This core is characterized by high stiffness and compressive strength, which is why it is perfect for the joinery industry. The door core made of PUR foam is also very popular. The closed-cell structure of the PUR core allows for maintaining thermal, fire and mechanical stability in all environmental conditions for years of operation. PUR foam is resistant to weather conditions (rain, snow, wind) and its next advantage is the anti-moisture effect. The core has very good thermal properties and is resistant to mold and other fungi throughout its service life.
