Are you currently looking for the best type of insulation for your home? Well, you came to the right place. In our previous blog post, we discussed the importance of insulation and how it plays a crucial role in keeping our homes comfortable and energy-efficient. We covered various types of insulation that are commonly used in residential and commercial buildings. Today, we’re excited to focus on one of the most popular and effective insulation choices out there: R19 insulation.

R19 insulation has gained immense popularity among homeowners due to its remarkable thermal resistance and ease of installation. If you’re looking to enhance your home’s insulation and reduce energy costs, R19 insulation might just be the perfect fit for you. So, let’s dive into this comprehensive guide to understanding and using R19 insulation to transform your living space into a cozy haven.

What is R19 Unfaced Insulation?

Before we get into the nitty-gritty, let’s understand what R19 unfaced insulation actually is. Let’s break it down into two parts.

R19 refers to the insulation’s thermal resistance commonly known as the R-value. As we previously covered, R-value is a measure of how effective the insulation is at resisting the transfer of heat. The higher the R-value, the better your insulation’s performance will be. R19 insulation simply means its R-value is 19. 

Unfaced insulation is the type of plain insulation roll or batt without facing. Unfaced insulation, as the name suggests, lacks a vapor barrier or facing material on either side. 

Why Should You Choose Unfaced Insulation?

This type of insulation does not have the added protection of a vapor barrier, so as a homeowner, you might think, why would I choose this roofing insulation? 

The truth is that in places such as Owasso, moisture is not as big a problem as in other states.

This makes it an excellent choice for specific applications. It’s also ideal for spaces such as interior walls, ceilings, and floors, where moisture control is not necessary. 

Plus, unfaced insulation is usually more cost-effective, making it a budget-friendly option.    

The Benefits of Unfaced R19 Insulation

R19 unfaced insulation comes with a range of benefits that make it a popular choice for homeowners. Some of the key advantages include:

1. Versatility

One of the major benefits of R19 unfaced insulation is its versatility. You can use it in many parts of your home, including attics, crawl spaces, and between studs in walls. It fits snugly into most spaces, ensuring maximum thermal efficiency.

2. Environmentally Friendly

Unfaced insulation is often made from eco-friendly materials like fiberglass or mineral wool. These materials are non-toxic and safe for indoor use, promoting a healthier living environment for you and your family.

3. Easy Installation

Installing R19 unfaced insulation is a breeze! You can do it yourself with minimal tools and equipment. It’s an excellent DIY project that saves you money on professional installation costs.

4. Energy Savings

By effectively insulating your home with R19 unfaced insulation, you’ll reduce heat transfer and minimize energy loss. This means lower energy bills and a more comfortable living space all year round.

5. Sound Proofing 

Unfaced roof insulation is great when it comes to soundproofing. In addition to its thermal insulation capabilities, R19 unfaced insulation also offers soundproofing benefits. It can help dampen noise transmission, making your home quieter and more peaceful.

How to Install R19 Unfaced Insulation

Installing R19 unfaced insulation is not rocket science, and you can handle it like a pro with these simple steps:

Gather the Materials

First, ensure your safety and gather all the necessary materials. This will include the following things: 

  • Insulation batts or rolls
  • Utility knife
  • Safety goggles
  • Dust mask

Measure and Cut

Measure the space where you plan to install the insulation and cut the batts accordingly using a utility knife.

Fit the Insulation

Carefully fit the insulation into the desired area, ensuring it fills all gaps and voids. If you are installing it as roof insulation, firmly place the batts in between the joists. 

Additional Tips

Remember to leave some clearance around recessed lighting fixtures and avoid compressing the insulation, as it reduces its effectiveness.

Once you’ve installed R19 unfaced insulation, it’s essential to maintain it properly to ensure its long-term effectiveness:

Regular Inspection

Perform regular inspections to check for any signs of damage, moisture, or mold growth. Promptly address any issues you find.

Moisture Control

Although R19 unfaced insulation doesn’t have a vapor barrier, it’s essential to address any moisture issues in your home to prevent damage to the insulation and other building components.

Sealing Air Leaks

Sealing air leaks around doors, windows, and other openings will help maintain the insulation’s thermal efficiency and reduce energy waste.

Why Should You Call A Professional?

While installing R19 unfaced insulation may seem like a straightforward DIY task, it is always recommended to call a professional.

For large-scale insulation projects, like insulating an entire attic or crawlspace, hiring a professional can ensure the job gets done efficiently and accurately.
