"We use either 2 inch foam (armaflex) with the aluminum jacket already applied and we buy aluminum 90 fitting covers and use an aluminum butyl tape. If that is not available we use 2 inch fiberglass insulation and cover it with a PVC…"

Solar hot water exterior pipes insulation

Hello everyone,    I was wondering if anyone has experience with insulating exterior pipes for maximum efficiency. Since there are some small gaps in the installation of the insulation, I was wondering if I can use Fasson 0808 Acrylic 2.0 mil foil tape to protect all those small gaps, and in my opinion, extend the life of the insulation by eliminating rain or simply water to penetrate the insulation, and protect the insulation from wind and extreme weather . Any comments? Thank you in advance…See More

"This is a matter of far more than R-values. Average exterior temp, heating load vs. cooling load, interior and exterior RH (moisture drive) ALL enter into the picture. At 6,000 HDD, where Luis is, yours would be a VERY high-risk wall assembly - lots…"

Non-continuous exterior insulation

Greetings everyone,     I have been asked to put 4 inches of closed cell rigid insulation in the first floor of a cottage, but not the second floor, including tape and vapor barrier... I thought that insulation in order to be effective, needs to be continuous... any thoughts? Suggestions?Thank you for your help and Happy Holidays!     Luis See More

"I agree with Sean, as far as he goes... This building wants ALL the exterior wall that sees full exterior temperature to be fully insulated. This looks to me as though the gable walls are fully conditioned all the way to the peak on the inside, and…"
