Spray foam insulation, available in closed-cell and open-cell varieties, forms an airtight seal, effectively blocking air leaks and preventing moisture intrusion. This is particularly beneficial in crawl spaces and basements where air infiltration can be a significant problem. For example, a manufactured home located in a humid climate might utilize closed-cell spray foam on the crawl space walls to both insulate and create a vapor barrier. This reduces the risk of mold growth and wood rot. The airtight nature of spray foam also improves the overall energy efficiency of the home by minimizing heat transfer through the foundation.
- Rigid Foam Board Insulation
Rigid foam board, such as extruded polystyrene (XPS) or expanded polystyrene (EPS), provides good thermal resistance and moisture resistance, making it well-suited for a variety of applications. Rigid foam is commonly used to insulate the perimeter of a slab-on-grade foundation. Consider a scenario where a manufactured home rests on a slab; installing rigid foam around the foundation's perimeter reduces heat loss into the ground, resulting in more stable indoor temperatures. XPS boards are often preferred in this scenario due to their higher moisture resistance and compressive strength. The choice of rigid foam board directly influences the thermal performance and longevity of the foundation insulation.
- Fiberglass Batt Insulation
Fiberglass batt insulation, typically made of spun glass fibers, is a cost-effective option that is often used in crawl spaces and basements. The installation process involves fitting the batts between the floor joists of the manufactured home, or, for wall insulation, between wall studs. For example, in regions with milder climates, fiberglass batts can effectively insulate crawl space walls, improving the home's overall energy efficiency. However, it's critical to pair fiberglass batts with a proper vapor barrier to prevent moisture accumulation. The primary consideration when choosing fiberglass batts is ensuring proper installation and adequate protection from moisture to avoid potential issues.
The material selected for insulating the manufactured home foundation dictates the success of the endeavor.

Conversely, when using fiberglass batts, it is imperative to install them snugly between floor joists, ensuring the vapor barrier faces the heated living space. Another consideration involves addressing air leaks around plumbing, wiring, and ductwork by sealing these openings. Inadequate insulation and air sealing in a crawl space can lead to energy loss, mold growth, and pest infestations.
- Slab-on-Grade Insulation
Insulating a slab-on-grade foundation generally involves installing rigid foam insulation around the perimeter of the slab. The foam boards should be installed vertically, extending from the footing down into the ground and up above the finished grade. Proper installation requires careful cutting and fitting of the boards, sealing any gaps to prevent air infiltration. For instance, if the manufacturer home is located in a region with cold winters, this perimeter insulation will help to prevent heat loss from the interior. Installing insulation incorrectly can result in uneven temperature distribution and higher energy bills.
- Basement Insulation
Insulating a basement foundation requires a similar level of attention. Insulation can be installed on the interior walls or the exterior of the foundation walls. If insulating interior walls, materials can include rigid foam boards or spray foam. Regardless of the chosen method, proper sealing and the correct vapor barrier placement are crucial to prevent moisture problems. For example, in colder climates, continuous insulation is often required to prevent condensation on the interior surface of basement walls. For exterior insulation, the process typically involves excavating around the foundation, applying insulation boards, and protecting them with a drainage layer. The correct installation ensures the insulation effectively reduces heat transfer and prevents moisture buildup.
In summary, successful application of how to insulate a manufactured home foundation hinges on not only the selection of appropriate materials but also on the meticulous application of correct installation techniques. Each technique is specific to the chosen materials and the type of foundation, so adhering to these guidelines is a must. These factors ensure that the insulation performs as intended, contributing to energy efficiency, comfort, and the long-term durability of the home. This provides a substantial return on investment through lower energy costs and enhanced structural integrity, making well-executed installation crucial.
