Closed Cell Foam Pad R Value

Pads with higher r values do this more effectively than pads with lower r values.

Closed cell foam pad r value.

Before and after this one i d used the traditional closed cell foam pads with smooth surface. Closed cell foam has a higher r value than open cell foam usually about 6 0 per inch. A sleeping pad r value measures a sleeping pad s ability to prevent heat loss to the ground when you lie on it at night. In such circumstances i will often double up carrying both a closed cell foam mat in addition to a lightweight inflatable.

Just like for open cell foam r values are additive. Though it is less durable in comparison to traditional pads and its ridged surface may not be liked by everyone. But in the end if you don t mind the added weight or cost a sleeping pad with a higher r value is certainly a nice piece of gear to own. Closed cell spray foams are between 2 and 4 lbs.

They sport an r value of 6 0 8 0 per inch of insulation about double their open cell foam counterparts. Open cell spray foam has an r value of about r 3 7 per inch while closed cell spray foam has an r value that may be as high as r 6 5 per inch. The durable closed cell foam pad adds insulation and helps protect the inflatable pad from punctures or other damage. R value isn t a measure of warmth per se but of a pad s ability to prevent the loss of the warmth that your body generates.

Camping on snow also requires more insulation. This higher rating makes closed cell foam better at keeping heat in or out of a structure. If you want to install spray foam in a stud wall and price is no object then it would seem to make sense to specify closed cell spray foam right. R value measures a mat s resistance to heat flow.

But some closed cell foams like tiger foam s e84 closed cell formula have even higher ratings that go up to almost 7 per inch. Open cell spray foam has an r value of about r 3 7 per inch while closed cell spray foam has an r value that may be as high as r 6 5 per inch. Closed cell foam r6 r8. If you want to install spray foam in a stud wall and price is no object then it would seem to make sense to specify closed cell spray foam right.

Two inches of closed cell foam will provide r12 r14 of insulation. Because r value is additive consider using a closed cell foam pad underneath an insulated moderate or high r value air pad or self inflating pad.
