Although energy-efficient glass makes a major difference in your comfort and energy use, quality construction completes the package.
State-of-the-art testing laboratory
In our state-of-the-art product-testing facilities, we continually test the components of Pella 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. And Pella tests for air and water infiltration and structural strength during the manufacturing process. These stringent measures ensure our windows and patio doors will perform the way we say they will.
Continuous improvement methodology
Continuous improvement is deeply ingrained in Pella's culture. Pella team members are encouraged to refine our processes so we can produce great results – the highest quality, most energy-efficient products and the latest innovations for our customers.
All Pella windows and doors – and a large selection of door combinations – are completely assembled in our factory – with no parts or pieces to put together at the job site. This helps ensure a weathertight seal and leaves little room for error when it comes to meeting Pella's high quality standards for performance of our products.
