Application
Synthetic underlayment is a popular roofing material that offers several advantages over traditional felt paper underlayment. Some common applications of synthetic underlayment include:
1. Roofing: Synthetic underlayment is commonly used as an underlayment material for various types of roofing materials, such as asphalt shingles, metal roofing, and tiles. It provides a water-resistant barrier that helps protect the roof deck from water infiltration.
2. Waterproofing: Synthetic underlayment can also be used for waterproofing applications in areas such as basements, decks, and foundations. Its water-resistant properties make it an effective barrier against moisture.
3. Temporary Coverings: During construction or roof repairs, synthetic underlayment can be used as a temporary covering to protect the interior of a building from water damage until a permanent roof covering is installed.
4. Sound Insulation: Synthetic underlayment can provide some degree of sound insulation, reducing noise from rain and other external sources.
Features
1. Water Resistance: Synthetic underlayment is highly water-resistant, providing a reliable barrier against moisture infiltration. This helps protect the roof and the underlying structure from water damage.
2. Lightweight: Synthetic underlayment is lightweight compared to traditional felt paper underlayment, making it easier to handle and install. Its lightweight nature also reduces the overall load on the roof structure.
3. Durability: Synthetic underlayment is durable and resistant to tearing, punctures, and UV exposure. It can withstand harsh weather conditions, making it a long-lasting roofing material.
4. Breathability: Some synthetic underlayment materials are designed to be breathable, allowing moisture vapor to escape from the roof space. This helps prevent issues such as mold and rot.
5. Flexibility: Synthetic underlayment is flexible and easy to work with, conforming to the contours of the roof surface. This flexibility makes it suitable for various roof shapes and designs.
