How to Insulate a Garage Floor

Choosing to finish out your garage for additional space is a practical and ambitious decision. One of the primary steps in this project will be insulation. If you’re unsure of how to insulate a garage floor for maximum comfort and thermal stability, choose InSoFast insulation panels for their straightforward installation, high-quality insulation power, and resistance to moisture penetration.

InSoFast insulation panels meet all existing and future energy regulations, and they apply effortlessly to all flat surfaces, including ceilings, walls, and floors.

How to Insulate a Garage Floor

The insulation panels produced by InSoFast, LLC, outperform competing fiberglass insulation with higher R-values, and they make wiring, drywalling, and their installation quite simple.

The floor of your garage is cold, and a layer of InSoFast insulation panels will correct this problem. We offer two product lines that are suitable for interior use.

The base-level insulation panel, 2.0 Flat Panel, provides R-8.5 resistance to thermal energy loss, and it outperforms fiberglass insulation with R-13 strength. Each panel measures 2’x4’ with a 2” depth. Made of closed-cell EPS foam, these panels are non-toxic and physically and chemically stable. With a fire-resistant feature, a Class III vapor barrier, and an insulation layer, the systems made from our panels fulfill a range of needs.

Other features included within the panels:

  • Built-in, rot-resistant framing
  • Moisture control channels
  • Service raceways
  • Straightforward and stackable panel design

InSoFast insulation panels are physically and chemically inert, so you’ll be able to rely on them to perform well without breaking down or releasing toxins.

InSoFast closed-cell EPS foam provides long-term presence and thermal stability while facilitating DIY installation and cost-effectiveness.

Single-person or small crew installation will be far easier with InSoFast insulation panels. They weigh little and fit together intuitively without requiring taping. Making mistakes during installation is highly unlikely. You can install these panels on the floor in four different ways, including the following:

  • Floating Installation – In a running bond pattern, piece the panels together using the tongue-and-groove notched alignment edges without any adhesive implements.
  • Glue Down Installation – With this method, you’ll use Loctite PL 3X Stronger Construction Adhesive along the stud to adhere the panels to the floor.
  • Screw Down Installation – With concrete screws through the studs, this method securely attaches panels to the concrete floor.
  • Fully Adhered Installation – Blend application with the recommended construction adhesive, and for tile applications, set them in compatible thin-set tile adhesive according to instructions.

The R-value of 10.5 outperforms fiberglass insulation with R-15 on the label. A thicker, stronger insulation panel, the 2.5 Flat Panel is 20% stronger than the 2.0 Flat Panel and 1/2” thicker. This system can fit even tighter on concrete walls and floors because the studs are more deeply recessed and the interlocking edges hold even tighter.

The InSoFast PLUS system allows you to step up the insulation even further. Layer the rigid foam board of your choice on top of either InSoFast interior insulation panels for a cumulative R-value system.
