"I now know this company is 100% just openly committing fraud. they sales person will tell you they do everything right that they will strip everything down to the studs and put up all new water barrier then install their patent 100% water proof panel that will last a life time. in reality their contractors have confirmed the NEVER tear down the previous water barrier unless they see water damage. they threw the walls over 35yr old green board so the panels do not stick and are not level. On top of that their contractors confirmed these are just your normal every day acrylic panels you get at home depot for $800-1500. They initially quoted me $16,000 for the job but because it was black friday and other deals they lower it to $9000 but I had to decided on spot if they walked out of the house it jump up to $16000. $16000 to rip out your old panel and throw up a normal everyday acrylic panel. Seriously dont just walk away from this company RUN!!!!!!!!! dont given into their fraudulent and predatory sales tactics. I am looking into all legal options to avoid paying for this fraudulent rush scam they are trying to run. I will never ever do business with this company and you shouldn't either"

Insulation questions, answered by experts

In most cases, the building code in your location will determine the minimum amount, in R-value, required for your home's walls, attic, and other spaces. For attics, the minimum R-value amounts start at R30 in the south, R38 in mild climate locations, and R49 in northern states and cold western areas.

Just how long insulation lasts depends on the type of insulation you use. Fiberglass can last between 80 and 100 years, but it's important to start checking fiberglass insulation around the 15-year mark. Spray foam also has a long life span of up to 80 years, while mineral wool can last up to 100 years. Although eco-friendly, cellulose only has a lifespan of 20 to 30 years.

Unless your cellulose insulation is wet, moldy, or showing signs of mildew or pests, there’s no need to remove it before adding new insulation on top of it. Inspect your insulation thoroughly before adding the new insulation, and if you’re unsure how to assess the presence of mold or mildew, talk to a mold remediation specialist near you.

The best R-value for home insulation depends on where you live and where you’re installing the insulation. Your climate zone plays the biggest role in determining the correct R-value, so be sure to know which zone you live in when determining the R-value you need.

Rigid foam insulation boards are one of the best insulation materials for crawl spaces. This material insulates the home well, resists water damage, and won't settle like fiberglass or cellulose. Closed-cell spray foam insulation is another effective insulation that both seals the air and provides excellent thermal protection for hard-to-reach spaces like crawl spaces.
