When selecting wallcoverings, understanding the specifications is crucial for making the right choice. Key specifications include material type, such as vinyl, fabric, or paper, which determines durability and application suitability. The backing type, either woven or non-woven, affects ease of installation and removal. Measurements like width and length per roll influence the amount needed for a project. Other important factors include pattern repeat size, which impacts design continuity, and the wallcovering's washability, scrubability, and resistance to fading. Fire ratings and VOC emissions are also critical for ensuring safety and environmental compliance.
