Question
Hello: What is your take on Thermasave's product,stressed skin/foam core panels? I live in an older stick home which is giving me endless headaches,like sagging rafters,cracked foundation,etc.
These foam core panels seem to me to be the cat's meow.
Thanks

Answer
I have built homes here in Florida with a similar panel system. I loved the insulation values and strength of the product, however, there was a down side. I had a hard time finding competent labor to install them. I also had a hard time finishing the exterior as we are a stucco market rather than a siding or Hardee board market. We used a synthetic product called stucoflex, and it did not finish well at all.  However, siding is a good alternative in an area not prone to hurricanes.

If you can find a good installer, these SIPS are wonderful.  I used them as exteriror wall skins and attached them to 20 gage steel studs. I would caution to be careful and research the fire toxicities. Some put off nasty emmissions when burned. Also, if you are replacing existing elements, make sure you have a competent engineer and HVAC person design in safeguards against condensation and mold.
Best of luck with the panels.
