Blocking heat from windows

[Not Afraid]

I'm in the process (well, Milt is) of repairing our disintegrating French Doors in our bedroom. Milt works on vintage houses and will be injecting a resin into the doors to repair the wood rot, stripping the paint, getting the windows that are in the doors to open and generally making the doors as "new". They will still have to be painted and not varnished.

The next thing he is going to do is to put in restored double hung windows to replace the 50's slat windows in the bedroom. Then I can have air conditioning in the bedroom!

Our Living Room is still hot in the afternoons, but with the windows open, it's not bad at all. I'm looking into the film to put over the big arched LR window as a heat-reflecting option - IF it won't look strange or ruin the look of the house.
