Does artificial grass expand?

Like anything else, artificial grass will expand and contract when temperature changes from cold to hot or vs, this is the law of physics. However, we do have solutions for that. When we manufacture our artificial turf products, we use two solid layer of primary backing materials which dramatically increase the stabilities of our products. At the installation stage, we require installers to anchor all the edges of the artificial lawn by using 5-7" nails, proper stretch out the grass during the installation, and put average of 2 lbs of infills per sq ft. Combinations of having products made with best stability and manufacturer required installation procedures will significantly minimize the expansions or contraction issues.
