Choosing replacement windows requires finding the right balance between architectural style, thermal insulation, structural strength, and project budget. Pella simplifies this choice by offering distinct series engineered around three primary frame materials: vinyl, fiberglass, and wood/clad-wood.
If you are looking for a quick summary of the differences: Pella windows scale across budget vinyl (Encompass & 250 Series), heavy-duty fiberglass (Impervia), flexible wood-clad (Lifestyle), and luxury historic/contemporary wood (Reserve Series).
