What is sheathing?

Sheathing is the outermost layer of material used in construction to protect a structure from environmental elements. It serves as an added layer of protection against water, moisture, and insects. Sheathing can range from rigid boards like plywood or OSB to flexible materials like tar paper or felt. Depending on climate and building codes, sheathing may also include insulation, vapor barriers, and air-barriers. Sheathing is important for protecting a structure from the elements and providing structural support between framing members. It is commonly used on roofs, walls, and floors to provide strength and durability to a building. Properly installed sheathing can improve energy efficiency by keeping out drafts and helping maintain an even temperature throughout the building. Additionally, sheathing can provide protection against water, moisture, and insects. Finally, it helps to ensure the structural integrity of a building by distributing loads evenly among members and helping prevent damage due to vibration or wind forces. Properly installed sheathing can greatly extend the life of a structure and protect its occupants against weather-related threats. Sheathing should be installed by a professional who has experience in the field, as it requires precise measurements and installation techniques to ensure optimal performance and protection. Additionally, periodic inspections should be performed to ensure that all sheathing remains in good condition and is not compromised due to wear or other damage.
