As a home insulation expert, I have witnessed firsthand the impact that different types of insulation can have on a home's comfort and energy efficiency. While all forms of insulation have their pros and cons, I firmly believe that blown-in insulation is the top choice for most homeowners. Not only is it cost-effective and eco-friendly, but it also offers easy installation, especially in hard-to-reach areas like inside walls and sealed attics. In this article, I will explore the benefits of blown-in insulation and help you determine if it's worth investing in for your home.
One of the main reasons why blown-in insulation is worth the money is because it can significantly improve a home's energy efficiency. Heat is primarily lost through the roof, so insulating the attic with blown-in insulation can help retain heat inside the house, making the living space more comfortable and reducing energy bills during the winter months. This is especially crucial for older homes that may have inadequate insulation due to outdated building codes. But what exactly is blown-in insulation? It consists of small pieces of material, such as confetti, that are inserted into walls and attics through a long hose.
This allows for easy installation in existing homes without the need for tearing down drywall or other messy and time-consuming processes. Additionally, blown-in insulation can also seal small gaps and spaces as it settles, providing better coverage and reducing sound transfer between outside and inside. To install blown-in insulation in existing walls, holes are drilled in the top of each space between studs (usually from the outside) and the material is blown through a long, flexible hose. The hole is then sealed with a plug that matches the coating, although these plugs may be visible if the coating is brick or stucco.
One potential disadvantage of blown-in insulation for walls is that obstructions in the wall space, such as drain pipes or outlet boxes, can prevent the insulation from filling the entire space, leaving gaps without insulation. There are three main types of blown-in insulation: loosely filled fiberglass, cellulose, and rock wool. Each has its own advantages and disadvantages, but all can significantly improve a home's energy efficiency. The recommended minimum insulation values vary by geographic area, so it's important to research the recommended values for your region before making a decision.
When it comes to installation, you'll need a fan to distribute the insulation evenly. Some stores may lend you a blower for free if you purchase a certain amount of insulation bags. While it may be tempting to try and install blown-in insulation yourself, it's best to leave wall insulation to the professionals due to potential hazards like electrical cables and pipes. However, installing blown-in insulation in an attic can be a DIY project as long as you follow safety precautions and carefully read the instructions on each insulation bag and fan.
One common question homeowners have is whether blown-in insulation will ever need to be replaced. Generally speaking, blown-in insulation can last from 20 years up to the lifespan of a home. Fiberglass insulation typically lasts between 80-100 years, while rock wool can last up to 100 years due to its resistance to moisture. Cellulose, on the other hand, may need to be replaced every 20-30 years due to its recycled composition and lower moisture resistance.
In conclusion, blown-in insulation is definitely worth the investment for most homeowners. Not only does it offer significant energy savings and improved comfort, but it also has a long lifespan and is environmentally friendly. If you're considering adding insulation to your home, I highly recommend looking into blown-in options and consulting with a professional for installation.
