Fiberglass Insulation: What You Need to Know
Fiberglass Insulation: What You Need to Know
Blog Article
When it comes to insulating your home or business, there are several materials to choose from, each with its own set of pros and cons. One of the most widely used and historically popular choices is fiberglass insulation. At Renton Spray Foam Insulation, while our specialty lies in high-performance spray foam, we believe in educating our clients about all insulation options so you can make the best decision for your specific needs.
Let’s dive into everything you need to know about fiberglass insulation: what it is, how it works, its benefits, drawbacks, and how it compares to spray foam.
What is Fiberglass Insulation?
Fiberglass insulation is made from extremely fine glass fibers. It typically comes in two forms: batts (or rolls) and loose-fill. Batts are pre-cut panels that are designed to fit between standard wall studs, floor joists, and ceiling rafters. Loose-fill fiberglass is blown into attics or wall cavities using specialized equipment.
This material works by trapping pockets of air, slowing down the spread of heat, cold, and sound within a building. Because of its affordability and availability, fiberglass has been a go-to insulation choice for decades.
Benefits of Fiberglass Insulation
- Cost-Effective: One of the primary advantages of fiberglass is its low upfront cost. It’s often the most budget-friendly insulation material on the market.
- Availability: You can find fiberglass insulation in nearly every home improvement store across the country, making it easy to source and replace if needed.
- Fire Resistance: Fiberglass is naturally non-combustible, which means it won’t catch fire and spread flames. This is a key safety feature for many homeowners.
- Ease of Installation: For straightforward spaces with standard stud and joist spacing, fiberglass batts can be installed relatively quickly.
- Sound Dampening: While not specifically designed for acoustic performance, fiberglass does help reduce noise transmission between rooms.
Drawbacks of Fiberglass Insulation
Despite its many benefits, fiberglass isn’t without its downsides:
- Air Leakage: Fiberglass insulation does not seal air gaps. Without a proper air barrier, it allows air to pass through, which can reduce overall energy efficiency.
- Moisture Issues: When fiberglass insulation becomes wet, it loses much of its insulating power and can foster mold growth if not dried or replaced.
- Installation Gaps: Improper installation can lead to gaps, compression, or misalignment, significantly reducing its effectiveness.
- Health Concerns: Fiberglass particles can irritate the skin, eyes, and lungs during installation. Proper protective equipment is essential.
Where Fiberglass Works Best
Fiberglass insulation is commonly used in attics, wall cavities, and floors. It is especially well-suited for new construction projects where walls are open and accessible. Retrofitting fiberglass into existing walls can be more challenging unless you opt for the loose-fill version, which requires professional equipment.
Fiberglass vs. Spray Foam Insulation
At Renton Spray Foam Insulation, our primary focus is on spray foam because of its superior performance in many critical areas. Here’s a quick comparison:
- R-Value: Spray foam has a higher R-value per inch compared to fiberglass, which means better thermal performance.
- Air Sealing: Spray foam acts as both an insulator and an air barrier, helping to eliminate drafts and reduce energy loss.
- Moisture Resistance: Closed-cell spray foam is water-resistant and can even add structural integrity to buildings.
- Longevity: Spray foam insulation tends to last longer without degrading in performance over time.
That said, fiberglass still has its place, particularly in projects where budget constraints or accessibility issues are a concern.

Choosing the right insulation depends on a variety of factors including your budget, the location of your home, specific performance needs, and your long-term energy goals.
