In October 2019, a class-action lawsuit
was filed against Allura USA, Plycem USA, and Elementia USA for allegedly falsely advertising that fiber cement siding – including Plycem/Allura cedar siding – is durable, engineered to endure harsh weather and high wind climates, and guaranteed for 50 years when, according to plaintiffs, the siding starts to crack and deteriorate after only a few years.

, Case No. 19-cv-1226, N. D. NY.)
