A poorly insulated attic can lead to several noticeable issues in your home. Here are some signs that your attic may have inadequate insulation:

1. Uncomfortable indoor temperatures: If your home experiences drastic temperature fluctuations, feels too cold in the winter or too hot in the summer, it may be due to insufficient attic insulation.

2. High energy bills: Poor attic insulation can cause your heating and cooling systems to work harder to maintain comfortable temperatures, resulting in increased energy consumption and higher utility bills.

3. Cold floors and walls: If the floors and walls in your home feel cold to the touch during winter, it may indicate inadequate insulation in the attic, allowing cold air to seep into the living space.

4. Ice dams: In colder climates, poor attic insulation can lead to the formation of ice dams on the roof. Ice dams occur when warm air from the living space melts snow on the roof, which then refreezes at the eaves, causing water to back up under the shingles and potentially leading to leaks and damage.

5. Condensation and mold growth: Insufficient attic insulation can result in condensation, which creates a damp environment conducive to mold growth. If you notice mold or mildew in your attic, it could be due to poor insulation.

6. Uneven heating and cooling: Rooms that are too hot or too cold compared to the rest of the house may indicate poor insulation in the attic, allowing heat transfer between the living space and the outdoors.

To confirm whether your attic is poorly insulated, you can visually inspect the insulation. If the insulation is compressed, damaged, or doesn’t fully cover the attic floor, it may need to be replaced or supplemented. Hiring a professional energy auditor or insulation contractor can provide a more accurate assessment of your attic’s insulation and recommend the best course of action to improve your home’s energy efficiency and comfort.

Overall, blown-in attic insulation is a cost-effective and efficient solution for improving your home’s energy performance and comfort.

There are two popular types of blown-in insulation materials commonly used for attics: cellulose and fiberglass. Determining which is best for your attic depends on your preferences, budget, and specific requirements. Here’s a brief comparison of the two:

1. Cellulose insulation:

• Made from recycled newsprint and treated with fire-retardant chemicals.
• Has a slightly higher R-value (thermal resistance) per inch compared to fiberglass, offering better insulation.
• Dense and heavy, providing excellent sound dampening properties.
• Less likely to settle over time compared to fiberglass, maintaining its insulating capabilities.
• Environmentally friendly due to its high recycled content.

2. Fiberglass insulation:

• Made from fine glass fibers, making it lightweight and easy to install.
• Slightly lower R-value per inch compared to cellulose but still provides effective insulation.
• Less prone to absorbing moisture, reducing the risk of mold growth.
• Often more affordable than cellulose insulation.
• Non-flammable and doesn’t require additional fire-retardant treatments.

Both cellulose and fiberglass insulation materials have their advantages and disadvantages. The best choice for your attic will depend on factors such as budget, local climate, environmental considerations, and desired insulation performance. It’s advisable to consult with a professional insulation contractor to determine the most suitable option for your specific needs. We prefer fiberglass and the reason is that cellulose makes the attic barely unusable once installed since it becomes a very fine powder like substance.  

Insulation can provide sound resistance, helping to dampen noise transmission between rooms and floors. While insulation materials are not specifically designed for soundproofing, they can still contribute to a quieter living environment by absorbing and reducing sound vibrations. It’s important to note that insulation will not completely soundproof a space, but it can significantly reduce noise levels.

Different insulation materials have varying levels of sound resistance:

1. Cellulose insulation: This dense material has excellent sound dampening properties. Its ability to fill gaps and irregular spaces makes it highly effective in reducing airborne noise transmission between rooms and floors.

2. Fiberglass insulation: Fiberglass also offers sound resistance, but to a lesser extent than cellulose. Its lightweight and porous nature allows it to absorb and reduce sound vibrations, but it might not be as effective as cellulose in blocking noise.

3. Spray foam insulation: Closed-cell spray foam insulation can help reduce both airborne and impact noise due to its dense composition and airtight seal. It is generally more effective at sound dampening than fiberglass but may not be as effective as cellulose.

While insulation can contribute to a quieter living space, it’s important to remember that soundproofing requires a more comprehensive approach. Additional measures, such as using acoustic drywall, resilient channels, or mass-loaded vinyl, can further improve sound resistance in your home.

Insulating your home can indeed contribute to an increase in its resale value. While the exact impact on resale value may vary depending on factors such as local market conditions and the overall state of your home, investing in proper insulation offers several benefits that can make your home more attractive to potential buyers:

2. Comfort: Proper insulation ensures a more comfortable living environment by maintaining consistent indoor temperatures and minimizing drafts.

3. Noise reduction: As previously mentioned, insulation can contribute to a quieter living space by dampening sound transmission between rooms and floors.

