In which situation is double-stripping typically not used?

Double-stripping is a technique employed in carpet installation primarily to provide added durability and stability in areas subject to heavy use. It involves layering the carpet over two separate strips, which can help in managing the stress that high-traffic areas exert on floor coverings.

In the context of staircases, double-stripping is typically not practiced because staircases require a different installation approach due to their unique characteristics and the necessity for safety and aesthetic considerations. The use of a single strip allows for a cleaner finish, minimizes bulk, and reduces the risk of slips or trips that can be exacerbated by additional thickness from double-stripping. Furthermore, stairs often benefit from a snug fit and can be more effectively secured with a single strip, ensuring the carpet adheres properly without compromising the safe transitions at the edges.

In contrast, heavy foot traffic areas, residential installations, and light commercial spaces often benefit from the increased resilience provided by double-stripping, making it a common practice in those scenarios.
