Company Performance Metrics
Rasper manufactures custom wooden windows, doors, stairs, and architectural wood details for both historical and modern buildings. The company focuses on heritage conservation and designs solutions for environmentally valuable areas and protected architectural monuments. It produces replicas of historical doors and windows from existing fragments,
keeping traditional aesthetics while aligning with contemporary thermal and construction standards. Rasper serves corporate and private clients with individually tailored projects. Its offering includes custom wooden windows in several opening types, internal and external doors made from drawings or historical copies, and custom-built stairs primarily using hardwoods such as ash and oak. The company also manufactures additional construction details such as hatches, cornices, paneling, and interior trim, using traditional techniques including hand-painting with linseed oil paints and fitting period-appropriate hardware when required.
