Surface finish durability

Doors that resist scratches, bumps and stains

Door surfaces face diverse and daunting challenges on a daily basis – staining substances, aggressive cleaning agents, impacts from objects, scratches, adhesives and more.

As one of the earliest members of the German RAL Quality Assurance Association for Interior Doors, neuform offers planners and architects long-lasting products with exceptionally durable surface finishes. In addition to smart design, finishes play a central role in the longevity of our solutions. By extending our quality and testing criteria to including surface finish durability, we are setting new standards in excellent, highly resistant doors – and underscoring our dedication to going the extra mile.
