What the climate around St. George means for windows

For homes around St. George, heating and cooling both matter: compare U-factor and solar heat gain together on the NFRC label rather than optimizing one side of the year. The station's annual mean temperature is near 63°F with about 9 inches of precipitation, so flashing and water management around the opening deserve the same written attention as the glass package.

Climate figures are NOAA 1991-2020 normals recorded at ST GEORGE, UT US (near St. George); they describe the recording station's location, not any specific property.

Comparing window performance the measurable way

Utah's ENERGY STAR Version 7.0 zone criteria (Northern: U-factor ≤ 0.22, SHGC ≥ 0.17; South-Central: U-factor ≤ 0.28, SHGC ≤ 0.23) set the qualifying levels; the county's zone determines which applies to a St. George home. Whole-product NFRC ratings on the exact quoted window are the comparable basis, and no rating supports a guaranteed savings figure for an individual home.

Openings, scope, and what belongs in writing

Before comparing double-pane replacement proposals in St. George, document the openings themselves: full unit versus glass-only scope; glass construction and coatings. Homes built before 1978 add a federal consideration: work that disturbs painted surfaces falls under the Renovation, Repair and Painting rule, so confirm the construction year and ask how containment will be handled.
