The A-Series is what Andersen builds when the brief is “no compromises”. Its own description of it is short and worth quoting: “Choose from a variety of beautiful and durable interior wood species, with fiberglass and composite exteriors that won’t peel, blister, fade or corrode.”
That is two different materials doing two different jobs, and the split is the whole design. Wood is what you want to see and touch. Fiberglass is what you want facing a January in New Jersey.
Not a wood-look finish — timber, in a range of species, ready to stain or paint to match the floors, doors and joinery already in the room. In a pre-war house that is the difference you notice from across the room, and no composite reproduces it.
This is the part that matters through a freeze-and-thaw winter. Every frame expands in heat and contracts in cold; the question is how much, and what that does to the seal around the glass. Fiberglass moves very little with temperature — close to the rate glass itself moves — so the frame and the sealed unit inside it stay roughly in step instead of working against each other.
The other half of the same idea. Timber barely responds to temperature at all; what moves timber is moisture. So the wood lives indoors in conditioned air, and the fiberglass and composite exterior keeps the weather off it entirely. Each material is doing the job it is actually good at.
Andersen’s claim for the exterior is that it “won’t peel, blister, fade or corrode”. Their Stormwatch® specification takes the same idea to the coast, where salt air ends most window finishes early. Inside, the wood is yours to finish once and leave.
