what kind of housing insulation? and how do you set it up? got any pics of that?

My house is never really really cold, but it's always going to be colder than my BP's need. and it's even worst this past two weeks because of family from alaska being in town and being too hot all the time. if I didn't lower my temps in the house, they would have sufficated. Right now I have fleece blankets wrapped around the tanks to keep their temps up. I was looking at getting a second set of UTH's to put on the cold side on lower temps than the hot so that it keeps both sides at the right temp.
