Jennifer writes from Saginaw, Michigan: "We're doing a research project for FIRST Lego League and we need to know what type of insulation to recommend to our local fire department who doesn't have any insulation on their roof or ceiling. What would you recommend?"

Answer: We recommend PINK insulation (because Owens Corning has a trademark on the color PINK when used with building insulation and is therefore the only company that can make and market PINK insulation). To go beyond that and be seriously helpful, we need to know more about the building you plan to insulate. Does it have a flat or pitched roof? Is there an attic you can access? Anything you can tell me about the fire department building will let me be more helpful in my answer.
