How To Insulate a Wall Without Removing the Drywall: Steps by the Pros

Wall with insulation installed

When many people think of home insulation, they imagine rolls of insulation between the beams of a house. As such, it might seem impossible to install insulation for an exterior wall of the house without having to cut away the drywall.

Fortunately, if you know how to insulate a wall without removing the drywall, you can save time and money on your insulation project. Anthem Insulation & Home ranks among the best-known and most trusted wall and floor insulation contractors in Woodstock, GA. They know the professional secrets to effective, stable insulation without having to redo drywall.

Don’t feel like you have to ruin your interior design by ripping down your walls and covering furniture in dust and debris. Don’t put off installing quality insulation and wind up paying skyrocketing bills this winter. Protect yourself by learning how to insulate a wall without removing the drywall.

Choosing the Right Insulation

Homeowners can insulate their homes in many ways, using many different types of insulation. Using the right insulation and the proper professional insulation technique allows you to protect your home from the cold without tearing down and rebuilding walls. 

Spray Foam Insulation

Spray and foam insulation can be more convenient if you already have drywall in place because you only need a small opening to insert the drywall.

Roll / Batt Insulation

Roll and batt insulation are two types of insulation you can apply to your walls. Roll insulation consists of long sheets that you can cut to the height of your walls, while batt consists of squares of insulation. Both types of insulation take up space, so they prove more of a challenge to apply to a wall once the drywall is in place.

Insulating Ground Floor Exterior Walls

The easiest way to install insulation on an exterior wall at the ground floor level of a home without going through the drywall involves removing some of the exterior siding and applying foam insulation behind the drywall. Cover the opening with a tarp to prevent rainwater or debris from getting to the insulation during the job. 

Adding insulation to a second-story wall through the house’s exterior adds some difficulty because you will be working off the ground.  

Insulating Finished Attics

Even though many homeowners often leave attics unfinished, they still may need to improve the insulation in their attics after installing the drywall. Perhaps a previous owner installed the drywall and forgot to put in enough insulation. Even so, the problem proves easy to fix with some patience.

Eventually, your roof will need repair or replacement. When it does, add foam insulation, roll, or batt insulation after you or your contractor has torn off the roof. If you don’t want to wait, you could make a small opening in the roof and add foam insulation. However, it might be more difficult than drilling openings in the drywall and patching them up.

Insulating Finished Basements

The best way to install insulation is before you finish the basement and install drywall. However, with an already-finished basement, you can still add insulation without damaging the drywall.

It might seem like a puzzle learning how to insulate a wall without removing the drywall if you can’t get to it from the outside. Your best option might be to gain access to the space from above and add spray foam insulation.

Insulate Other Parts of the House

Knowing how to insulate a wall without removing the drywall also means recognizing other ways that heat can leave your home. You can improve your home’s ability to retain heat by insulating other areas as well, such as:

  • Pipes
  • HVAC ducts
  • Windows
  • Doors

If you slow down the loss of heat from your home by sealing off other avenues of escape, you might be able to bring heating costs down without having to fix the insulation in your walls at all.

Hanging decorative materials such as carpeting or tapestries on the wall will reduce heat loss as well. It also works to add curtains and some other window treatments.

Injection Foam vs. Spray Foam Insulation: What Are the Differences?

Many homeowners ask us the difference between injection foam vs. spray foam. Generally, injection foam does not expand, whereas spray foam expands depending on the open or closed-cell structure. If you’re looking to install or replace insulation in your home, work with the top insulation contractor in Cumming, GA

Injection Foam vs. Spray Foam Insulation

Below are the three main differences between injection and spray foam insulation.

1. Installation Method

Injection Foam

Injection foam installation involves injecting foam into walls, roof cavities, and closed spaces. As a significant benefit, existing walls don’t need demolishing before installation. Additionally, injection foam takes less time to prepare than spray foam.

Contractors use injection foam, known as ArmorFoam, to insulate enclosed spaces. Injection foam insulation’s texture is similar to shaving cream. Before application, injection foam must undergo the mixing of a foaming agent, water, and resin.

Injection foam does not require removing the old or existing insulation. However, the contractor may remove cellulose insulation from the walls before installing it. As a result, the injection foam will fill and spread through the entire surface. 

Spray Foam

Spray foam insulation consists of chemicals derived from petroleum extracts. The foam combines two liquids, resulting in a chemical reaction to create polyurethane foam. Professionals can install spray foam insulation in open cavities, including walls, crawl spaces, and attics.

Before applying spray foam, the contractor will remove all the old fiberglass and cellulose. Spray foam adheres well to clean surfaces and fills spaces more consistently. With spray foam insulation, you can fill every gap and crevice.

Spray foam requires more preparation time than injection foam because the contractors have to move the furniture and other household items. Then, a plastic sheet or wrap covers the flooring to prevent spray foam from getting on them.

2. Air Sealing and R-Value

R-value and air sealing are crucial factors when comparing injection foam vs. spray foam.

Both injection foam and spray foam insulation create an air seal but have different R-values. Air leaks can increase your heating and cooling bills by up to 30%.

R-value indicates how well the insulation performs, so a higher value means better insulation. Although the R-value is important, it’s not the only deciding factor.

