Types, Frames & Glass
The compare / by-type cluster: double-hung vs casement vs sliding vs awning vs picture, vinyl vs wood vs fiberglass vs aluminum vs composite (cost & lifespan), single vs double vs triple pane (U-factor), bay vs bow cost, a low-E / argon-krypton gas-fill reference, and a generic good/better/best tier reference (no live prices). Cost compares use your own prices; U-factor and tier values are labeled typicals.
Planning estimate: this is a planning estimate from the numbers you enter — not a bid or a contract. Window and door pricing depends on size, type, frame material, glass package, full-frame vs insert, trim, disposal, height/access and local labor. Get itemized written quotes from licensed, insured window/door installers before you commit.
Typical published planning values / code minimums — NOT a certified design or a compliance sign-off. Actual egress compliance and energy performance depend on your local building code (AHJ), climate zone, the exact product’s NFRC-rated U-factor & SHGC and the installation; confirm against local code and the manufacturer’s NFRC label, and consult a pro. Structural headers for enlarged openings, whole-building heat-load / HVAC sizing and code certification are set by code and a professional — not engineered here.
