Roof felt as a sound barrier.

Roof felt lies between the roof decking and the roof barrier and is implemented as an added layer of protection from rain ice and snow. Why is roof felt needed. The barrier layer blocks the transmission of airborne sound like voices and outdoor noises while the foam layer isolates and protects the barrier and dampens vibratory sound such as the type caused by impacts or construction work. It is applied under all other roofing materials as an added layer of protection from severe weather.

Roofing underlayment is a water resistant or waterproof barrier material that is installed directly onto your roof deck. Roofing felt also known as tar paper serves as both an extra layer of protection between the shingles and the plywood and as a temporary moisture barrier until all the shingles are in place. Nail metal drip edge flashing which bends over the roof and down the edge of the facing board on all roof edges. Roberts super felt underlayment is an excellent choice for noise proofing a floor especially with laminates hardwoods and engineered wood.

About twice as expensive as polyethylene foam felt underlayment is a wise choice if sound absorption is your main objective and if your budget can handle the added cost. Installing roof felt is a two person job. Typically sold in 36 wide rolls roof felt is essentially an underlayment to the barrier protection of your roofing system.

Impact noise such as that coming from an upstairs apartment is harder to deal with than airborne noise. There are three main types of roofing underlayment. The use of roofing felt or 15 pound felt as a building house wrap or vapor barrier and the permeability moisture problems and indoor condensation problems that may occur vapor barriers and condensation in buildings. Soundproofing is a way to lessen sound pressure from room to room.

Recycled felt underlayment is about four times heavier than foam and thus denser. The felt is made from recycled fibers compressed and heat treated to form a rich sound absorbing material. When and why condensation occurs inside buildings explains the problems caused by excessive indoor condensation explains how moisture enters building wall and ceiling cavities.
