SoffitFlow's exceptional durability begins in construction. Each unit is precision-engineered using injection-molded High-density Polyethylene (HDPE), a material known for its strength and resilience. This robust polymer formulation allows SoffitFlow to withstand extreme temperature fluctuations — ranging from -40˚F to 150˚F — without compromising performance or structural integrity. Unlike traditional plastics, HDPE has a significantly higher heat absorption threshold, which helps prevent warping of the damper door, ensuring it continues to operate smoothly, maintaining optimal airflow.
SoffitFlow's remarkable low moisture absorption rate makes it particularly well-suited for humid or coastal environments, where damp conditions often degrade standard venting materials.
HDPE's impressive list of benefits doesn't end there:
- Lightweight, yet incredibly tough
- Resistant to weathering
- Superior thermal stability
- Unaffected by long term UV exposure
- Excellent moisture barrier properties
In addition to its technical advantages, all SoffitFlow units are proudly made in the USA! You can trust in the quality, engineering and reliability of a product built to meet the highest manufacturing standards.
