Today we will compare the durability of spray foam insulation vs fiberglass mineral wool, fiberglass, cellulose, and cork insulation as well as discuss the reasons why.

 

Testing the Status of Your Home Insulation

 

As we are addressing the longevity of home insulation, it naturally leads us to look at the insulation in our own homes and wonder how it’s currently preserving. Most likely, you are already aware of different ways to tell how your insulation is doing. Let’s go over a list of ways to do so:

 

1. Visual inspection: first start by taking a look at your insulation thickness, material conditions, and whether the insulation has been properly installed, especially in easily accessible areas like your attic, basement, or crawl space. Ensure that the insulation covers the entire area without any gaps or compression. Look for signs of damage such as moisture stains, mold growth, or pest infestation.

 

2. Thermal imaging: A thermal imager can help you pinpoint heat and identify potential insulation deficiencies in walls, windows, roofs, and basements.

 

3. Air infiltration testing: A pressure test, known as a blower door Test, aided by smoke pencils or thermal imaging, can help you locate leaks accurately.

 

4. Surface temperature: Take the surface temperatures of walls, floors, and ceilings with an infrared thermometer.

 

5. Heating & air conditioning bills: This is something you’re likely well aware of. If you’re seeing major fluctuation in your bills, that should be cause for concern.

 

6. Professional Assessment: For comprehensive and precise evaluations, seeking assistance from energy audit specialists equipped with advanced tools and expertise, such as Ecothermix’s professionals, is advisable.

 

In the case of subpar insulation levels, selecting the right insulation material becomes crucial. Durability emerges as a primary criterion, underscoring the significance of choosing materials capable of withstanding the test of time. In this respect, the R value of spray foam and its other attributes are a league of their own, offering unparalleled durability and performance to ensure lasting comfort and energy efficiency in residential and commercial spaces alike, lasting 50 to 100 years or more if properly handled. Thus spray foam insulation kits 1000 sq ft in application or more will also maintain the outer envelope of the home very well.

Spray Foam: A Durable Insulation Option

 

A spray foam insulation company creates the material through a chemical reaction between two liquid components: polyol resin and isocyanate. When these components are mixed together, they undergo a rapid expansion process, forming a foam with excellent insulating properties. This expansion occurs as a byproduct of the chemical reaction. The foam then hardens and cures within a short period, creating a seamless and durable insulation barrier. The unique cellular structure of spray foam traps air and provides superior thermal insulation, effectively reducing heat transfer and improving energy efficiency.

 

Polyurethane foam is a lightweight and sturdy material widely utilized in construction for its excellent thermal insulation properties. Its durability stems from its resistance to both chemical and physical degradation. Closed cell spray foam (R value of 6 or 7) remains unaffected by rot, corrosion, and decomposition, even when exposed to moisture, allowing it to maintain its insulating effectiveness for decades. Even in environments with constant water contact or high humidity, spray foam remains water-proof, rendering it ideal for such conditions. 

 

A key contributor to its long lifespan is its resistance to biological factors. Unlike many organic materials, spray foam closed cell does not provide a conducive environment for the growth of mold, fungi, or insects. This property is particularly crucial in building structures, where biological damage could significantly shorten the insulation’s lifespan. Moreover, insulation applied using a closed cell spray foam kit boasts high mechanical strength, resisting compression and deformation, ensuring that its shape and functionality endure under significant mechanical loads. This resilience is especially vital in building and structural applications, where materials may face constant pressure and vibration. Additionally, the temperature stability of foam contributes to its durability, maintaining its insulating properties across a wide temperature range, from extreme cold to high heat. This quality allows spray foam insulation and its high R value to be utilized effectively in various climatic conditions without having to worry about whether its insulating capabilities will deteriorate over time. 

 

Other Materials

 

Mineral Wool

Mineral wool, produced from mineral fibers like glass or rock, is a popular insulation material known for its impressive heat and sound insulation properties. However, its insulation ability as well as its durability fall short (lasting only 20-30 years) compared to spray foam due to several factors:

• Mineral wool is prone to moisture absorption, which can diminish its insulating effectiveness and hasten its deterioration. 
• In high-humidity environments, it becomes a breeding ground for mold and fungi, resulting in a shorter service life.
• Moisture absorption may contribute to nearby metal corrosion.
• Over time, insulation may settle or compress, reducing effectiveness.
• Gaps allow air infiltration, diminishing energy efficiency.
• Regular maintenance may be needed for moisture management or pest control.
• Not always compatible with certain materials or construction methods.
• Exhibits lower resistance to mechanical stress and may be prone to damage from vibrations.

 

Fiberglass

Fiberglass is another popular option, composed of thin glass fibers, typically manufactured by melting glass and then extruding it into fibers. These fibers are then woven into a fabric or compressed into mats. Though simple to install, there are some of the problems with it, which cause it to typically only last 20 to 30 years.

• Gaps or voids in the insulation installation can allow for air infiltration, diminishing the overall energy efficiency.
• Easily shrinks, leaving space for moisture and pests to accumulate. These will require control measures to be taken.
• Not a particularly high R-value for insulation.
• Improper installation techniques or inadequate sealing of joints and gaps can compromise performance and longevity.
• Often incompatible with construction materials and methods

Cork Insulation

 

Cork insulation, derived from cork oak bark, is lauded as an environmentally friendly and naturally insulating material known for its resistance to moisture and mold. However, its durability is tempered by factors such as mechanical fragility and vulnerability to temperature fluctuations. While offering good insulation properties, cork insulation is less resistant to mechanical loads compared to polyurethane foam and at times performs worse and worse as temperatures fluctuate. On average, cork insulation has a service life ranging from 30 to 50 years.

 

Ecowool: Eco-Friendly Choice with Durability Challenges

 

Ecowool, crafted from recycled paper, is valued for its eco-friendliness and effective heat and sound insulation ability. However, its durability is compromised by vulnerabilities such as moisture absorption and susceptibility to biological activity. In high-humidity environments, ecowool may absorb moisture, leading to diminished insulation properties and fostering the growth of bacteria. Consequently, its average service life is approximately 20 to 30 years, reflecting its durability limitations.

Spray Foam Insulation 

In comparison with other common insulation materials such as mineral wool, cork insulation, ecowool, and fiberglass, polystyrene foam demonstrates superior durability. With a service life spanning 50 to 100 years or more, polystyrene foam owes its longevity to its robust resistance to chemicals, moisture, temperature swings, and pests as well as its mechanical strength. These exceptional properties render spray foam insulation closed cell an ideal choice for long-term thermal insulation in buildings and structures, delivering effective protection and savings over many decades. 

Final Thoughts

Spray foam stands out as the most durable insulation material among those on the market, rendering it the preferred option for those seeking a reliable and enduring insulation solution. It’s worth noting that the durability of spray foam insulation closed cell is contingent upon proper installation and operating conditions. Thus, adhering to manufacturer recommendations for installation and maintenance is crucial for maximizing the longevity of polyurethane installed using a spray foam insulation machine.
