What is tar paper/felt paper
Tar paper/felt paper used to be made by soaking a porous paper made from cotton rag scraps with thinned liquid asphalt. Asphalt, of course, is one the final products that comes out of a catalytic convertor that's used to refine crude oil.
The paper comes in different weights. The most common weights are 15-pound and 30-pound tar paper. The 30-pound tar paper is heavier and has much more asphalt in it.
Using tar paper/felt paper to protect wood sheathing and wood framing members on houses, room additions or outdoor sheds is a fantastic idea. This time-tested product is affordable, it's easy to work with and it's readily available.
The benefits of asphalt felt paper
A benefit of asphalt felt paper is its ability to absorb water, and then slowly evaporate the moisture to the exterior. Dry asphalt felt's permeance is 5 perms. But, when wet, asphalt felt's permeance is 60 perms. So, if water gets behind the asphalt felt due to a leak or condensation, the felt will soak up the liquid water. Due to asphalt felt's high permanence, the absorbed water will gradually dry to the exterior of the building.
