Westech Quality

Quality Control

Consumers may not be aware of the level of quality protocol necessary in our industry nor are they always knowledgeable of the standards by which manufacturing processes are examined. Westech Quality Assurance Protocol’s quality control staff is constantly on the job from raw materials through extrusion and finished product inventory. PVC resin is checked for moisture, color and bulk density. The compound batches are analyzed in computerized rheology machines for fusion and torque. Extruded profile samples are cut and checked “on line” for color, gloss and dimension then tested “off line” for impact resistance, as well as dimensional stability. UV resistance is checked through an accelerated weathering technique.

Westech designs Window and Door Profiles that are tested to meet AAMA, NFRC and CSA standards. Westech’s Product Development Group goes beyond safety codes to establish new benchmarks for the industry.

Look to Westech’s in-house testing and Quality Assurance protocol—when you demand the best, you demand Westech.
