You Chose the Glass Carefully, but the Whole Window Still Feels Different—The Problem Is the Part You Overlooked

You picked the perfect glass—but the frame can quietly undo all of it. Meet the part of the window nobody specs: the frame and its thermal bridge.

Chose great glass but the window still feels cold? The problem is the frame. Compare frame thermal conductivity, thermal bridging, and why whole-window U-value ≠ glass U-value. Includes the Passive House ≤ 0.8 W/(m²·K) benchmark.

Installed insulated glass, but it’s still hot in summer? It’s not a quality problem—it’s the type you chose

Insulated glass isn't one product—it's a whole family. Solar-control, Low-E and gas-filled units each block a different kind of heat. Pick the wrong member, and summer heat still walks right in.

Still hot in summer with insulated glass installed? It's not a quality problem—it's the type you chose. Compare solar-control, Low-E and gas-filled glass, plus warm-edge spacers, to match the right IGU to your climate and window orientation.

Installed insulated glass, but it’s still hot in summer? It’s not a quality problem—it’s the type you chose

You didn't buy a fake. You bought the wrong member of the family. Insulated glass comes in types—and summer heat only respects the right one.

Still hot in summer with insulated glass? It's not a quality problem—it's the type you chose. Learn the 3 types, 3 performance levels, and the warm-edge spacer detail that matter.

With the AC on, why is it still hot by the window? — The heat isn’t being blocked; you just can’t see where it’s getting in

Radiant heat passes straight through ordinary glass — invisible, silent, and working against your AC all day. See how vacuum glazing stops it at the window.

Why does the spot by the window stay hot even with the AC running? This article breaks down the science: heat enters through glass along two invisible paths—direct solar short-wave radiation and heat transfer driven by indoor-outdoor temperature differences. It explains the three metrics that actually decide window performance (U-value, SC/g-value and LSG), compares four...
