Product▲	FrameThe frame material. Aluminum-clad wood has a timber frame with an aluminum skin outside; all-wood shows timber on both faces.	OperationHow the window opens: casement, awning, hung, sliding, tilt-turn or fixed. The symbols show the hinge side or travel direction.	RatingThe NAFS performance class and grade, e.g. CW-PG70. Shows the loads the window passed in testing.	DPThe wind load, in pounds per square foot, a window is rated to resist. Upper floors, corners and coastal sites need more.	U-factorHow fast heat passes through the whole window. Lower is better insulation. US values are in Btu/h·ft²·°F.	SHGCSolar heat gain coefficient: the share of the sun’s heat that gets through, from 0 to 1. Lower keeps homes cooler.	STCSound transmission class: how well the window blocks speech-range noise. Higher is quieter; 32 and up is noticeably quiet.	ImpactTested to withstand wind-borne debris (ASTM E1886/E1996). Required in hurricane debris regions unless shutters are used.	GlazingThe number of glass panes in the sealed unit: double, triple or quad. More panes insulate better and weigh more.	InstallHow the unit attaches to the opening: nail fin, flush fin, block frame or replacement insert.	Lead timeTypical weeks from a confirmed order to delivery. Custom wood and clad lines usually take longest.	Glass seal warrantyCoverage against the sealed glass unit losing its seal, which shows as fogging between the panes.	Verified
