Hello,

I need to buy some new window shades or blinds for my bedroom. I'm
considering cellular and faux wood. All the web sites claim that the
cellular shades insulate much better than regular type blinds.

Does anyone have any real experience with the cellular shades or knowledge
of them? Thanks,

Jason

We have the cellular shades on all of our windows, in Phoenix.
I haven't run any numbers-based experiments, but when the shades are
down in the daytime, the inside glass is very warm. At the same time,
the (one or two) windows where the shades are partly up have glass
that is much? cooler. This indicates that there is some heat going to
the room (or coolth going to the window, take your pick). So they do
something but I can't say how much.
In our case, the shades are in the window casement, not out beyond the
plane of the wall.
When I installed them, I made them fit reasonably snugly against the
window casement sides. This helped reduce drafts.
One thing I would do differently: I installed them close to the
glass. Next time, I would install them further away, so that the
latch doesn't interfere with the raising/lowering of the shades.
