These are my second favorite window treatments, right after the dual roller shades. They offer a very neat and relaxed feel to the room they get installed to, and there is a style for every person out there!
They do a great job on increasing the energy efficiency of the room they installed in. Air pockets that are created in the construction of the shades offer great insulation and increases the energy efficiency of you house/office. You can also get double cells to increase even more your home's energy efficiency.
Honeycomb shades can also be a great light-filtering shade, so if you are trying to reduce the outside light (maybe trying to get more sleep time) they are a great option. You can even go for a blackout fabric to block all light from coming into to room.
You can also add convenient lift options like cordless, top down-bottom up , and motorized remote control.
The brands that I use and I am well familiarized with are Hunter Douglas, Timber Blinds and The Window Outfitters; I also know other brands like Norman, and a few others, and if there's another brand that makes you curious, let me know of them and we'll take a look together. I'm sure I can offer you the best deals for your house transformation.
