Wood Types Pella ProLine 450 Series Double-Hung Window

Available with Pine interiors and low-maintenance aluminum-clad exteriors. All wood types are treated with Pella's EnduraGuard® wood protection for beauty and performance ... year after year.

EnduraGuard wood protection offers advanced protection against the effects of moisture. Here's the difference:

  • Pella's EnduraGuard® protection formula has three active ingredients to provide advanced protection against the effects of moisture, decay, stains from mold and mildew. Plus an additional ingredient adds protection against termite damage.
  • EnduraGuard wood protection has a greater concentration of protective ingredients compared to major competitors using immersion treatments.1

1Based on the average measurement of retained active anti-fungal ingredients and performance solids (Borates and Trialkyl Nitrogen Oxides) on sashes and frames of major competitors using immersion treatment.
