Easy to work with

Would Recommend

Incredibly easy to work with and affordable. I placed it around the bottom of an out building before installing the skirting to ensure water pipes would stay warm. No frozen pipes!

Underskirting for RV

Would Recommend

Purchased this product to use as an underskirting for my RV. So far it has proven to be helpful in reducing heat loss since we live in our RV full-time.

foam board insulation

the foam board insulation met my needs, was able to get it home and installed without damaging the foam board. I added the foam insulation in a storage area to cover up the itchy fiberglass insulation

Works as advertised

Would Recommend

Lite weight, cuts easily with a box cutter. May be glued or nailed. A drill driven screw broke the skin, therefore i cannot recommend using that type of fastner.

smoth surface

Would Recommend

Very reasonably priced and very sturdy. What I liked about it it doesn't wrap like plywood does. It also takes paint very nicely.

Foam Board Insulation

Would Recommend

I used it on the underside of the metal roof of my barn. There is definitely a big difference in the inside temperature versus the outside temperature. There is about a twenty degrees difference in the inside temperature. Summertime in Texas average afternoon temperature is about 103 degrees outside. The inside temperature in the barn is 83 degrees. With a fan blowing it is comfortable working inside the barn.
