Get the absolute best insulation for your home.

Whether your in Arnold, or Florissant 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.

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.

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 Festus 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 St. Louis 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!

YES. Koala insulation of 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 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!

They did an amazing job!

They did an amazing job! Super fast and very professional. Cleaned up afterwards. I had my attic space insulated and a solar fan installed.

High Ridge, MO

We noticed a difference immediately

The folks from Koala did a great job! After looking at the insulation in our attic and seeing some low (and even bare) spots, we had Koala come out and give us an estimate. They took a look and gave us a number of options and explained each one thoroughly. We scheduled them to come back out and they got everything wrapped ** in a few hours. Showed us pictures of the less accessible areas of the attic and then I climbed up and took a look around the access hatch. Looks great and we noticed a difference immediately since it got near triple digits outside that afternoon. From estimate to installation we were completely satisfied with the entire process!

Thanks to Koala Insulation we can actually use our second floor!

Every part of the process was smooth and professional. Arrived on time, immediately identifying our problem and laying out all options. Jon provided an estimate and explained the tax credits. Nick's team showed up promptly; they were clean, courteous and efficient. The price was reasonable, and the results were immediate. Our second floor went from 85 in 95 degree weather, to a cool 72 in the same heat.""

HIGHLY recommend them

They were incredibly detail oriented and went above and beyond and repaired multiple air vents that were previously damaged. After the install, they went through my entire house to vacuum to make sure it was spotless by the time they left. I HIGHLY recommend them. They were on time, efficient, and did a great job. Cannot say enough good things about my experience.

My Upstairs is Cool Again!!!

My Upstairs is Cool Again!!! The Koala Crew is very professional. They bring in their on blankets/carpets to place on your floors & steps so the don't dirty your house. The process of installing more installation went much faster than I thought it would. They cleaned up after themselves. Then within a few hours after they left with the help of my AC, the upstairs no longer felt humid. It was awesome. I knew we made the right decision to go with Koala.
