What are the best window types for energy efficiency in Western Washington?
We normally recommend fiberglass or vinyl windows with double- or triple-pane glass for homes in Western Washington. These types offer exceptional insulation for cold and damp weather, which is very common in Lake Forest Park.
Windows with low-E coatings and argon gas fills can help with heat transfer and moisture buildup so your home stays comfortable year-round. If you need a better view or more natural light, we’ll likely suggest casement or picture windows.
