus. It is not harmful for installers, and contributes no harmful substances to the environment.

NAHB GreenBuild® credits
X-Treme Board™ has been used in an award winning NAHB GreenBuild® home. X-Treme Board™ may be included in GreenBuild® credits for recycling and recycled content and for innovation in materials.

What face goes up.
Install X-Treme Board™ with the rough side exposed for installation of tile on countertops,walls, and floors. Install X-Treme Board™ with the smooth side exposed as an underlayment for cork, vct tiles, etc. X-Treme Board™ should not be installed under sheet vinyl goods. Check with the manufacturer of the finish floor materials to be sure they are compatible with cementitious underlayments.

Does X-Treme Board™ have a warranty?
The X-Treme Board™ transferable warranty is the strongest in the industry. You can read it or print it here on the X-Treme Board™ website.

Can I use X-Treme Board as a replacement for drywall?
X-Treme Board™ has been successfully used as a replacement for drywall in homes for individuals with MCS (multiple chemical sensitivities) and those seeking an installation that “breathes”. When installing X-Treme Board™ as a wallboard, seal the board with a non-toxic penetrating sealer before filling and coating the joints. Fill the joints between boards with non-shrinking, quick drying filling cement. Users report that paper joint tape works better than mesh tape for avoiding hairline cracks.

If using earth or lime plasters, test a sealed area of X-Treme Board™ for compatibility before proceeding with a complete installation. Do not apply wet plasters to unsealed X-Treme Board™. X-Treme Board™ is non-combustible and produces no flame or smoke when exposed to fire.  (see the X-Treme Board™ technical guide for test results) X-Treme Board™ does not have “fire ratings” for commercial installations. Check local building codes to ensure compliance before installing X-Treme Board™.
