Fibreglass Wall Insulation: Properties, Manufacturing, and Benefits
Recent research sponsored by the NAIMA and conducted by ICF Consulting reveals that about 89% of homes in the US are underinsulated. The main reason for this is that people are not very aware of its impact.
Fiberglass wall insulation, which does not contribute much to the aesthetics of the building, is generally overlooked in terms of its importance. However, through this blog, we want to highlight why it is essential. Let’s dive in!
How is Fiberglass Made?
Fiberglass wall insulation is created by melting glass and then spinning or drawing the molten material into thin strands of fiber. These strands are then bundled together and compressed into mats or batts that can be used for insulation.
The process involves:
Melting
Raw materials like soda ash, limestone, and sand are melted in the furnace at a very high temperature. Upon drying, a glass-like material is formed, and it can be used to create various types of materials.
Creating Fibres
This melted material is passed through small holes that create long and thin fiberglass.
Binding
The thin layers are compactly binded using epoxy or adhesive to form mats, batts, or rolls.
Finishing
These mats are then cut to specific sizes for different types of installations, such as in wall cavities, attics, or floors.
Fiberglass wall insulation comes in different forms, such as batt insulation (pre-cut panels), loose-fill insulation (small particles), or spray foam (when mixed with other materials).
Properties of Fiberglass Insulation
Fiberglass wall insulation boasts several remarkable properties that make it a superior choice for insulation in both residential and commercial buildings. These properties include:
Thermal Resistance
The primary role of fiberglass wall insulation is to resist heat flow. These materials typically hold an R-value that determines the effectiveness of the insulation. The value typically ranges between R 2.2 and R 4.3 per inch of thickness. The higher the R-value, the better the insulation's performance.
Fire Resistance
Fiberglass is non-combustible, and so it enhances the safety of residential or commercial spaces. Installing them ensures that the walls do not catch fire or contribute to the spreading flames.
Moisture Resistance
While fiberglass doesn't absorb water, it can retain its insulating properties even in moist conditions. However, if installed in areas with high moisture, it’s often paired with a vapor barrier to further protect against dampness.
Soundproofing
While providing insulation, it is also prominent for its soundproofing property. If a building is requiring both insulation and soundproofing, instead of addressing each aspect individually, it can be combinedly solved using fiberglass wall insulation.
Durability
Fiberglass wall insulation typically provides a lifespan of 80–100 years. Fiberglass is extremely durable and does not degrade or lose its insulating effectiveness over time. With proper installation, it can last for decades.
How Does Fiberglass Help in Insulation?
The most crucial role of fiberglass wall insulation is to improve energy efficiency by reducing heat transfer.
Here’s how it works:
Thermal Insulation
Fiberglass works by trapping air within its fibers. Air is a poor conductor of heat, so the trapped air pockets prevent heat from escaping in the winter or entering during the summer. This helps to maintain a stable indoor temperature and reduces the need for heating and cooling systems to work overtime.
Energy Efficiency
By reducing the amount of energy required to heat or cool a building, fiberglass wall insulation helps lower utility bills. It can lead to long-term savings while reducing the environmental impact of heating and cooling systems.
Reducing Condensation
Proper installation of fiberglass insulation can prevent condensation buildup on walls, especially in colder climates. This reduces the risk of moisture-related issues such as mold and mildew, which can degrade the structural integrity of the building.
Healthier Indoor Environment
Insulating your home with fiberglass also helps to keep out dust, allergens, and pollutants. The insulation keeps the internal environment healthier by maintaining better air quality.
Conclusion
For insulation, fiberglass is not only the material that works; there are other materials and techniques as well, through which you can achieve an optimal living space. If you need such services, you can contact Draft Busters, Inc.
