Why Choose Pella
  • Assembly-line testing-Only Pella factory-tests every venting ProLine window for air infiltration to ensure it meets or exceeds industry standards. If it doesn't pass, it doesn't ship! Most other manufacturers only do random testing.
  • State-of-the-art testing laboratory-One of the best in the industry. Pella continually tests every component of Pella Windows & Doors under the harshest conditions-the burning rays of the sun, salt air, acid rain, excessive humidity, extreme hot and cold temperatures, high wind and driving rain to assure that Pella products will perform the way Pella says they will, day after day.
  • World-class manufacturing-Pella's manufacturing processes are continually evolving and improving so that they can continue deliver the highest quality and latest innovations to customers.
  • Factory assembly-Pella uses factory-controlled processes to manufacture over 50 different combinations of windows and entry doors that are immediately ready to install. Many other manufacturers' products require assembly at the job site, which could result in questionable quality.
