Benefits Of Wall Insulation

Energy Efficiency
Insulated walls reduce heat loss, helping lower energy bills
Improved Comfort
Insulated walls help keep indoor rooms warmer in winter and cooler in summer, creating a more comfortable living environment year-round
Noise Reduction
Block out unwanted outdoor and room-to-room noise.
Moisture Control
Helps prevent moisture buildup within walls, reducing the risk of mold and mildew.

Make drafty rooms and high monthly energy bills a thing of the past with enhanced wall insulation — no major remodeling required.

Wall Insulation Gives You Comfort At Home

Many homes, especially older ones, have uninsulated or under-insulated walls. This puts homeowners in a challenging position — do they endure unregulated temperatures and high energy costs or pay for a renovation?

Luckily, you don’t have to choose between two difficult options. Koala Insulation uses specialized techniques to insulate existing walls without tearing down drywall, resulting in better comfort and energy savings without a complete remodel. It’s a win-win!

The Benefits of Excellent Wall Insulation

Insulating walls in your home can bring you:

  1. Improved Indoor Temperature Stability: Insulation keeps outdoor air where it belongs — outside. The temperature-regulated indoor air will keep everyone in the house more comfortable. 
  2. Reduced Drafts and Cold Spots: New insulation fills the gaps and cushions you against cold weather, getting rid of those frustrating drafts throughout your house. 
  3. Lower Energy Bills: Your heating and air conditioning won’t have to turn on as often to keep your home at your desired temperature, costing you less.
  4. Pest and Sound Resistance: Insulation is a physical barrier between your interior living spaces and the outside world, so it can also keep pests and noise out.
  5. Increased Home Value and Year-Round Comfort: While not visible to you, wall insulation vastly improves your home. You’ll notice the improved temperature regulation immediately, and your cost savings long term. Plus, when it comes time to resell your home, buyers will pay more for a house they know they’ll live safely and comfortably in.

Wall Insulation Detailed Service Breakdown

Koala Insulation offers premium solutions and support at every step of the wall insulation process. Find out how our wall insulation services combine easy and efficient processes with innovative materials and techniques.

Wall Cavity Inspection

Our experts will identify which walls are suitable for retrofitting.

Drill & Fill Insulation Process

In this practical wall insulation process, three-inch holes are drilled in each stud bay, and dense-pack cellulose is blown in. Get new insulation without a complete tear-down and renovation.

Interior vs. Exterior Access

Interior wall insulation involves drilling through the drywall, which will be patched after. The other option is to remove siding to access our work area from the outside.

Why Cellulose?

Blown-in cellulose is pest-resistant, effective, and environmentally friendly. Its loose-fill nature means it easily fills in every corner and seam. 

What We Don’t Offer

Please note that we don’t install injection or open-cell spray foam into finished walls to avoid damaging them.
