January in Kansas is often a cold month so we tend to think about lined draperies as a source of warmth. I guess that is why we always have our free lining special in January every year. You can select the fabric of your choice and the lining we add to the fabric will be free.
Why do we line draperies?
Adding lining to your fabric of choice will add another layer of insulation and “dead air space” just as if you were wearing a jacket or coat. Even though we now have windows that are more insulating, a window has an R factor much below the R factor of your wall, so additional insulation is always good for decreasing your heating bill and for added comfort.
Why do we interline draperies?
Interlining adds the layers to our windows like we add layers to our body. We put on a shirt, a sweater and maybe even a coat to add warmth to our bodies on cold days. Interlining draperies adds an additional layer of felt to your drapery lining and your drapery fabric. Interlining can also be used to give fabric more bulk and hand. We often use this method with silks or silk-like fabrics to give the silk, which is very thin, more body.
Of course you can add lining and interlining to roman shades too. And many shades on the market have additional insulating qualities such at Duette® shades from Hunter Douglas. Hunter Douglas’ standard honeycomb shade has a cell within a cell so there are multiple layers of insulation. That insulated space allows the cold air to warm slowly before it gets into the room and keeps you comfortable.
Does room darkening lining help with insulation?
Of course room darkening lining reduces the light in the room but it also is an excellent insulator. In fact, it is often more energy efficient than regular insulated lining. So if you want a darkened room for sleeping, you will get the added bonus of extra energy efficiency as well.
