Fiberglass Insulation: Affordable & Effective Home Comfort

Fiberglass insulation is made from fine strands of glass that trap air, providing a highly effective barrier against heat flow. It’s available in different forms, including batts/rolls and loose-fill (blown-in), making it suitable for a variety of applications. Fiberglass is a popular choice for homeowners because it is cost-effective, energy-efficient, and relatively easy to install. However, ensuring proper installation is key to its effectiveness.

Types of Fiberglass Insulation

Batt & Roll Fiberglass

Batts are pre-cut sections of fiberglass insulation that fit between studs, joists, or beams. Rolls are similar but come in longer sheets. These types are best suited for open wall cavities, attics, and floors.

Blown-In Fiberglass

Blown-in insulation is loose-fill fiberglass that is blown into spaces using a machine. This form is ideal for attics, hard-to-reach areas, and retrofit applications. It fills gaps and irregular spaces more effectively than batts.

Common Applications of Fiberglass Insulation

Fiberglass insulation is commonly applied in:

  • Attics: Helps maintain temperature control and prevents heat loss.
  • Walls: Provide soundproofing and insulation against temperature fluctuations.
  • Floors and Crawl Spaces: Reduce heat loss and moisture penetration.

R-Value: Understanding Performance

The Importance of R-Value

R-value measures the insulation’s ability to resist heat flow. The higher the R-value, the better the insulation’s performance. Fiberglass insulation typically has an R-value between 2.9 and 4.3 per inch, depending on the type and density.

For optimal performance, choose an R-value suitable for your region and home type. A professional installation ensures your fiberglass insulation delivers maximum benefit.

Benefits of Fiberglass Insulation

Why Choose Fiberglass?

  • Cost-Effective: One of the most affordable insulation options.
  • Energy Efficient: Helps reduce heating and cooling costs by maintaining a stable indoor temperature.
  • Non-Combustible: Does not burn or emit toxic fumes if exposed to fire.
  • Soundproofing: Offers additional benefits by reducing noise transmission between rooms.

Potential Issues With Fiberglass Insulation

What to Consider

  • Installation Sensitivity: Proper installation is critical. Gaps, air leaks, and compression can reduce its R-value and compromise performance.
  • Air Leakage: If not properly sealed, fiberglass can allow air to pass through, reducing its effectiveness.
  • Compression: When compressed, the fibers lose their ability to trap air, lowering the insulation’s Performance.
