1. Underlayment for Flooring:
- Felt paper is commonly used as an underlayment for various flooring types, including hardwood, laminate, vinyl, and carpet.
- It provides a smooth and even surface for flooring installation, helping to reduce noise, protect the subfloor from moisture, and improve the overall durability of the flooring.
- Felt paper acts as a moisture barrier, preventing moisture from seeping up from the subfloor and damaging the flooring.
- It also provides a cushioning effect, reducing noise transmission between floors.
2. Roofing Underlayment:
- Felt paper is widely used as an underlayment for roofing applications, particularly under shingles or other roofing materials.
- It acts as a secondary layer of protection against water infiltration and helps prevent leaks.
- Felt paper provides an additional layer of waterproofing and helps extend the lifespan of the roof.
3. Wall Underlayment:
- In wall construction, felt paper can be used as an underlayment behind siding or other exterior wall materials.
- It serves as a moisture barrier, preventing water from penetrating through the walls.
- Felt paper also helps reduce air infiltration and enhances the overall thermal performance of the building.
4. House Wrap:
- House wraps are often made of felt paper or similar materials. They are applied to the exterior walls of a building before siding installation.
- House wraps provide an additional layer of protection against moisture, wind, and air infiltration, helping to improve the energy efficiency of the building.
5. Insulation Backing:
- Felt paper can be used as a backing material for insulation in walls, attics, and other areas.
- It provides a vapor barrier, preventing moisture from damaging the insulation and reducing its effectiveness.
6. Packaging and Cushioning:
- Felt paper is commonly used in packaging and cushioning applications, particularly for delicate or fragile items.
- Its soft and pliable nature helps protect items from scratches and damage during shipping or storage.
Overall, felt paper plays a crucial role in construction and various industries as a cost-effective and versatile material for moisture protection, underlayment, and cushioning purposes.
