ECB® Green Literature:     Product Data     Installation     Specifications     SDS     Warranty

ECB GREEN  is a self-bonding, sheet applied elastomeric membrane composed of a minimum of 12% recycled material, and is designed for use in LEED certified projects under floor surfaces that require protection from structural movement.


How It Works

ECB® Green consists of a base layer of polymer modified elastomers, permanently laminated to a recycled plastic "stress flex" fiber sheet. Together they form a single 40 mil (aprox. 1/16") high strength, self-bonding membrane that is easily applied. The elastomeric base layer functions as a buffer, absorbing the thermal and structural movement of the sub-floor, while its recycled "stress flex" fiber sheet creates a new flooring surface which will accommodate most mortars, organic adhesives and epoxy setting materials meeting ANSI A118.4.


ECB Green protects tile from structural movement (up to 3/8" lateral movement), live and dead loads (Rated "Extra Heavy Duty), and provides and effective barrier agaqinst radon, mold and asbestos.  ECB Green adheres permanently to the sub-floor, remains flexible and will last the life of the flooring.



Use ECB® Green membrane OVER:


Concrete: Poured, pre-stressed and pre-cast concrete, concrete backerboard, mud beds, gypsum, lightweight concrete and patching compounds. 


Wood: Exterior or exposure 1 plywood, APA-rated sheathing, Sturd-I-Floor, hardwood, tongue and groove and OSB with standard face. (Gap between sheeting as required.) 


Other Substrates: Ceramic and porcelain tile, stone, terrazzo, VCT/VAT, metal, painted and sealed floors and floors damaged by dry shrinkage and structural movement. 


Use ECB® Green UNDER:


Thin & medium-bed mortar installations (ANSI A118.4) of ceramic, porcelain, stone, marble, slate, granite tile, pavers, brick, hardwood, manufactured wood, commercial grade vinyl and other finished floors; check with flooring manufacturer.


Ideal for use with radiant heated floors and low voltage tile warming systems.


The appropriate NAC Primer must be used to achieve the full benefits of the NAC membrane system and to qualify for a warranty.



ECB® Green is available in 3'x50' rolls (150 sq.ft.)
