Fill Gaps and Quiet Noise in Existing Walls

Blown-in cellulose insulation for attics and enclosed wall cavities in Lawton, Oklahoma.

If your older home in Lawton has thin or missing insulation and you want to improve comfort without tearing open walls, blown cellulose offers dense coverage that settles into every gap and reduces both heat transfer and sound transmission. Cellulose is made from recycled paper treated with fire retardant, and it installs through small access holes drilled into wall cavities or directly onto attic floors using a blower hose.

Superior Thermal Solutions LLC uses professional equipment to blow cellulose at the correct density for your application. In attics, we spread the material evenly over joists to reach the recommended depth for your climate. In walls, we fill each stud bay from top to bottom, checking with a density gauge to confirm proper packing. Cellulose resists air movement better than fiberglass because its smaller fibers interlock, creating a denser barrier that slows convective heat loss and blocks outside noise.

How Cellulose Installation Works in Practice

When we install cellulose in your Lawton home, we bring a trailer-mounted blower and bags of cellulose that we feed into the machine. For attics, we direct the hose across the floor and build up layers until we reach the target depth, taking care to cover all joist bays and corners. For walls, we drill small holes near the top of each stud bay, insert the hose, and fill from the top down, monitoring the hose for resistance that signals the cavity is full.

After installation, you will notice that rooms stay warmer in winter and cooler in summer because cellulose slows the movement of air through your walls and ceiling. You will also hear less traffic noise and neighborhood sound coming through exterior walls. The dense packing reduces drafts around outlets and baseboards, making your heating and cooling system work less to maintain set temperatures.

Cellulose does settle slightly over the first year, so we add extra material during installation to account for that natural compaction. The fire retardant treatment prevents the material from supporting flames, and cellulose does not provide food for insects or rodents. We patch access holes in walls with drywall plugs and touch up paint to match your existing finish, leaving minimal evidence of the installation.

What Homeowners Typically Want to Know

Before choosing cellulose, most people ask us how it compares to other insulation materials, whether it attracts pests, and how we install it without making a mess inside the house.

What makes cellulose different from fiberglass?
Cellulose is denser than fiberglass and resists airflow more effectively, which reduces convective heat loss. It also dampens sound better and is made from recycled content, making it a good choice if you prefer environmentally friendly materials.
How do you install cellulose in closed walls?
We drill access holes near the top of each stud bay, insert a fill tube, and blow cellulose from top to bottom until the cavity is packed to the correct density. After filling, we plug the holes and touch up the paint to match your wall finish.
When should I choose cellulose over other insulation types?
You should consider cellulose when you need to insulate existing walls without major remodeling or when you want better sound dampening along with thermal resistance. It works especially well in older homes in Lawton that were built with minimal or no wall insulation.
Why is cellulose treated with fire retardant?
Cellulose is made from paper, which burns easily without treatment. The fire retardant slows ignition and flame spread, allowing the material to meet building code requirements for insulation safety.
What areas of my home can receive cellulose insulation?
We blow cellulose into attics and enclosed wall cavities. It works in both exterior and interior walls, and we sometimes use it in floors over unheated crawl spaces when access allows.

Cellulose insulation has been used in homes throughout Lawton for decades because it adapts to irregular framing and delivers consistent thermal and acoustic performance without requiring you to open walls or ceilings.
