Sleeper walls are a specific type of wall used primarily in construction, particularly in the context of supporting floors or providing a base for a raised floor. They differ from timber sleeper walls used in landscaping and have distinct functions and characteristics.
What Are Sleeper Walls?
Sleeper walls are short, low-height masonry walls typically constructed from brick or concrete blocks. They are built in the subfloor space of a building to support floor joists, ensuring the floor is level and stable. These walls are usually placed on the foundation or ground slab and run perpendicular to the floor joists.
Key Functions of Sleeper Walls
- Support: Sleeper walls provide intermediate support for floor joists, preventing them from sagging or deflecting under the weight of the floor and any loads placed on it.
- Ventilation: Sleeper walls often have gaps or openings to allow air circulation under the floor. This ventilation helps prevent moisture buildup, which can lead to dampness, mold, or wood rot in the joists or floorboards.
- Even Distribution of Load: By supporting the floor joists, sleeper walls help distribute the load evenly across the floor, enhancing the structural integrity of the building.
- Insulation: In some constructions, the space between sleeper walls can be filled with insulation material to improve the thermal performance of the building.
Maintenance Considerations
- Moisture Control: Proper ventilation is crucial to prevent moisture-related issues in the subfloor space.
- Structural Integrity: Regular inspection of sleeper walls is essential to ensure they remain in good condition, especially if they are supporting heavy loads.
Sleeper walls are a critical component in certain types of floor construction, providing necessary support and contributing to the overall durability and comfort of a building.
