Does any one know anything about the new paint on insulation. I believe it is called nansolate. The claim is that 3 coats will help a lot on cinder block walls.

Our house was built in 1963, at that time gas was cheap and no one thought much about it. Now that has changed and we are wondering what to do. Does anyone have any infomation to share. We live in central Colorado and it gets quite cold.

Thanks you

I have been in the building industry for 35 years and have seen thousands of claims from every trade professing fantastic energy savings by using just about anything from paints to duct cleaning. And while some tiny gain may be achievable, very few are worth the expense or effort. Most are, as I described, fantasy. While some calculatable improvements could be claimed, I am confident in saying that there is NO paint that will provide you with a NOTICABLE improvement in your energy costs.

If you want to improve your energy consumption, first look to the ceiling. Install insulation that will give you a R-19 (moderate climes) to R-40 (extreme climes) total value. Seal all cracks and move any attic access out of the conditioned space.

Next, the walls. Seal all windows and doors. Add insulation. In your case an effective upgrade would be to cover the interior surace of the walls with 1 inch urethane insulation board and then drywall. This also creates work extending electric boxes and trimming to door frames. This is a lot of work but it will provide improvement that you can actually notice. Also, look hard at your windows. Homes built in the sixties have some of the worst windows (energy wise) ever produced. You can replace them with double pane units or overlay with storm windows.

If you have a clothes drier in the house, move it to the garage or provide make-up air to the laundry room so it isn't sucking 400 cfm of conditioned air out of the house.

Next, move your air conditioner/heater out of the attic and into the conditioned space. Placing AC units or the ductwork in the attic is archaic an extremely wasteful of energy.

While you may not be able to do all of these things, any one of them will provide savings vastly greater than the paint-on-insulation. For more reliable advice, find a reputable GENERAL CONTRACTOR who does not have a vested interest in any one product.

You will get expert comments, but no first hand experience. Nansulate is in use. From application to heat exchanger pipes, quartz home electric heaters, to dirt bike muffler shields, to keep the hotpants set from burning their legs.
I had a difficult time trusting it, but I have touched where I should have been burned and it was barely warm.
