Underlayment to protect carpet

Was not made in 2ft or 3ft increments. Needed to protect under a 8x̌12 area . Expected a 100sq ft roll to be enough, due to the odd width it was not and therefore 2 rolls were required. Being as 8 and 12 are standard construction widths you would expect the same of this product for coverage. It also tears easily. Using to protect carpet from wood so important that it not have holes.

Doesn’t work as advertised!

Would Not Recommend

The strip you pull off to make it stick to the adjoining row was difficult to start and then it didn’t stick to the adjoining row anyway! Worthless - we just ended up using tape
