Effective Knee Wall Insulation Techniques: Optimize Energy Efficiency with EPS

Update Understanding Knee Wall Insulation: Why It Matters Knee walls, which are typically located in attic spaces, play a crucial role in maintaining energy efficiency and comfort in homes. Knee wall insulation involves ensuring that these walls are properly insulated to prevent drafts and heat loss. This is especially important in climates that undergo extreme temperatures, as inadequate insulation can result in higher energy bills and uncomfortable living conditions. Choosing the Right Insulation Material When it comes to insulation materials for knee walls, faced Expanded Polystyrene (EPS) is becoming increasingly popular. This material not only provides excellent thermal resistance but also acts as a vapor barrier, which is critical for homes located in humid climates. However, using faced insulation can sometimes lead to concerns about creating a double vapor barrier if another moisture barrier is applied over it. The key is in the installation technique—ensuring that shops and homes are preserved from moisture and mold while maximizing efficiency. A Seamless Approach to Air Sealing Incorporating a rigid foam air barrier along with knee wall insulation can enhance energy efficiency significantly. The insulation must be properly sealed on all sides to prevent air leaks that could undermine its effectiveness. For example, Mike Guertin, a prominent figure in the construction community, emphasizes air-sealing as a necessary step in achieving high energy performance for spaces enclosed by knee walls. His recommendations include using materials like acoustical sealant or expanding spray foam to create a tight seal.