Injection foam insulation achieves an insulation rating of R-18, depending on the cavity size. In comparison, the R-value for open-cell spray foam falls between 3.6 to 3.9 per inch. The closed-cell spray foam has an R-value of 6 and 7.

3. Open-Cell vs. Closed-Cell Foam

Injection foam consists of an open-cell structure that will not expand. In contrast, spray foam has open and closed-cell types. Injection foam works best with enclosed and existing walls, whereas spray foam is better for open walls and crawl spaces.

Unlike open-cell foam, which remains lightweight, closed-cell tends to stay stiff and dense. Since open-cell insulation can move with the foundation of the house, it’s better suited for homes. A closed-cell structure works better on pole barns with exposed walls.

Can You Over-Insulate a House?

Many homeowners struggle to get enough insulation for their homes, but can you over-insulate a house? 

Professionals don’t hear this question too often. Still, knowing the answer may positively impact your next renovation or construction project.

Attic insulation contractors in Buckhead explain what you need to know about home insulation.

What to Know When Insulating Homes in Buckhead

Home insulation is an effective tool for saving money on energy costs. These materials will impact your energy efficiency when warming and cooling the property. Unfortunately, many homeowners are unsure how much insulation they need for their space.

Insulation materials help slow down heat moving toward cold places. It will never stop heat, but it can be an effective tool for slowing it down.

Protect Your Energy Savings

So, how much insulation is too much? The answer may surprise you. Most professionals agree that adding insulation is effective up to a point.

For example, adding an inch of insulation to a home with little insulation may significantly improve indoor temperature control. However, adding an inch of insulation to a house with a large volume of insulation is simply a waste of money.

If you are unsure how much of this material you need, hire a contractor. These professionals have the tools to accurately measure and install the right amount of insulation for the property.

The Attic

Can you over-insulate a home with a large attic space?

Heat will always travel upward. This principle suggests that the majority of the heat in the home will make its way to the attic. When investing in attic insulation, you can save up to 50% on your heating bills

Don’t overdo it during your installation, however. Remember that adding too much insulation in the attic may cost you more than you save. Excessive weight could also compromise the integrity of your roof.

The Walls

Wall insulation is essential for home temperature control. However, if you stuff your walls with too much insulation, the product will reduce indoor air quality. Insulation consists of wool, fiberglass, and other materials that are dangerous to your health.

Overexposure to these particles in the air may cause:

  • Eye and throat irritation
  • Aggravated symptoms of bronchitis and asthma
  • Persistent headaches 
  • Fever
  • Nausea 
  • Internal bleeding

Keep your family safe by avoiding insulation overuse and always use the proper protective gear when handling insulation.

The Environment

An appropriate volume of home insulation is also a great way to protect the environment. You can reduce the energy you consume when keeping the home well insulated. 

However, too much of a good thing can be harmful. Manufacturing insulation produces chemicals that negatively impact the atmosphere. Using the appropriate insulation for your home will reduce your carbon footprint and contribute to a clean environment.

Reasons Why Air Sealing an Attic Can Lead to Better Insulation

Even with the appropriate insulation in your attic, air can seep between small gaps in the attic floor, warming the air in your home that you want to keep cool or chilling air that you want to stay warm. The experts from Anthem Insulation & Home attic insulation service in Alpharetta describe how air sealing an attic can help you maintain your home temperature and save energy.

What is Air Sealing?

Air sealing an attic involves testing for drafts in the attic space, including the attic floor, crawl spaces, and sub-roof areas. Depending on where inspectors find the drafts and the formation of the leak, technicians will use caulk or other sealants to block airflow between your attic and living space.

Your home should maintain a similar temperature to where you set your air conditioning or heating system. Sealing the attic floor prevents heat transfer through small gaps between your living space and your attic, as well as between the attic and outside.

How Do Attic Insulation and Air Sealing Work Together?

Whether your attic insulation uses foam board or fiberglass insulation, the primary purpose of insulation is to keep cool air on one side and warm air on the other. During the summer, you want cool air inside and hot air to stay outside. You want to keep your home warm in the winter to fight off outside chills.

You can maintain your home’s temperature year-round by air sealing an attic and ensuring there is enough insulation in place. Simply air sealing without insulation won’t offer your home enough protection against the sun heating the attic through the roof in the summer or from the cold wind gusts that can enter a home through the attic in winter.

Appropriate attic insulation can help keep heat, cold, and moisture out of your attic space. Roofs have to breathe through the attic space to expand and contract with changing temperatures. Air sealing can further impede heat transfer through the attic between your home and the outside.

Are There Risks to Air Sealing?

Some homes feature construction where some systems vent into the attic, such as chimneys or furnaces. These systems produce fumes that can be harmful to inhale, especially carbon monoxide.

Never attempt to air seal an attic yourself. Always hire a professional air sealing and insulation company to inspect your attic and any systems that utilize the attic space. An experienced attic insulation company inspector can advise you about whether it would be safe to seal your attic.

Can Air Sealing Save Me Money on My Energy Bills?

Air sealing can typically save you between 10-30% on energy bills, depending on several other factors. On average, 43% of your energy bill comes from heating and cooling according to Energy Star.

Other factors that can affect heating and cooling costs include:

  • Home insulation in walls
  • HVAC capacity rating
  • Seasonal Energy Efficiency Ratio (SEER) of your air conditioning system
  • Secure duct sealing
