What Factors Affect the Performance of Blanket Insulation?

Blanket insulation, including fiberglass batts and rolls, is commonly used in walls, attics, floors, and other areas of a building. While the insulation material itself is important, its overall performance also depends on how well it fits the space and the conditions around it.

For homeowners considering insulation improvements, understanding these factors can help when planning a project with Custom Insulation Company, Inc.

Insulation R-Value

R-value measures an insulation material's resistance to heat flow. Generally, a higher R-value provides greater resistance to heat transfer. However, choosing insulation based only on the highest available R-value is not always the best approach.

The appropriate R-value depends on factors such as the part of the building being insulated, available space, and the specific requirements of the project.

Proper Fit and Coverage

Blanket insulation needs to fit the space properly. Gaps, spaces around obstacles, or areas where insulation has been compressed can reduce its effectiveness.

Careful installation helps ensure the insulation provides more consistent coverage across the intended area.

Installation Quality

Even good-quality insulation may not perform as expected if it is installed incorrectly. Poorly fitted batts, gaps around framing, or compression can create areas where heat moves more easily.

Professional installation can help address these details and ensure the material is installed according to the requirements of the space.

Moisture and Water Exposure

Moisture can affect insulation performance and may contribute to other building problems. Leaks, condensation, or excessive humidity should be addressed rather than simply covering the affected area with new insulation.

Identifying potential moisture sources before an insulation project can help protect the long-term performance of the building assembly.

Air Leakage

Insulation and air sealing serve different purposes, but they work together. Air can move through gaps and openings around framing, penetrations, windows, doors, and other areas, potentially reducing the overall effectiveness of an insulated building envelope.

Addressing significant air leakage can complement a blanket insulation installation and improve overall energy performance.

Age and Condition

Over time, insulation may become damaged, displaced, compressed, or affected by moisture or pests. Older insulation is not automatically ineffective, but its condition should be considered when evaluating an existing insulation system.

A professional assessment can help determine whether insulation needs to be repaired, supplemented, or replaced.

Get More From Your Blanket Insulation

Blanket insulation performance depends on more than the material's R-value. Proper fit, complete coverage, installation quality, moisture control, air sealing, and the condition of existing insulation can all make a difference.

If you are considering new or upgraded insulation, Custom Insulation Company, Inc. can help evaluate your building and determine an approach suited to its specific needs. A properly planned insulation project can help create a more comfortable and energy-efficient indoor environment.
