BEING FLOORED WITH FOAM! | Why Spray Foam Makes Sense Under Your Feet
Floors are one of the most overlooked parts of the building envelope — especially when space is tight.
Crawl spaces. Retrofits. Concrete floors. Low floor assemblies. Areas where you may only have a few inches to work with.
This is exactly where closed-cell spray foam can shine.
Unlike sheets of rigid insulation that have to be cut, fitted, joined and pieced together, spray foam is installed in place. It expands into the available space and bonds directly to the substrate, creating a continuous insulation layer without hundreds of cut edges and seams.
That means:
✅ No sheet-to-sheet seams
✅ Excellent air sealing
✅ Very low water absorption
✅ Bonded directly to the assembly
✅ High R-value in limited space
✅ No loose batts or pieces to shift or fall
✅ Far fewer pathways for bugs and rodents
✅ One continuous insulation system
And when you're insulating a floor, continuity matters.
Cold air doesn't care what R-value is printed on the insulation package if it can find its way around the insulation through gaps, joints and poorly fitted pieces.
Spray foam doesn't just sit in the floor assembly — it becomes part of it.
In this video, we're spraying several different floor configurations and showing why closed-cell foam can be such a powerful solution when you need maximum performance from limited space.
If you're building, renovating or trying to solve a chronically cold floor, don't just ask:
“How much insulation is underneath me?”
Ask:
“How continuous is it?”
Sometimes the best way to build a warmer floor is to get FLOORED WITH FOAM.
