Recommended: Double-pane Low-E with argon fill
Western Washington's mild, wet climate means moisture resistance is as important as thermal performance. Vinyl and fiberglass frames are preferred. Eastern Washington's colder, drier climate benefits from triple-pane. Puget Sound Energy and Seattle City Light offer rebates.
