Omhullingsplaten

Omhullingsplaten, often translated as "enveloping plates" or "sheathing plates," are a construction component used in various building applications. Their primary function is to provide structural support, rigidity, and a substrate for subsequent finishes. Typically made from materials such as plywood, oriented strand board (OSB), or fiber cement, omhullingsplaten are attached to the exterior of wall framing or to roof rafters and trusses.

In wall construction, omhullingsplaten serve to brace the structural frame, resisting lateral loads like wind. They also act as a continuous surface to which weather-resistive barriers and cladding materials are applied, contributing to the building's thermal and moisture protection. The sheathing creates a solid plane, preventing drafts and ensuring a stable base for siding, stucco, or other exterior finishes.

Similarly, on roofs, omhullingsplaten form the deck onto which roofing materials are installed. They transfer the roof loads to the supporting rafters or trusses and provide a smooth, continuous surface for underlayment and shingles, tiles, or metal roofing. The thickness and type of omhullingsplaten used are determined by structural requirements, local building codes, and the type of building and its intended use. The proper installation of omhullingsplaten is crucial for the overall integrity and performance of the building envelope.
