The wallpaper that is generally cheaper for wall covering is non-woven wallpaper. Non-woven wallpaper is made from a blend of natural and synthetic fibers, which makes it more affordable compared to traditional paper wallpaper. According to a report by Grand View Research, the non-woven wallpaper market is expected to grow at a CAGR of 5.1% from 2021 to 2028, driven by its cost-effectiveness and ease of installation.

Non-woven wallpaper is cheaper due to several factors. Firstly, the production process for non-woven wallpaper is more efficient and requires fewer materials, which reduces manufacturing costs. Secondly, non-woven wallpaper is more durable and can be washed, which means it has a longer lifespan and may not need to be replaced as frequently as traditional paper wallpaper. This longevity can offset the initial lower cost, making it a cost-effective choice in the long run.

Additionally, non-woven wallpaper is easier to install, which can save on labor costs. Traditional paper wallpaper often requires priming and wallpaper paste, while non-woven wallpaper can be installed directly over most clean, dry walls. This simplicity can make the installation process quicker and less expensive.

Data from the National Association of the Remodeling Industry (NARI) indicates that the average cost of wallpaper installation is $2 to $5 per square foot, depending on the complexity of the job. Non-woven wallpaper, due to its ease of installation, can potentially reduce these costs. Furthermore, the cost of non-woven wallpaper itself is generally lower than that of traditional paper wallpaper, with prices ranging from $1 to $3 per square foot, according to HomeAdvisor.

In conclusion, non-woven wallpaper is the cheaper option for wall covering due to its lower production costs, durability, ease of installation, and potential for reducing labor costs. These factors make it a cost-effective choice for homeowners and contractors alike.
