Zone 9 heat, afternoon west sun, and ranch homes that earn back the fiberglass premium in year 12 when the vinyl across the street is warping. Quote in 48 hours.
Sherman Oaks is where the vinyl-vs-fiberglass decision is most consequential in our service area. It's zone 9, most ranches face south or west, and the Valley afternoon heat load is the highest of any residential area we serve. Vinyl windows installed on a Sherman Oaks west elevation in 2010 are today showing visible warp on the frame and sash gap issues. Fiberglass won't warp under zone 9 conditions in 40 years of direct sun. The cost premium — $400–$700/window over vinyl — recovers at the 12-year mark in energy savings and warranty costs avoided.
Marvin Elevate or Pella Impervia fiberglass. For Sherman Oaks homes with a traditional or transitional aesthetic: Andersen 400 Series with fiberglass-clad exterior (compromise between wood-look and thermal stability).

Permitting in Sherman Oaks is straightforward for this type of work — no unusual regulatory overlays.
