Cheap thermal imaging camera

It appears that a startup company called Seek Thermal recently has been offering a $199 thermal imaging camera that attaches to Android or IOS smartphones. What little specifications there are look impressive, for example:

  • Reasonably high resolution, 206x156
  • -40C to 330C range
  • Automatic calibration
  • Nearly 10 frames/sec video

Vapor permeability of polyiso

Attached is a picture of foil-faced polyiso which as a bunch of holes in it. The holes were made with a wall paper removal tool which puts holes in the paper to allow liquid stripper to get behind the paper. I welcome comments on this approach to see of foil faced polyiso could be modified to allow vapor permeability thru the sheet if holes were done on both sides.

ThermoCore Roof SIPs - 8" Panels

Anyone here use or have any experience with the ThermoCore SIPs? They are based out of Indiana and have a 8" polyurethane SIP ( I know about the blowing agents) with a R-50 value that I am considering using for my roof. Zone 4B

Some key points:

1 - I will be air sealing all interior panel joints with a T&G connection, caulk, gasket, and finally a peel & stick tape to ensure complete air tightness.

2 - I will use an ERV

3 - On the exterior I plan on putting a peel & stick butyl membrane that is vapor impermeable and then a standing seam metal roof.

Stranded Bamboo Flooring, Is it a good choice?

We are building a home in Alabama on the coast. We have a crawlspace sealed foundation that is dehumified. We are looking at purchasing 5/8 - 1/2 Stranded, Carbonized, bamboo flooring. We are getting mixed reviews on whether this is a good choice. We've heard the following:

Pro - it's solid engineered so it can be sanded and refinished. The color is the same all the way through. Compared to engeered wood which can only be sanded and refinished once.

Pro - Harder than most woods, and compares to engineered wood in that it's harder to scratch.

Dense pack cellulose rig rental in Philadelphia area

I've decided to make a DIY attempt at installing dense-pack cellulose to a fairly small section of the thermal envelope in my home (which happens to live under a floor, well above grade). I'm looking for the highest-power cellulose blower I can rent, preferably an Intec Force 2 or better, plus a kit for reducing tube diameter to the appropriate level and providing whatever stiffness/bendiness is needed for the circumstance. Anybody know where I can rent such equipment in the Philadelphia area, preferably less than 1 hour drive?

Is there any low- or no-VOC, mold-resistant sheetrock and wall plaster on the market (for basement reconstruction)?

It is my understanding that sheetrock and wall plaster are typically high-VOC items, especially mold-resistant sheetrock.

Also, are carpet tiles a good low- or no-VOC flooring option?

What are the potential problems in an open-cell foam sealed attic when voids and inconsistencies exist?

Along with the open-cell insulation, a radiant barrier roof sheathing was utilized. In most cases, half of the roof framing member (12" TGI truss & 2" X 10" out-looker) surfaces are not encapsulated. There are potential areas where exterior wood framed attic walls are not insulated or sealed off from the attic space. The foam insulation was applied after A/C duct and Can lighting fixtures were in place between the framing members. Most ceilings are cathedral with a tongue & groove wood finish.
