Q:

Q: What is R-value on cellular shades?


A:
R-value indicates a material’s resistance to heat flow. Higher R-values mean better insulation. With cellular (honeycomb) shades, the air pockets slow heat transfer, improving comfort in both winter and summer.

Q: How do single-cell and double-cell shades differ in R-value?


A: Double-cell shades typically provide higher R-values than single-cell because there are more air chambers. Deep pleats and tighter weaves also help increase thermal resistance.

Q: Do light-filtering vs. blackout fabrics change the R-value?


A: Yes. Blackout fabrics usually add mass and layers, boosting R-value compared to light-filtering fabrics. If insulation is your priority, choose double-cell with blackout fabric.

Q: Why do published R-values vary between brands?


A: Test methods, shade size, fabric composition, liners, and even mounting style can change results. Use R-value as a comparison within a brand or product family, and consider overall build and fit.

Q: R-value vs. U-factor—what’s the difference?


A: U-factor measures how quickly heat flows through a product (lower is better). R-value is the inverse (higher is better). Some manufacturers list one or the other; both describe insulation.

Q: Inside mount or outside mount—does fit affect insulation?


A: Yes. Reducing edge gaps improves performance. An outside (overlap) mount that extends past the frame helps block drafts. For inside mounts, add side returns or layer with drapery.

Q: What R-value should I aim for in my climate?

  • Cold climates: Double-cell + blackout for the highest R-value.

  • Mixed climates: Double-cell light-filtering balances light and insulation.

  • Hot/sunny climates: Light-colored cellular fabrics reduce heat gain; consider blackout on west/south windows.


Q: Can installation upgrades improve effective R-value?


A: Add side channels, top valances, or layer with lined drapery to cut convection around the shade and boost real-world performance.
