Insultarp
If you are in the Phila. PA area we stock the insultarp at Radiant Heat Supply 610-466-0500. We sell quite a few of them.0 -
okay
you've piqued my curiosity and imagination. What, exactly, is an insultarp ?0 -
Insultarp
Quoting from the product spec's: Insultarp is an underslab insulation tarp that has a closed cell foam and aluminum reflective material within a poly coating. It is mosture impermiable and reflects 97% of the energy radianting downward. The look like big tarps black on one side white on the other and come in 6' x 25' & 50' and 12' x 25 & 50' sizes and are 1/2" thick. They are seamed at the perimeter and have brass gromets to hold them in place on the ground. The are also effective vapor barriers. Our contractors like them and say they install very quickly compared to foam board and are practically indestructable.
We sell a lot of them.0 -
Insultarp
was used on this slab overpour. I like it because it provides a good separation between the old slab and new slab. The R-value is the same as 1" of Blueboard (R-5), it's thinner than Blueboard, relatively easy to install and it doesn't break when you step on it.

Art...
...certainly exists in that tubing layout. Looks like the "quilting" made GREAT guidelines! Why the tighter spacing to your left?0 -
Tighter spacing
On this job, we did a tight (9") barrier at the windows and opened it up to 12" once we got about 3' away from the windows. Actually, the tightest spacing is in the kitchen to the right. We had to go 6" because of the reduced floor area from all the cabinets they had.

Foot-in-mouth
Is that "quilting" or 6" wire "mesh" for attaching the tube/reinforcing slab? both? Hard to tell from photo.0 -
Welded wire mesh
We could have used the E-Z clips, but I forgot we had them.
Thanks to Mark Eatherton for the photo.

Have been using foil/double bubble/poly. 8'X 125' and smaller. Insultarp sounds similar in performance and maybe withstands more "abuse".0 -
That looks as nice to use as the little clips I found that allow a supported drywall corner without solid backing. Truly invaluable in older homes where you have to remove the plaster/lathe.
My good drywaller (lost him to macular degeneration recently) fell in love with them...0 -
Nice Job
Alan what a nice neat job. It looks like your customers have a great job on the way. Many years of comfort and enjoyment

E-Z Clips
Alan
Where does a guy get these clips? Are they made for wire mesh? Or do they also make them for rebar.
Your work looks great, by the way.

Great looking counterflow
Alan, I was just curious what your ODT was for that installation. How would you design it for an ODT of -20F?

Insultarp
If you are in the New York area it can be purchased through Blackman Plumbing Supply, the rep is Rathe Associates.0 -
ODT
was +32° and even though it had high ceilings and lots of glass, the numbers were conservative, mainly because the finished floors were concrete. The average heat loss was between 20-25 BTU/[].
If the ODT was lower, our spacing would have been tighter.

white side up
Sorry to be a pain but I thought Insul-tarp is supposed to be installed white side up? Your pictures show black side up...am I wrong?

white side up
You are correct Mike, It is supposed to be installed white side up. Sometimes the concrete guys lay the tarp white side down. Also some materials like double bubble go black side up (I think). I wonder if it really affects performance. I think a test is in order.
Just my opinion,

This came up before
and I called my distributor (Northern Wholesale Supply in Lino Lakes, MN); they didn't think it made a difference.
I'd like to know if it does make a difference.

Which side is up
I spoke with the people at Insulation Solutions about whether ther is an up side or a down side. They said the white side is usually faced upwards...something about the foam layer being closer to the bottom. But then they said that the reflectivity of the product didn't change when used with the white side down. They say the R value of the insulation stays the same no matter which side faces up. Interesting.
If I were to use the Insultarp outdoors it would be nice to put it down with the black side up just to cut down on the glare from the sun.0
