As an expert in the field of insulation, I have seen many homeowners struggle with the decision of whether to use blown or rolled insulation. Both options have their pros and cons, and it ultimately depends on your specific needs and preferences. However, after years of experience, I can confidently say that for most homes, blown insulation is the better investment. Let's start by understanding the difference between blown and rolled insulation. Blown insulation is typically made of cellulose, fiberglass, and minerals or wool.
This combination results in an R-value of 3.2 to 3.8, which is slightly lower than that of rolled fiberglass insulation. However, blown insulation is designed to cover large areas quickly and efficiently, making it a popular choice for attics and interior walls. On the other hand, rolled insulation is usually made of plastic and has a higher R-value. It comes in the form of long rolls that can be easily cut and installed between beams and wall studs. While it may be more effective in terms of preventing heat flow, it is not as efficient when it comes to installation. One of the main advantages of blown insulation is its eco-friendliness.
Manufacturers use recycled materials such as newspapers and slag wool to create this type of insulation, reducing its carbon footprint. Additionally, blown insulation is not suitable for DIY projects, which means that a certified attic specialist will take care of everything for you. This results in a quicker and more efficient installation process. However, one downside to blown insulation is that it can be harder to replace if compromised by moisture, mold, or pests. Rolled insulation, on the other hand, is easier to remove and replace if necessary.
So if you live in an area prone to these issues, rolled insulation may be a better option for you. When it comes to reinsulation projects, blown insulation is often the preferred choice. This is because it can easily fill in gaps and crevices, providing better coverage and preventing heat loss. Rolled insulation, on the other hand, may leave some areas exposed if not installed properly.
Now, let's talk about the installation process for each type of insulation.
Blown fiberglass insulation requires the expertise of professional attic specialists, as it is susceptible to mold if not properly sealed. The three types of fiberglass insulation are blown insulation, rolled insulation, and block-shaped insulation.Blown insulation is installed using a blowing machine to inject loose insulation into the space being insulated, usually an attic or interior wall. This method ensures that every nook and cranny is filled with insulation, providing maximum coverage. Rolled insulation, on the other hand, is installed by cutting pieces from a larger roll and placing them between beams and wall studs on the attic floor. This can be a time-consuming and physically demanding process, especially for larger attics. However, rolled insulation is a great option for DIY projects as it does not require any special equipment. So which one should you choose? As I mentioned earlier, it ultimately depends on your specific needs and preferences.
If you want a quick and efficient installation process, blown insulation is the way to go. But if you live in an area prone to moisture or pests, rolled insulation may be a better option. In conclusion, both blown and rolled insulation have their advantages and disadvantages. As an expert in the field, I highly recommend blown insulation for most homes due to its eco-friendliness and efficiency. However, it's always best to consult with a professional before making a decision to ensure that you choose the right type of insulation for your home.
