Feel too cold inside during winter, even with a fireplace and heater? Too hot in the summer, even with the AC on full blast? It might be because your home doesn’t have enough insulation. If you’re not into science stuff, here’s the deal: heat likes to move to colder places. So, in winter, your cozy warmth tries to escape outside, and in summer, outside heat tries to get in.
Good insulation helps by stopping too much heat from moving in or out. It makes an extra wall between the inside and outside of your home. Blown-in cellulose insulation is one way to do this, especially if your home doesn’t have enough insulation.
This kind of insulation works well if you want to add more insulation to your attic.
Keep reading to find out how blown-in cellulose insulation works, how to put it in, and the good and not-so-good things about using it.
What Is Blown-In Cellulose Insulation?
Blown-in cellulose insulation is a kind of insulation used in homes and businesses, and it’s created from plant materials.
Typically, it’s made from wood and recycled paper items like newspapers, cardboard, and office paper. Even though it’s dense and lumpy, it works well because it’s made up of lots of recycled bits. This allows it to go into tight spaces and shape around pipes and ducts in the areas that need insulation.
Benefits of Blown-In Attic Insulation
Blown-in attic insulation is effective in trapping warmth inside your home during winter and blocking excessive heat during summer.
Moreover, homeowners should be aware of additional advantages:
– The insulation preserves the warmth generated by your heater in winter, minimizing the workload on your AC and heater units. This results in significant energy bill savings.
– Certain insulation types, such as fiberglass, offer complete fireproofing.
– Installation is simple and swift with the right blower.
– Fiberglass and cellulose insulation can also provide soundproofing for your attic.
– Blown-in insulation helps reduce condensation by regulating the temperature in your attic.
– It effectively reaches and covers tight nooks and crannies within your attic for thorough insulation coverage.
Blown-In Attic Insulation Pros and Cons
While there are evident advantages to using blown-in attic insulation for homeowners, it’s crucial to consider key pros and cons. Let’s explore some of them:
Pros:
– Blown-in attic insulation can be applied in narrow or small spaces where rolled-up batt insulation may not fit. It efficiently fills gaps between heaters and AC units in the attic, optimizing space utilization.
– Insulation designed for blown-in purposes is cost-effective without compromising the R-value or the insulation’s resistance to conductive heat flow.
– Borates-treated insulation helps prevent insects and vermin from inhabiting the attic. We use a special blend we designed called Pest-Guard which is extremely popular across Hampton Roads for keeping insects from burrowing.
– Blown-in attic insulation can easily be added on top of existing insulation or used to reinforce already insulated areas.
Cons:
– Installation of blown-in insulation can be messy and typically requires professional assistance unless you have experience in the field.
– Overloading insulation in one area may lead to the ceiling sagging.
– Thorough air sealing and the installation of soffit venting may be necessary.
– If blowing cellulose over existing fiberglass, it may be required to cut and refit poorly laid batts and insulate plumbing first.
– Blown-in insulation is susceptible to mold and rot if exposed to excessive moisture over an extended period, emphasizing the importance of sealing the area before installation.
Types of Blown-In Attic Insulation
Having explored the pros and cons of blown-in attic insulation, let’s now delve into the two common types of insulation homeowners typically use for attic insulation: cellulose and fiberglass.
Blown-In in Cellulose Insulation
Comprising recycled paper, cellulose insulation is a budget-friendly choice for homeowners. It incorporates borate, providing resistance to both fire and insects.
With an R-value of approximately 3.5 to 3.8, cellulose insulation tends to maintain its thickness well when correctly applied. For instance, if you blow in around 10 inches of cellulose insulation, it will retain this thickness for an extended period.
Although cellulose insulation is generally irritant-free, it’s advisable to wear safety gloves and goggles when blowing it into your attic.
Blown-In in Fiberglass Insulation
Fiberglass is another commonly used blown-in attic insulation material, often chosen for its cost-effectiveness compared to other options. It boasts an R-value ranging from approximately 2.2 to 2.9 per inch.
Certain fiberglass insulation varieties incorporate up to 53% recycled glass, a feature that minimizes settling after installation. Additionally, this composition enhances its fire resistance, contributing to a safer attic environment.
Blown-In Cellulose vs. Other Types of Insulation
Blown-in cellulose insulation is the most popular choice among our customers in Hampton Roads for insulating already-closed-off walls without undertaking a full remodeling project. While patching and painting are still necessary with blown-in insulation, it proves to be a significantly easier option than completely removing drywall for the installation of roll or batt insulation.
For open and unfinished walls, other insulation types may be more suitable, such as fiberglass roll insulation or fiberglass batts. In attics, blown-in cellulose emerges as one of the top choices, given the challenging-to-reach areas and numerous obstructions typical in ceilings. Many homeowners opt for a combination of blown-in and batt insulation in attics to establish a more comprehensive and effective insulated barrier for their homes.
How Much Does Blown-In Attic Insulation Cost?
Determining the budget for blown-in attic insulation can be challenging as it depends on several factors, including:
– What you want the ending R-Value to be in your Virginia beach home. Since we are in climate 4 an R-value of 19 is the minimum
– The size of your attic and specific areas requiring insulation.
– The material you choose for insulation.
– Labor and professional equipment expenses.
The cost of installing blown-in attic insulation typically ranges from $1,500 to $3,000 for around 1000 square feet of attic space.
On average, we see Hampton Roads homes comfortable with an R-value of approximately 30, equivalent to 10 to 14 inches of total insulation for their attics and thinner for their interior walls.
Is Blown-In Attic Insulation Worth It?
Yes, blown-in attic insulation is a worthwhile investment. This is because it:
– Improve Energy Efficiency: Blown-in insulation helps prevent heat loss in winter and heat gain in summer, easing the load on your heating and cooling system. This can lead to lower energy bills and a more comfortable indoor temperature.
– Increase Comfort: Attic insulation regulates the home’s temperature, minimizing hot and cold spots, and enhancing overall comfort.
– Increase Home Value: A well-insulated attic boosts energy efficiency, making your home more appealing to potential buyers and increasing its resale value.
– Reduce Noise: Attic insulation contributes to noise reduction, creating a quieter and more peaceful home environment.
– Protect Your Home: Insulating the attic safeguards your home from moisture damage, lowering the risk of mold and mildew growth, and preserving the structural integrity.
Considering these benefits, the upfront cost of purchasing and installing blown-in insulation is often justified by the long-term advantages.
The only situations where it may not be worthwhile are when the existing attic insulation is sufficient, doesn’t require replacement or supplementation, and if the homeowner is planning to move soon and won’t fully experience the long-term benefits of the investment.
Factors such as the home’s age, type, and current energy bills should be considered to determine if blown-in attic insulation is a sensible investment. Seeking advice from a professional energy auditor or contractor like us can provide a more tailored assessment.
