Get the absolute best insulation for your home.

Whether your in Saint Louis, or Chesterfield spray foam will greatly improve the comfort inside your home while reducing your energy loss!

SPF insulation will help you save on energy costs and lowers utility bills by creating a tight seal and preventing air movement. The US Department of Energy (DOE) studies show that 40% of your home's energy is lost due to air infiltration. This air infiltrates the home in the form of drafts through walls sockets, windows and doorways. Spray foam expands and completely fills every tiny hole and crevasse providing a superior air seal combined with a powerful R-Value per inch of installed spray foam.

Bruce was very professional and knowledgeable. Answered all my questions. Josh was on time and did a good job spray foaming my garage attic. Reasonable priced. Would hire Koala again.

Melanie M.

Ray and his team were excellent, responsive and a great value. They took their time, and the spray foam insulation looks great in our cathedral ceiling. I can't recommend them enough and will use them again on the second half of our remodel.

Jacob N.

Better than excepted. Great job and they cleaned everything up. Plus, the new spray foam insulation is working great. Much Cooler and much quieter. The cost was reasonable. Great value for what they did.

LEARN ABOUT FOAM!

There are two types of spray foam insulation: Open Cell and Closed Cell. Both materials are great insulators and air barriers, and offer many benefits to make your Ballwin area home more energy- efficient. To determine which material is best for your project will require an evaluation by one of our highly qualified energy consultants.

SPF-Types

If you live in Saint Charles where there are extreme seasonal temperature changes or you live in a flood prone area, closed cell is often a better choice. Closed cell spray foam acts as a vapor barrier, keeping water and moisture out of your home and the foam itself is water resistant. Open cell is a great option if you live in a milder climate, as it is moisture permeable and help provides an optimal barrier. Often, regardless of where you live, you may choose to use both types of spray foam on a single project. Your Koala Insulation professional can help you decide which type of spray foam is best for you and your project!

When it comes to insulating your home, R-value matters.

R-value-matter

YES. Koala insulation of Gateway West - St Louis experts are trained in installing spray foam and take all precautions and follow strict guidelines during the application process. Once the material has been allowed to cure properly, there will be no harmful chemicals left behind. Fun fact - Koala Insulation of Gateway West - St Louis holds a certification from the American Chemistry Council for spray foam safety as well as appropriate insurance and licensure.

Spray foam should only be installed by a professional that has the proper training. The Koala Insulation spray foam material is mixed on-site in our fully self-contained rig and is sent through a hose into the stud cavity, where it hardens and creates a long-term barrier to guard against dust, noise, moisture and even rodent infestations.

Greater “racking” strength

Spray polyurethane foam has a higher racking strength, which adds structural strength and enhances overall building stability. In fact, spray foam is the only insulation material that adds structure integrity. It adheres to the cavities of the walls and in between ceiling joists making them more rigid to protect against cracking, shifting, or shaking during extreme weather conditions. NAHB Research demonstrated SPF filled walls could add from 75% to 200% racking strength to walls of OSB, plywood, light gauge metal, vinyl siding, or gypsum board.

Highly resistant during severe weather events

Not only does closed spray foam withstand the effects of high winds, but it also performs well under wet conditions. The material is water resistant, has minimal water absorption, and is classified as an acceptable flood resistant material. FEMA has published a rating system ranking building products from 1 to 5(not acceptable to highly acceptable). SPF carries a “5” rating for its outstanding water-resistant qualities.

Prevents bugs and rodents

Spray foam is effective at filling tiny cracks and gaps within walls and attic rafters. Rodents and insects such as rats, mice, cockroaches and other insects can enter through the tiniest of holes, leaving behind waste or destroying your attic storage. Koala spray foam insulation creates a durable barrier that seals all unseen entry points, making it an optimal insect and pest resistant option.

With the increasing demand for comfort and energy efficiency, spray foam is the optimal choice for your insulation needs. It can actually strengthen walls and has low vapor permeance (moisture transmission) and is ideal in rooms where sound-reduction is desired such as in home theaters or, for a light sleeper, bedrooms.

Koala technicians are trained in handling the spray foam components and in completing the installation safely.  We guarantee we will prepare the job site to meet all safety standards!

Koala Insulation Exceeded our Expectations

We became acquainted with Koala Insulation through Jennifer at the 2022 St. Charles Home Show last April. From the initial attic inspection to the day of installation, Jennifer was accessible, professional and very knowledgeable, answering all our questions.

Koala installed a solar attic fan and added blown-in insulation.

Mark, Cory and his crew and Jennifer arrived on time, worked efficiently and, the work area was cleaned up at the end of the project.

With hot weather upon us this early in the year, we’re enjoying a cooler attic which will save us money on our A/C bills. And the added insulation should reduce our heating bills, too.

I would recommend Koala to anyone wanting to lower their energy consumption and their bills; they have several options available.

These Guys Rock!

These guys ROCK! Not only was the estimate for adding insulation to my 58 year old house much lower than I had anticipated, they came out when the temperature broke a record for this day in May (93 degrees) and did an amazing job! Matt paid painstaking attention to the details that were vital (covering attic fan from inside, etc), and he and Corey (sp?) were professional, despite the heat."

2nd time using them....and once again extremely pleased of the work they performed. Wish more contractors had their competence and professionalism. Give them 5 out of 5 no problem.

Customer Review

Excellent service. Blown in insulations for two rooms. A big shout out to Jo for arranging it all so quickly, and to Josh and his mate for showing up on time, working quickly and getting the job done and the great clean up afterwards. It was not an easy job but they were pros and got it done. I have hired a lot of people to work on my homes over the years. I want people who show up when they say they will, quote me a fair price and stick with the price, do the work contracted and clean up after themselves. These folks more than checked the boxes on all accounts. I would highly recommend them

Customer Review

My house is newer, however had hardly any insulation in the garage. They did an awesome job from sealing where there was air leakage and canned light covers. The fiber glass blow in was quick and they cleaned up as if they were never there. I highly recommend this team and look forward to having them do my home attic very soon!

Customer Review

WOW!!! From the free quote, to install, to clean up, these guys are FANTASTIC! In a world full of horror stories on getting work done on your house, these guys are a knight in shining armor. Customer service is very responsive in text, email and phone calls to set up appts etc. We had insulation installed in our finished garage, in the ceiling (there is a bedroom above the garage). I was worried it would be a terrible mess and that it wouldn't work as well as I wanted it to, to regulate temperature. The installers left my garage cleaner than when they came and more importantly that bedroom is now staying within 1-3 degrees of the thermostat (previously a 4-8 degree difference). Highly recommend."

Customer Review

We decided last minute to remove the insulation on our renovation project. Jennifer was absolutely wonderful! She worked it out so they could do the work before we pulled down the ceilings. The crew showed up on time, were very nice, did a great job removing the insulation, and the price was honored based on a sight unseen quote. We highly recommend Koala Insulation.

Review by Orville

Project: Install or Upgrade Blown-In Insulation
Comments: It was smooth from the first contact (owners) the sales rep that gave a thorough description of material products to choose from (what was most suitable for our need and application options. We were impressed and confident enough to sign up for the job, without other quotes. A few days later, a father and son team showed up the job which was completed in about 2.5 hours, including clean up. We didn't bother with seeking other estimates and have no regrets. Orville
