Can this product be used to replace old wet styrene foam board in a hot cover to keep the heat in?
I have a hot tub cover that has old wet foam from 20+ years of use, where the steam has ruined the foam. I would like to get some exterior foam to replace the existing inside foam that would keep the heat in the hot hub, since the outside vinyl is still good. We don't have the funds to purchase a new cover for the old hot tub. We just trying to get buy for a few more years.
Any thoughts or suggestions

Answer: 
Dear KellySharon: No. Tuff-R is made from polyisocyanurate foam, which absorbs water and moisture - clearly not what you would want for a hot tub cover. Use Foamular XPS foam board which does not absorb water. Home Depot carries Foamular in a range of thicknesses.
I hope this is helpful.

Is this good to use in the rafters of a very wet cellar? Everything we've tried has sogged up and fallen down.

Dear Hank: No. Tuff-R is made from polyisocyanurate foam, which absorbs moisture and water. Use XPS foam board, which does not. See: Owens Corning Model 52DD, Home Depot Internet #202085962 Store SKU #307101 Store SO SKU #192627. First staple a thick poly vapor barrier to the bottom of your floor joists, and seal it carefully on the edges where it meets the rim joist -- to block air and moisture leaks. Read More
Dear Hank: No. Tuff-R is made from polyisocyanurate foam, which absorbs moisture and water. Use XPS foam board, which does not. See: Owens Corning Model 52DD, Home Depot Internet #202085962 Store SKU #307101 Store SO SKU #192627. First staple a thick poly vapor barrier to the bottom of your floor joists, and seal it carefully on the edges where it meets the rim joist -- to block air and moisture leaks. Use a generous layer of DAP 230 to seal the seams and edges. Then screw the foam board to the bottom of the floor joists, and carefully seal all of the joints and edges to block air leaks and moisture. The 'Windows and Doors' version of Great Stuff foam works well for larger gaps. DAP 230 is best for standard joints and smaller gaps. The goal is to block air and moisture from reaching any of the wood above.

Based on your description of the "very wet cellar", however, I would start by taking a very close look at the joists and subfloor above and the sill plate around the edge, to make sure there is no rot or mold. Also examine the nails and "joist hanger" brackets that may have been used to attach the floor joists to the rim joist, to make sure rust is not weakening these key fasteners.

Also do everything possible to solve the moisture problem in the cellar. If you have standard concrete or concrete block walls, look for this article: "Waterproofing a basement from the inside" on the FineHomebuilding website.

In addition to their recommendations, here is what we did to solve a similar problem:

(1) Attach 2" thick XPS panels to your basement walls with Loctite Power Grab Heavy Duty Construction Adhesive, Model # 1589157 Internet # 203009262 Store SKU # 495275. 2" thickness provides an effective water vapor barrier and delivers R10 insulation. Carefully seal the joints and edges with a generous layer of DAP 230 sealant, to block air leaks and water vapor. Large gaps can be filled with Great Stuff foam; use the 'Windows and Doors' version in the blue can, which remains flexible as things expand and contract.

(2) Build your interior 2x4 walls in front of the continuous sheets of XPS -- so wood studs do not touch the concrete. Use pressure treated lumber for the sole plate. A Ramset is very helpful to nail the sole plate to the concrete. Look for Home Depot Model # 00022 Internet # 100091715 Store SKU # 107708. (Be sure to wear eye and ear protection.) If the floor is often wet, I would also add a 3/4" thick piece of Veranda PVC trim on the bottom -- to keep the sole plate off the concrete floor. Also leave gaps so any moisture trickling down the walls can run under the sole plate.

(3) Cover the concrete floor with DriCore panels which have a rubber layer on the bottom and a gap to allow water to flow and dry. Look for Model # CDGNUS750024024 Internet # 202268752 Store SKU # 361018 Make sure you also have a drain for the water to run to, and a sump pump. Carefully seal all of the joints and edges with DAP 230 to block air and moisture leaks. Then install 1" XPS foam board over the DriCore panels, and carefully seal all of the joints and edges with DAP 230.

(4) Read up on fire blocking, which many people overlook. This is required at the top of basement walls, along the walls, at the top of stairs, etc. Do a Google search for "How to Firestop Your Basement" from ContractorKurt. Roxul rock wool is a good solution (also available at Home Depot). You can stuff it into the gap at the top of the wall and into the end of floor joist bays. Rock wool is much denser than fiberglass, molds kind of like clay, and stays where you put it. Roxul is also a good solution if you want to boost your insulation and fill the stud bays.

I hope this detail is helpful.

What's the best way to cut this? Will a table saw "melt" it, or will I get a clean, smooth cut?

(2) Home Depot sells a number of 'insulation knife' products with thin blades designed for foam. Enter this phrase into the search option on the Home Depot website to see all of the products.

A standard toothed table or circular saw blade will generate large amounts of foam dust, which sticks to everything and creates a major fire risk. Foam is very flammable and generates toxic gases when it burns.

Also be aware that foam board MUST be covered by an approved 'thermal barrier' in any living space, garage, basement or storage area. The standard is 1/2" drywall. And never install foam board near a source of heat.

I hope this is helpful,

One imporant caveat : foam board is flammable and must be covered by an approved thermal barrier in many applications, so check with your building inspector first.

If this is an issue for walk-in coolers, then Roxul Comfort Board is the best option. It provides R4 per inch, 80% of foam board''s R5 performance, but is not flammable. You can also order a version with white poly facing that would be easy to clean; ask your Home Depot Customer Service desk to order Roxul Rock Board 60 with white poly facing.

Rated 4.5 out of 5 by 2 reviewers.
Rated 5.0 out of 5.0 by Great product to help meet energy codes In existing 2 X 4 walls I find this and other foam boards to be perfect in helping to attain the r-values needed to meet today's energy codes. I rip this stuff on my tablesaw to ensure a perfect fit between the studs and it has worked perfectly every time I've used it and gives a nice and clean appearance. March 2, 2014
Rated 4.0 out of 5.0 by Good Product but makes a mess Product works as it is suppose to, but other products are easier to work with. Cutting is difficult, especially in the thicker product. I used utility blade and it dulls blade very quickly. You get about one blade per cut then it starts pulling on the foil. For thicker product, you have to cut both sides with utility blade because it doesn't break neatly if you cut just one side and then try to snap it off. And it makes a mess when you cut it too. All these little foam pieces get stuck on your shirt and make a mess out of the work area. It is cheaper than other similar products, so if don't mind the mess and spending money on blades, go with this product. And when it is on the wall it looks pretty cool with the foil facing, like a spaceship, but then you cover it up anyways. October 30, 2014
