Foam it Green Open Cell DropFill System™

If you have closed walls in your residential or commercial property that are in need of insulation, you can take advantage of our revolutionary DropFill System™. Insulating closed walls with existing fiberglass can be a large undertaking, costing you time and money that you could be using on other aspects of your property, or anything else! With the DropFill System™, you can avoid hiring expensive contractors who will destroy your walls in order to remove the existing fiberglass. You don’t need any prior knowledge or experience to use this system, and our team is here to offer you support 24 hours a day, 7 days a week. Below, we have outlined simple instructions regarding how to use the DropFill System™, and of course we are always here to answer your questions if you need any additional information.

Insulate Existing Walls Containing Fiberglass

Until now, insulating closed walls meant tearing out the drywall to add spray foam, or having a company drill unsightly holes through the outside of your home.

Now, the DropFill System™ makes it easy to add spray foam insulation to existing walls that already contain fiberglass.

One-Hole Under-Baseboard Installation

  • No expensive contractors tearing your walls apart
  • No expertise required, designed for first time users
  • No removal of existing fiberglass means big savings

Uses Proven Foam it Green Solutions:

  • Yellow + Blue = Green system makes installing simple
  • 24×7 support – we’re always standing by for you
  • Unique Class 1 fire retardant & anti-microbial formula

How Easy Is It? Here are the Steps:

spray foam insulation for existing walls wallsrevStep 1:
Remove, and then drill one 2” hole per bay under, the baseboard (or above it if you prefer).

Step 2:
Feed the patent-pending DropFill System™ up the first cavity BEHIND the fiberglass, trying to keep it as centered as you can.

While foam will spread to fill the space allotted, it is ideal to fill from as close to the center as possible.

Step 3:
You’re ready to start filling your first cavity! This product is uniquely designed to fill the cavity (already containing fiberglass) correctly if you follow the easy metering system in the instructions.

Pull the trigger. Follow the unique metering system that comes with your DropFill System.™ Then, remove the system from the wall and pop the nozzle off the gun.

That’s it!

vertical-dropfillNote: There are always minimal risks that come with this type of project, regardless of type of foam or company. If you don’t follow the easy metering system, or if your walls are previously damaged or contain fillers other than fiberglass, there is a chance that you may not fill the cavity fully, or that a blockage could occur, pushing out or damaging the drywall or plaster.

If you have concerns that your fiberglass may be compromised (wet or moldy due to previous leaks for instance), you may want to remove a larger section of drywall and inspect it before deciding which method of spray foam to use. If your fiberglass needs to be removed, then you’ll want to use our Slow Rise System instead. Slow rise is intended to fill an empty wall cavity. The DropFill System™ is specifically designed for walls that do contain fiberglass.
