Retractable awnings are great because they can make your house and porch cooler in the summer time. They can make your house worth more in value.
Putting new windows in the home will not make the house more energy efficient. There would have to be a specific type of glass in the window.
you can make one, with ping pong balls and aluminium foil
Aluminum foil can be used:to wrap foodto make a radar reflectorto prevent aliens from reading your mindto conduct electricity in narrow areasas an insulating layerto reflect heatto make a capacitorin chemical experiments to make hydrogento block off windows in grow ops
A decent company for installing replacement windows is The Home Depot. They will make a window that is customized fit for your house, and go to your house to install it.
You can open the windows in your house and use fans. Or you can have you air repaired.
ummm...Yeah....With foil
Hardwood floors are cooler to the touch than carpet, but I don't consider them to be a cold flooring, nor do they make a house cold. The house is cold because of the way it is built and insulated.
the moisture from your breath condenses on the cooler windows make sure you have the ventilation control set to outside air not recirculated air
You can make guitars out of aluminum foil in any way that you'd like. You can for example cut out a guitar shape in the foil and drawstrings on it with a marker.
