What the climate around Butte means for windows

For homes around Butte, heating dominates: prioritize a low U-factor and tight air leakage on the NFRC label, because limiting winter heat loss is where window performance pays off here. The station's annual mean temperature is near 40°F with about 13 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 BUTTE BERT MOONEY AP, MT US (near Butte); they describe the recording station's location, not any specific property.

Comparing window performance the measurable way

Montana's ENERGY STAR Version 7.0 zone criteria (Northern: U-factor ≤ 0.22, SHGC ≥ 0.17) set the qualifying levels; the county's zone determines which applies to a Butte 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.

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.
