2022年8月17日 — An R-value measures thermal resistance, indicating insulation performance. U-values measure thermal conductivity and are used to calculate ...
R-Value: A measurement of the resistance of heat transfer through the glass. The higher the R-Value, the better the window insulates against heat. Solar ...
2023年7月20日 — That's where the R-value comes in - it measures the thermal resistance and insulating properties of windows. Essentially, windows with higher R- ...
2021年1月3日 — The U-value measures heat transfer (loss or gain) through the actual glass. U-value does not rate the specific material like the R-value does.
When paired with single-pane windows, Indow inserts can improve the R-value to 1.87, or 94% of a double-pane window! With a double-pane window, the R-value will ...
2023年3月1日 — Using the photo of the Alpen window sticker as an example, R-value = 1/0.16, or R-6.25. That's a really good R-value for a window. Performing ...
