Which is better, Open Cell or Closed Cell Spray Foam?

"Excellent . The Estimator showed up 2 minutes before the appointed time & after a quick 20-minute survey of the exterior of the house, was able to give me a written estimate. The rest of the job was conducted in similar fashion. The installation crew showed up on time, were competant & courteous & completed job on time. When completed, I was asked to walk the job to make sure the cleanup was acceptable. Not enough "cold" time has gone by for me to comment on the reduction in heating costs but as for the work, this outfit gets my unqualified recommendation."

"I am about a few weeks out of my exterior wall insulation, attic spray foam and garage insulation. I feel the big difference in my home. My home is warmer and holds the heat. Tom was very straight forward and upfront. He was my point person for the three day project. He was exceptional. From the initial quote to project completion. After the completion of the insulation, I experienced a strong and significant spray foam smell coming through my bathroom AC flex duct. Tom asked Mike, his operation manager, to come out and check it out the next day. There turn out to be a large hole in my duct. And he fixed it without hesitation. Plus he accidentally broke a spong holder and gave me money for it. I was very please to report the smell instantly disappeared. Also the back office Lindsay and Jeanine who helped me with the the paperwork was phenomenal. Very impressed with the efficiency and diligence. Overall, cannot recommend enough. Don't worry and don't hesitate."
