Advantages Of The Drill And Fill Spray Foam Installation Process

Drill and fill insulation installation is a method of installing spray foam insulation in a home that offers many advantages over other installation methods. It is the most common method of installing spray foam insulation into a home. It is a closed-wall installation procedure that can be completed throughout an entire home in 24 hours or less

The following are the five major advantage of the drill and fill installation process: 

The speed of the process

Installing batt or rigid board insulation requires more parts of a wall to be removed and disrupted. This means that it will generally take longer than drill and fill installation. When installing spray foam insulation into wall cavities, contractors can sometimes even complete the installation process—minus the time it takes to allow the new insulation to cure—in only two hours

Cost savings

Because the drill and fill insulation installation procedure is the quickest and simplest of all insulation installation procedures, it costs the least amount of money in terms of labor.

It also tends to save homeowners money over time on their energy bills. Spray foam insulation fits perfectly into even hard to fill spaces in a home's walls. Some spray foam insulation manufacturers claim that their spray foam can save homeowners up to 50 percent on their heating and cooling bills. 


The drill and fill installation procedure is the least invasive of all procedures for installing insulation. It requires only that holes be drilled into a home's walls so that foam insulation can be sprayed inside.

This means that it is the perfect option for adding insulation to an existing home without having to deconstruct walls. The non-invasiveness of the procedure makes it less likely that the home's residents will be inconvenienced or subject to any safety hazards during and after installation. 


Spray foam insulation installed with the drill and fill procedure will be completely invisible from both the interior and the exterior of a home. Not only are drill holes filled in after the insulation is installed, but the holes are then covered with a siding material or another wall covering so that they leave no visible marks. 


Closed spray foam insulation in particular is one of the insulation options with the highest R-values. This means that it is one of the most effective options for keeping a home's interior temperatures under control. Closed spray foam insulation has an R-value of 6.5
