Tar Paper Asphalt Impregnated Roofing Felt Paper

 

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.

Tar paper installation:

The process of installing tar paper is called tar paper roofing. It is typically installed on roofs over the sub-roof prior to the installation of roof shingles or gravel. In driving rains, it is possible for water to be pushed under shingles. The tar paper works as a secondary line of defense, preventing the water from reaching the interior wood structure.

Tar paper is also applied as sheathing on exterior walls. It is installed under the siding. This not only prevents water from reaching the interior wood structure, but it also helps prevent the loss of heated or cooled interior air. Tar paper is sometimes used as a vapor barrier and cushioning beneath wood floors, keeping the sub-floor dry and helping to prevent wood floors from squeakig.
