Picture Windows

Angled exterior view of a black picture window, rendered from the Panes 3D configurator

A picture window is fixed glass for daylight and views. It does not open for ventilation or emergency escape; plan those needs separately.

Best uses

Living rooms with scenic views
Dining areas and great rooms
Above furniture where operation isn't needed
Combined with casement or awning windows
Modern and minimalist designs
High walls and vaulted ceilings

Maximum Natural Light

Large, unobstructed glass area floods your room with beautiful natural light, making smaller spaces feel more open and expansive.

Unobstructed Views

A fixed glass section has no operating sash or meeting rail. Frame edges and optional grilles still affect the view.

Compare Certified Ratings

Compare whole-product U-factor, SHGC and air-leakage ratings for the selected glass, frame and size. The operating style does not establish certification or energy savings.

U-factor: Heat transfer through the complete window. Lower values indicate better insulation. U.S. values use Btu/(h·ft²·°F); metric equivalents use W/(m²·K).
SHGC: Solar heat gain coefficient, from 0 to 1. Lower values admit less solar heat.
VT: Visible transmittance, from 0 to 1. Higher values admit more visible light.

These reference configurations have no grilles. Each row preserves the NFRC manufacturer code for its frame, glass and gas combination. Select the matching series and glass package, and confirm the CPD number and label for your order. Different glass, grilles, frame systems and joined assemblies can have different ratings.

For Midwest and Northeast projects, compare heat transfer, winter sunlight and summer exposure together. A lower U-factor indicates less heat transfer. A lower SHGC admits less solar heat; a higher SHGC admits more. VT describes visible light transmission. Orientation, shading and local code affect the choice. NFRC ratings alone do not establish ENERGY STAR eligibility.
