The best advice would be to take a look at a sample of glass and judge for yourself before you purchase the window. Look through the glass outside, not through the showroom window. Hold the glass at various angles. If your provider says they can’ t show you a sample of glass, you’re shopping at the incorrect dealer.
Producers have long used the term shading coefficient (SC) to explain how much solar heat is transmitted by every one of the glazing systems. An entirely opaque unit scores 0 and one pane of glass scores 1 on this relative scale. A transparent double-pane window scores 0.84 because is allows 84 percent as much heat to pass as one pane of glass. SHGC is the fraction of accessible incident solar heat that goes through a window unit. The key distinction is that SHGC looks at a proportion of available solar heat as opposed to looking at a fraction of what comes through a single pane of glass. Because of this it’s about 15% lower compared to SC values.
Glass coatings are formulated to select certain wavelengths of energy. It’s likely to have a glass coating which blocks long-wave heat energy (non SHGC) while allowing generous levels of shorter wave light energy (large VT) to enter a house. A low SHGC will decrease air conditioning bills more than if you raised the insulative value of your window with an extra pane of glass. SHGC under 0.40 is advised for hot climates. In cold climates you need both high visibility and high solar heat gain. In swing climates such as Washington D.C., picking a SHGC involving 0.40 — 0.55 is reasonable since there’s a trade-off between heating and cooling loads.
