Common Questions: Windows in Longmont
Energy Star-rated double-pane windows with Low-E²/Low-E³ coatings and argon gas fill are the standard for Colorado, with U-factor below 0.30 and SHGC (solar heat gain coefficient) tuned to climate zone 5B. Triple-pane with krypton gas pushes U-factor below 0.20 for foothills and high-altitude homes. Look for ENERGY STAR Most Efficient certification, NFRC labels, and warm-edge spacers (not aluminum). Red Hawk installs Andersen, Pella, Marvin, and Milgard with Colorado-spec Low-E coatings tailored to each home's orientation.
Replacement windows in Colorado run $500–$1,200 per window installed for standard double-hung vinyl and fiberglass, $1,000–$2,200 for premium wood-clad and aluminum-clad, and $1,500–$3,500 for impact-rated or large-format custom sizes. Pricing includes window unit, install labor, interior trim restoration, exterior caulking, and disposal. A typical 2,000 sqft Colorado home has 12–18 windows, putting full-home replacement at $9,000–$25,000 for standard, $15,000–$45,000 for premium. Red Hawk provides itemized per-window pricing.
Andersen 100 Series (Fibrex composite frame), Pella Impervia (fiberglass), Marvin Elevate (fiberglass), and Milgard Tuscany are top Colorado choices for durability and hail resistance. Hail-rated glass options (laminated impact glass) are available across all these brands and survive 2-inch hail without breaking. Vinyl windows from major brands handle hail well in the panes but can crack at frame welds in extreme events. Red Hawk recommends fiberglass or composite frames for foothills exposure, vinyl for budget builds.
