Hi -- I'm the bubble wrap guy from BuildItSolar.

We actually use the bubble wrap on windows that don't have a view. The bubble wrap still lets in plenty of light.

We have managed to find some kind of strategy for insulating or storm windows on just about every window in the house -- some of them were very difficult to work out due their odd shape.

The triple wall polycarbonate inside storms work particularly well.

I did a heat loss for our house, and after beefing up the attic and crawl space insulation, windows were about 50% of our total heat loss. Getting some kind of insulation or inside storm window on every window really helps. Our heat bills are less than half what they used to be:

Very nice website -- thanks for your work.

I doubt this is any better than a plastic sheet window insulation kit, since one layer of the bubble wrap is in contact with the window there is no insulating air-gap between the window and the bubble wrap.

Taping a plastic sheet around a window creates a large insulating air gap that also includes the non-glass parts of the window which also conduct heat, as well as further helping seal the window against minute drafts. I think that plastic sheeting made for this purpose has some degree of IR reflectivity to improve it's insulation value as well - it feels warm like a space blanket. Not to mention it's clear and relatively unobtrusive.
