Kolm,
Wow, lots to reply to this time. Good post, again.
1) My assertion was that this product works (and only that). However, you "think" it would be expensive even in special cases... yet, you aren't detailing the cost of applying dual-benefit solutions. I think we can debate this one all day, because it depends on which properties are appealing to the user. In some cases, Nansulate may not be worth the money. In other cases, it'll be cheaper. You'll see below, my reasoning, in some of the other responses.
2) No problem about declining the offer.
3) Agreed, it may be effective but not "efficient". But again, that depends on which properties are of value to the user. When dual properties are desired, or no other good solutions are available, it may be less expensive. It all depends. But I don't really disagree. Those items are debateable and particular to each application.
4) Moving to a better insulated home would be WAY more expensive than spending say $2000 on Nansulate. Realtor fees, closing costs, furnishings, etc, etc. C'mon, I hope you were just joking in that comment. Not to mention, a person may not want to leave their home if all it takes is $2 or $3000 spent on insulating paintable coating versus selling their house (haha! It's funny to even comment on that!). I like your creativity, though! All your ideas are good, but I don't think the best ideas in every case.
5) Painting the roof white would help some, via reflection, but paint doesn't insulate well so it wouldn't help nearly as much. Check the K value for a "paint" (nansulate is not a paint, but is a resin based polymer) - I assure you a paint doesn't have a K value of .017. Not to mention, if the roof shows from the street (many do, and mine does) it would be obnoxious looking to the neighbors and then would look very ugly as it got dirty. Want to scrub the roof every year also?
6) There is no space in between my roof and wood beam ceiling. And, removing part of the roof, alternatively, would take a lot of manpower and could mean it ends up being more expensive - as well as allowing oppty for mistakes in putting it back together again. But in my case, there's no space anyway so it doesn't matter.
7) Yes, I agree, it may be seen as having "extra" money to spend on "looks". When regular insulation can't be used, looks very well may be important to the owner (that's a fact - but I know, not in every case). But since it will insulate additionally, no matter what else you've already used as insulation, it is an investment which ends up paying for itself. So, it's not just money spent... but it's money invested. Still, it's not needed in every home (nobody is claiming that). It would help every home, but an already highly insulated home might not benefit quite enough to make the owner feel smart in purchasing Nansulate. We agree on that. However, I DO maintain that it may be a quicker and less expensive (let's say .50+/sqft) solution than tearing up a home to put in more insulation. It depends on the home, period. Manpower, materials, reconstruction, etc, all are factors. Important factors. Not everyone can do it themselves via free manpower.
8 ) 4cm of foam outside, then repaint? C'mon, that is also a bit overboard. Plastic foam cost, installation crew cost, then paint materials cost, and painter labor cost? Two works crews? Changing the look of the house if the plastic foam can't be applied everywhere or would cover up important materials, wires, fixtures, etc? Nansulate would likely be MUCH less expensive. We could probably detail this together if you wish, and you'll see. All Nansulate takes is one crew (a painter) to mix, apply (can even spray on), and then the job is done. With similar insulating results. I get your point, though, and don't completely disagree on this item.
9) Metal roof... I agree; not all that common or needed. But you never know, a person might end up determining that the metal roof is conducting too much heat. In fact, ironically... my mother has a metal roof on her older cottage type of home which she lives in, and I want to apply Nansulate but she keeps threatening to move (for other reasons), so I don't want to waste the $$ only to see someone else move in until I know if she's staying. About corrosion application plus regular insulation... you're again assuming free manpower. For some folks, this would mean two work crews and two products which might be more expensive. Not everyone can do it theirself - a great many people cannot, or don't want to.
10) Mold... ditto, I don't know a lot about it. Mainly, Nansulate prevents its growth but I don't know the ins and outs of existing mold. I see the mold issue as a side-item. By the way, Nansulate has also been officially tested to 100% effectiveness of lead encapsulation. Other paints don't (but it's not really a "paint", as you know).
11) I agree, it's potentially sensible. And in some cases it's not. Personally, I still think it's most effective in industry, but I'm increasingly intrigued by the home testimonials. I really like the textile testimonial in which they said they spent $40,000 on Nansulate, but now save $100,000 per year via lower energy consumption. That is a heavy-hitting solution. Forgive me if I have the figures wrong, but I think I recall correctly on that. Didn't feel like looking right now.
Thanks for the discussion. You're making good points, and you seem to have looked at the info I provided... and are receptive to possibilities. And in return, I of course know that this product is not magic. It's simply an additional option which didn't previously exist, and which works a lot more effectively than most people think it could/should, and it may be best suited to certain conditions or scenarios (not all scenarios, we agree).
