R-Matte Plus-3/Thermasheath-3 is rigid foam plastic thermal insulation board. It's made of environmentally sound, closed cell, polyisocyanurate foam bonded to a durable white-matte (non-glare) aluminum facer and a reflective reinforced aluminum facer.

This Energy Star qualified R-Matte Plus-3/Thermasheath-3 provides R13.1 with dimensions of 2 in. x 4 ft. x 8 ft. This product is designed for exterior and interior, non-structural uses.
  • Rmax polyiso sheathing offers the greatest R-value per inch currently available in a rigid foam board
  • R-Matte plus-3/Thermasheath-3 is applied to the exterior or interior face of wood or metal studs to cover all studs, sills, plates and header constructions, thereby providing insulation over areas not normally covered by insulation products
  • Superior resistance to moisture and vapor in above grade applications
  • Polyiso rigid foam board offers superior fire protection properties compared to any other rigid foam board insulation
  • ENERGY STAR qualified to meet or exceed federal guidelines for energy efficiency for year-round energy and money savings
  • When taped and flashed, the Rmax polyiso board greatly reduces air infiltration and prevents thermal bridging caused by heat and cold transmission through studs
  • Lightweight and easily cut to size

I'm looking to install these insulation boards to a finished dry wall closet....the easiest way for me would be to use an adhesive bond ...like liquid nails...would this be sufficient bonding to the wall ?
Asked by: mrgolf535
It should be sufficient. These panels are very light weight. They are also 4ft wide which I believe is less than standard distance between wall studs so you can also cut these to fit between the studs and press them in for a friction fit.

Can it be used between studs in a bathroom exterior wall?

Asked by: Jonny5
It certainly could be used that way, but bear in mind that it is a vapor barrier. You want to have just one vapor barrier in your walls, either inside or out. A vapor barrier on both will trap moisture within the wall and cause mold and rot. If your exterior wall already has a vapor barrier (vinyl siding, impermeable house wrap, etc.), then you will be better off using breathable unfaced (or paper faced) batt or blanket insulation, i.e. fiberglass or cellulose.

Iit is way to cut to width using a table saw and cut to length using a standard insulation knife (saw). Trimming and shaping it is quick and easy. With a R value of about 6.5 per inch it will be worth the cost.
