DERPAL door is a real, traditional door made of natural pine or oak wood. For their production we use only natural raw materials obtained from Polish certified forests. The secret of the excellent quality and growing interest in our doors is the perfect combination of human work and modern technology. The most important aspect of our production is to have the appropriate facilities to process the purchased sawmill material. Wood from the first stage of production is sawn, seasoned and dried in a factory sawmill.
