Injection Foam Insulation
Injection foam insulation consists of aqueous resin solutions mixed with foaming catalysts and compressed air in order to form a new kind of insulation substance with a texture and consistency very similar to that of shaving cream.
The resulting insulating material will then be injected into wall cavities. As it dries, the foam will harden to effectively create a layer of insulation in the walls.
Injection foam insulation is easily one of the most economical as well as efficient options for insulating buildings, and without risking damaging the walls or having to remove existing paneling, drywall, or other wall sections.
You’ll be able to use injection foam insulation for shingles, blocks, vinyl siding, bricks,, aluminum siding, and stucco.
Additional benefits of injection foam insulation includes its higher R (resistance) value, quick installation, noise reduction, drastically improved indoor air quality, environmental friendliness, and hire smoke and fire ratings.
Most of the time, injection foam insulation is used in enclosed cavities of existing walls. While this may sound like that it would create a massive mess in your home or commercial building, the truth is that usually just the opposite is true. As a result, you will not need to tear down any existing drywall.
Other types of old insulation in walls, such as fiberglass, will not need to be removed from walls either before installation takes place. The only type of insulation that will be of a little concern to the professionals here at San Antonio Spray Foam will be cellulose, and our crews will work to remove as much of it as possible before we inject the foam.
There will also be different processes for the different kinds of homes that we work with. Examples include homes that have aluminum or vinyl siding…we will require a piece of the siding to be removed from the home, so holes can be drilled into each of the stud cavities. The injection foam will then be run through a hose with a nozzle. We will place the nozzle in the drilled hole so the foam can pump into each cavity. We will then further fill in each hole with Styrofoam plug.
Another example of where the processes will be slightly different are when we are working with brick homes. Small holes will need to be drilled into the mortar joints in between each of the studs, allowing the foam to then be injected later. When each cavity is filled up with insulation, the holes will then be re-mortared to match the mortar that is already there.
Finally, in the case of wood siding, we will follow the same process for aluminum and vinyl, and then fill each hole with wooden plugs once the foam has been injected.
