Understanding Insulation R-Value
The key measurement for insulation performance is R-value, which indicates how well a material resists heat transfer. Simply put, the higher the R-value, the better the insulation’s performance.
Most residential insulation products range from R-3 to R-38, depending on the material and application. Thicker insulation generally provides a higher R-value.
For the best results, it is important to consider the entire wall, including siding, house wrap, sheathing, and drywall, and ensure proper installation to maximize performance.
At Northville Lumber, our experts help you choose the right insulation for attics, walls, basements, and crawl spaces to improve comfort, efficiency, and long-term energy savings.
