A superior solution for sealing and insulating your home's crawl space walls
what Is Crawl Space Wall Insulation?
Crawl space wall insulation is a system that seals and insulates the foundation walls to control moisture and improve energy efficiency. SilverGlo™ uses graphite-infused polystyrene with a built-in radiant heat barrier to create a continuous layer of R-11 insulation along the crawl space walls. The closed-cell material resists moisture, helps block humidity from entering the space, and directs any wall seepage down to the drainage system. This approach supports a drier crawl space while helping reduce strain on your heating and cooling system.
When to Use Crawl Space Wall Insulation
Cold Floors in Winter
Cold Floors in Winter
If your floors feel cold during the winter, your crawl space may be letting outside air affect your home. When foundation walls are not insulated, cold air moves freely through the space below. That temperature loss rises into the living area above. Insulating the crawl space walls helps reduce heat loss and keeps indoor temperatures more consistent.
High Energy Bills
High Energy Bills
Rising heating and cooling costs can point to poor insulation in the crawl space. When outside air and humidity enter unchecked, your HVAC system has to work harder to maintain comfort. Over time, this increases wear on your equipment and drives up monthly bills. Proper wall insulation helps create a more controlled environment below your home.
Damp or Humid Crawl Space
Damp or Humid Crawl Space
If you notice damp walls or a humid crawl space, moisture is likely entering through the foundation. That moisture can raise humidity levels throughout the space. Over time, this creates conditions that support mold growth and wood rot. Installing moisture-resistant wall insulation helps block humidity and support a drier crawl space.
Sagging or Fallen Fiberglass Insulation
Sagging or Fallen Fiberglass Insulation
Fiberglass insulation often absorbs moisture and begins to sag or fall from the ceiling. Once wet, it loses much of its insulating value and can become a breeding ground for mold. Piles of damp insulation on the crawl space floor are a clear sign the current system is failing. Replacing it with closed-cell wall insulation provides a more durable and effective solution.
Visible Condensation on Crawl Space Walls
Visible Condensation on Crawl Space Walls
Moisture forming on foundation walls is a sign that warm, humid air is meeting cooler surfaces. This repeated dampness can affect framing and insulation performance. Over time, it contributes to mold and wood rot. Wall insulation with a built-in vapor barrier helps control this moisture at the surface.

OUR Crawl Space Wall Insulation PROCESS
Inspect the Crawl Space Walls
We begin with a detailed inspection of the crawl space walls and overall conditions. This includes checking for moisture intrusion, air leaks, and existing insulation. We also review how the crawl space connects to the rest of the home. This allows us to recommend the right wall insulation approach.
Address Moisture and Air Gaps
Before insulation is installed, visible gaps, seams, and problem areas are identified. Controlling moisture and limiting outside air movement is critical to long term performance. If needed, drainage or vapor control components are coordinated as part of the plan. Proper preparation helps the insulation perform as intended.
Install Wall Insulation Panels
Insulation panels are securely attached to the crawl space walls. Each section is fitted tightly to reduce heat transfer and limit air movement. The goal is to create a continuous insulated surface along the perimeter. This helps stabilize temperatures inside the crawl space.
Seal Seams and Transitions
Seams, joints, and transitions around piers or penetrations are carefully sealed. This step helps maintain consistent thermal protection and reduces gaps where outside air could enter. Attention to these details improves overall system effectiveness. It also supports better energy performance.
Final Review and System Check
After installation, the crawl space is reviewed to confirm full wall coverage and secure attachment. We verify that insulation is properly integrated with any existing vapor barrier or waterproofing components. The result is a sealed, insulated perimeter designed to improve comfort and efficiency throughout the home.

What is SilverGlo™ Crawl Space Wall Insulation?
SilverGlo™ is a graphite-infused expanded polystyrene insulation designed specifically for crawl space walls. It provides R-11 insulation and includes a radiant heat barrier on the visible surface. The closed-cell material resists moisture and helps create a continuous layer of insulation along the foundation walls. It is installed as part of a complete crawl space repair and encapsulation system.
How is SilverGlo™ different from fiberglass insulation?
Fiberglass insulation in crawl spaces often absorbs moisture, which reduces its effectiveness and can cause it to sag or fall. Once wet, it can support mold growth and lose insulating value. SilverGlo™ uses closed-cell insulation that does not soak up moisture. It maintains its performance even in damp crawl space conditions.
Will crawl space wall insulation help lower energy bills?
Yes. Insulating the crawl space walls helps reduce heat loss and limits the impact of outside air on your home. With R-11 insulation and a radiant heat barrier, SilverGlo™ improves thermal performance below the home. This can reduce strain on your heating and cooling system and improve overall energy efficiency.
Does SilverGlo™ help control moisture in the crawl space?
SilverGlo™ helps block moisture from entering through foundation walls. The waterproof polystyrene panels resist dampness and help direct any wall seepage down to your drainage system. By limiting humidity and surface moisture, it supports a drier crawl space environment. This helps reduce the risk of mold, rot, and musty odors.
Can SilverGlo™ be combined with other crawl space solutions?
Yes. SilverGlo™ is designed to work with floor insulation, vapor barriers, and crawl space drainage systems. It is often installed alongside TerraBlock™ Floor Insulation, CleanSpace® Vapor Barrier, and drainage or sump pump systems. Together, these components create a sealed and insulated crawl space. This integrated approach improves moisture control and energy performance.
