The Prido folding door is a strong choice for industrial environments thanks to the market’s lowest service requirements, a 7-year warranty, and manufacturing in Sweden since 1973. The door’s sandwich construction provides an approximately 40% better U-value than frame-built folding doors. Prido sells 13,500 doors annually and, through high volume and efficient manufacturing, has been able to combine high quality with a lower total cost over the door’s 25-year service life.
