I have a 20 year old, white colored, two story house that's never been painted. During the summer months it get to be about 80 degrees outside and feels about 90 or so inside without air conditioning (I only have a portable unit). Basically it's unbearable for me anyways.
The thing is it feels just as hot downstairs as upstairs, so I'm thinking a good portion of the heat is coming from the heat hitting the walls. Is there any kind of paint that will deflect heat that I can use to repaint my home?
And could someone make a complete list of all things I can do to lower the internal temperature of my house during the summer? It's very important that I get this done for the sake of the elderly residents on the property.
