[Technical Series] Insulating Doors & Windows 101 (Part 1): What the Thermal Numbers Actually Mean
Can thermal conductivity tell you how the whole window performs? And how should you read SC?
Energy-efficiency rules keep getting tougher, and doors and windows are still the weak link in the building envelope. Pick the wrong system and you feel it in both the energy bill and indoor comfort. Then the spec sheet hits: is a lower K value always better? Can thermal conductivity tell you how the whole window performs? And how should you read SC?
This guide starts with the physics: where the energy comes from, how heat moves, and which numbers actually matter when choosing a window system.
