This underscores the importance of careful handling and installation to minimize compression.
The impact of compressibility extends beyond immediate R-value reduction. Compressed insulation loses its ability to trap air effectively, which is the primary mechanism for thermal resistance in fiberglass. Furthermore, sustained compression can lead to permanent deformation of the fiberglass fibers, further compromising its insulating capabilities over time. A practical scenario involves attic insulation, where foot traffic or storage can compress the insulation, creating thermal bridges and reducing the overall effectiveness of the insulation layer. In wall cavities, overstuffing insulation to achieve a perceived increase in performance will, in fact, compress the material and decrease its actual thermal resistance. These situations highlight the need for proper installation techniques and consideration of load-bearing factors.
In conclusion, the relationship between compressibility and fiberglass insulation with an R-value of 11 is crucial for maintaining its intended thermal performance. Excessive compression diminishes the insulation’s thickness, reduces its R-value, and compromises its long-term effectiveness. Proper installation techniques, careful handling, and awareness of load-bearing factors are essential to mitigating the negative effects of compressibility and ensuring that the insulation performs as designed. Ignoring the effects of compressibility can lead to reduced energy efficiency, increased heating and cooling costs, and a diminished return on investment in insulation materials.