4. Environmental impact: An energy-efficient, well-insulated home has a smaller carbon footprint, which can appeal to environmentally-conscious buyers.

5. Lower maintenance costs: A properly insulated home may experience fewer issues related to moisture and temperature fluctuations, potentially reducing long-term maintenance costs.

While investing in insulation can enhance your home’s resale value, it is essential to consult with a professional contractor to ensure proper installation and select the most suitable insulation type for your specific needs. A well-executed insulation project can make your home more appealing to potential buyers and potentially result in a higher selling price.

Whether or not you need to remove the existing insulation depends on its condition and the type of insulation you plan to install. In some cases, you may be able to add new insulation on top of the existing material, while in others, it may be necessary to remove the old insulation.

Consider the following factors when deciding whether to remove the existing insulation:

1. Condition of the insulation: If the current insulation is damaged, moldy, wet, or infested with pests, it’s essential to remove it before adding new insulation. Failure to do so can compromise the effectiveness of the new insulation and pose health risks.

2. Insulation type: If you’re installing a different type of insulation, such as switching from fiberglass to spray foam or cellulose, it may be necessary to remove the old material to ensure proper installation and performance of the new insulation.

3. Insulation performance: If the existing insulation has settled or compressed over time and lost its insulating capabilities, removing it and installing new insulation can significantly improve your home’s energy efficiency.

4. Building code requirements: Local building codes may specify the maximum allowable insulation thickness or R-value for your attic. If adding new insulation on top of the existing material would exceed these requirements, you may need to remove some or all of the old insulation.

Before making any decisions, it’s best to consult with an insulation professional who can assess your home’s specific needs and provide guidance on the most appropriate course of action. They can help you determine whether removing the existing insulation is necessary or if it’s possible to enhance your home’s insulation by adding new material on top of the old one.

The amount of insulation you need depends on various factors, including the local climate, your home’s construction, and the specific area you want to insulate. Insulation is measured by its R-value, which represents the material’s resistance to heat flow. A higher R-value indicates better insulating properties.

To determine how much insulation you need, consider the following guidelines:

1. Climate zone: The US Department of Energy divides the country into climate zones, each with different recommended R-values for insulation. Check the guidelines for your region to understand the recommended insulation levels. Here’s a reference for the climate zones and corresponding R-values: https://www.energy.gov/energysaver/weatherize/insulation

2. Area to be insulated: Different parts of your home require different insulation levels. For example, attics generally need higher R-values than walls or floors. The recommended R-values for various areas of your home can be found in the same link provided above.

3. Existing insulation: If your home is already insulated, evaluate the current insulation’s condition and R-value. You may need to add more insulation to reach the recommended R-value for your region and specific application.

4. Insulation type: Different insulation materials have different R-values per inch. For example, fiberglass typically has an R-value of 2.9-3.8 per inch, while cellulose has an R-value of 3.2-3.8 per inch. The required thickness of insulation will depend on the material you choose.

5. Building code requirements: Local building codes may have specific insulation requirements. Ensure you comply with these regulations when determining the amount of insulation you need.

A professional insulation contractor can help you assess your home’s specific needs and recommend the appropriate insulation levels. It’s essential to consult with an expert to ensure your home is adequately insulated, maximizing energy efficiency and comfort.

Both blown and rolled (batt) insulation have their advantages and disadvantages, and the better option for your attic depends on your specific needs, budget, and preferences. Here’s a comparison of the two:

Blown insulation:

• Fills gaps, irregular spaces, and hard-to-reach areas more effectively, providing better coverage and sealing potential air leaks.
• Can be installed more quickly, especially in large or complex attic spaces.
• Offers better sound dampening properties due to its dense composition.
• May settle less over time, maintaining its insulating properties longer.

Rolled (batt) insulation:

• Easier and less messy to install as a DIY project, making it a more affordable option for those with basic home improvement skills.
• Typically made of fiberglass, which is moisture-resistant and non-flammable.
• Allows for precise control over the thickness and R-value of the insulation.

While both options can provide effective insulation for your attic, blown insulation is generally considered superior in terms of coverage, sealing potential, and sound dampening. However, rolled insulation might be a more suitable choice if you’re looking for an easier DIY project or have a smaller budget. It’s essential to consult with a professional insulation contractor to determine the best option for your home based on your specific needs and requirements.

Attic Blown-in insulation can last for a long time, often up to 20-30 years or even longer, depending on the insulation material, installation quality, and environmental factors.

To ensure your attic blown-in insulation lasts as long as possible, it’s crucial to have it installed by a professional contractor who can guarantee proper coverage and sealing. Regularly inspect your attic for signs of moisture or pest damage, and address any issues promptly to prevent insulation deterioration.
