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.

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

Dear Hank: There are a number of options. (1) Simply score it deep on one side with a sharp blade, then break the board over the edge of a table.

Dear Hank: There are a number of options. (1) Simply score it deep on one side with a sharp blade, then break the board over the edge of a table. (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.

Dear Zeppy: Sorry for this late reply. Yes, Tuff-R polyiso foam board is ideal for attic insulation. Based on your description, I assume you have a standard 'ventilated' attic with ridge and/or gable vents -- and the 'floor' of the attic (between the joists) is probably filled with fiberglass or cellulose.

Dear Zeppy: Sorry for this late reply. Yes, Tuff-R polyiso foam board is ideal for attic insulation. Based on your description, I assume you have a standard 'ventilated' attic with ridge and/or gable vents -- and the 'floor' of the attic (between the joists) is probably filled with fiberglass or cellulose. If so:

(1) Start by sealing every air leak you can find into your attic. This is almost as important as insulation. Recessed ceiling lights, gaps around vent pipes and ducts, holes drilled for wiring and gaps around internal chimneys are common. Great Stuff foam is a good solution for anything that does not get hot. Cover recessed ceiling lights (which do get hot) with Tenmat covers, and seal the edges with DAP 230. See: Tenmat Model # FF130E, Home Depot Internet # 204286308 Store SKU # 1000012747 Use aluminum flashing to seal the gap around an internal chimney, and seal the edges and joints with 3M Fire Barrier Sealant, Model # CP-25WB+, Home Depot Internet # 100166701 Store SKU # 163096

(2) Both sides of Tuff-R have foil facing, but one side is reinforced -- which you can see when you look at it. Place the reinforced side down.

(3) Seal all of the joints and edges carefully to block air leaks into the attic. The'Windows and Doors' version of Great Stuff foam works well for larger gaps; the cured foam remains flexible to prevent cracks as things expand and contract. DAP 230 is good for smaller seams.

If you live in an area with hot summers, the foil facing on Tuff-R will provide another benefit. A shiny radiant barrier in an open attic can reduce heat gain through the hot roof in the summer by ~28%.

I hope this is helpful,

Mark

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
