Dear Tim,
I have had a couple of companies come to give me an estimate for siding on my home. They both told me that the type of insulation they use is the best and that the other guy's is the worst. I'm not sure who to believe. It has been a struggle to find any information about these insulations on the internet, so I hope that you can help me. The one contractor showed me 3/8" double foil foam insulation and the other showed me Dow/Tenneco (SuperGuard +) insulation with perforations. They told me that those perforations were what would keep the vinyl siding from buckling. Can you help me out and give me some information on these types of insulation?
Thank you,
Bonnie Layman

Bonnie,
Why not consider the vinyl sidings that come with the insulation built into them? I wrote a column about them two years ago. The first one to the marketplace was CraneBoard made by Crane Plastics. Crane was the first company to make vinyl siding so they have a proven track record. This same company also has a full line of realistic trim pieces that are foam filled. I would give it a serious look if I were you.
