(measures exactly 59" x 100')Heavy Duty 9 mil Fabric ThicknessBright Reflective Silver Coating one Side / Super Tough and Durable Ballistic Nylon on the other.HIGHLY REFLECTIVE SILVER TEXTURED SURFACES!Easy to use ROLL! Also used to LINE GROW ROOM WALLS, FLOORS and CEILINGS to reflect precious light back onto your plants. Growers also put it over top of plant containers, rockwool cubes and other grow medium to stop the growth of algae and reflect light up to their plants. Waterproof! Can be used to protect your floors and walls from spills, dirt, mold, mildew and stains. It reflects light and acts as a heavy duty tarp at the same time! An excellent alternative to MYLAR in that is SUPER REFLECTIVE and MORE DURABLE than MYLAR. Its thick Heavy Duty construction lends itself very well to cleaning and will not "smudge", "scratch" or "crinkle" like reflective Mylar tends to do. Please see our TARP ZIP UP that allows you to put a ZIPPER into the reflective fabric - it is really cool!THIS STUFF ROCKS!Better than Mylar! More Reflective than Black White Poly! Even has IR Blocking Qualities! This fabric is the PREMIER product for lining your grow room walls!It is opaque (does not let light through it) so it can also be used as room partitions, or for light-proofing or light-blocking!
