<p class=MsoNormal><font size=2 color=navy face=Arial><span style='font-size:
10.0pt;font-family:Arial;color:navy'>I used a nano based paint about 10 years
ago. Not for insulation, didn’t hear about that?? but because it works
incredibly well as a paint filler. Exterior paint for houses is a problem. It
is a sacrificial surface that has to be renewed 5 years on average and over its
history has presented a lot of long term toxicity problems (heavy metals
primarily but also anti-fungals, etc.) for the soils surrounding houses. Paint
deteriorates primarily because of breaks in the paint film. Traditional fillers
have been low cost materials such as simple chalk. These particles are coarse
with numerous edges that capture dirt and basically break the film down. Nano
particles are spherical and as part of a film provide extreme resistance to retaining
dirt and subsequent weathering and mildew.<o:p></o:p></span></font></p>

<p class=MsoNormal><font size=2 color=navy face=Arial><span style='font-size:
10.0pt;font-family:Arial;color:navy'>The renovation projects that it was used
on have held up extremely well. After 10 years there is no evidence of failure
(peeling, blistering, fading). The paint had no anti-fungals but the walls show
no mildew problems (which is common here). It was a pretty impressive product
and the painters loved working with it and it required less paint. Obviously
the surfaces have weathered and the eroded material is now part of the atmosphere
and soils and I think that though it may not pose significant risk it is adding
to the pot and increasing the risk. In comparison to ‘normal’ paint
(whatever that is now) it means that we use less paint (less often) and
decrease that waste. How it compares in the end is anyones guess.<o:p></o:p></span></font></p>

<p class=MsoNormal><font size=2 color=navy face=Arial><span style='font-size:
10.0pt;font-family:Arial;color:navy'>A goal in greenbuilding is to minimize
toxicity to the environment and the maintenance and renewal of exposed surfaces
has a high cost. The first line of defense is design solutions and the second
is selection of appropriate ‘low risk’ materials. Solutions such as
earthen wall finishes and soil covered roofs I think are very appropriate
finishes to expose to the environment but not quite the acceptable norm at this
point.<o:p></o:p></span></font></p>

invariably none of them were any more effective at insulating than a<br>
clay-based paint. I have no experience with this particular product,<br>

hope I'm wrong about one of these products eventually though, as<br>
paint-on insulation would be very beneficial!<br>

The closest I've seen to a thin insulation that have proven results<br>
