Crawl Space Foam Insulation

Crawl Space Spray Foam Insulation Near Portland, Salem, Eugene, and Roseburg

In a crawl space, there is very little room to move around. But the area must be insulated to keep it airtight as well as watertight. If not, standing water and stale air from your crawl space can enter your home and create problems.

Closed-cell spray foam insulation applied in the crawl space is a game-changer for individuals in the insulation industry. It is easy to apply for the experts from Josh Lowe’s Dr. Energy Saver and the state-of-the-art product provides versatility and maximum R-value for your crawl space that other materials cannot touch. The water resistant polyurethane spray foam provides a long-lasting and thorough solution to your insulation issues.

That is why it is such a favorite for homeowners in the Western Oregon and Southwest Washington areas.

Advantages of Spray Foam Insulation

For customers in our area, spray foam insulation proves a great solution for crawl space insulation. Some of its advantages include:

R-value: Closed-cell spray foam has a higher R-value per inch than any other commonly used insulation material. It checks in at R-6.2 or higher, depending on the formulation.

Air barrier: Spray foam air-seals and insulates in one step, making it quick and easy to apply. Its ability to expand and fill gaps and cracks make it an ideal air-sealing material that stays in place in tight quarters because of its super-adhesive qualities.

Water resistant: The closed-cell structure of polyurethane spray foam stops moisture in its tracks, a valuable asset in the dark, moist environment of a crawl space as it will help prevent mold growth. The closed-cell structure means water can’t migrate from one cell to a neighboring one.

Foolproof: A gap of 5% in your insulation coverage area can diminish your overall protection by as much as 50%. With spray foam insulation, it is much easier to achieve optimal coverage in a tight space.

Secrets of Success to Applying Spray Foam

To maximize the impact of spray foam insulation in your crawl space, there are key secrets to success. First and foremost, you need to know which type of foam is best for your crawl space. The choices include: 1-part foam: Single-component foam is super-sticky and comes in pressurized cans. Immediately after application, it expands at different rates. Because it seals gaps as well as insulates, this product is often referred to as an “insulating foam sealant” and is used in smaller areas. 2-part foam: To insulate an entire crawl space with spray foam, contractors use a 2-part polyurethane foam that comes in a pair of pressurized metal containers. When both the resin and a catalyst are mixed together at the nozzle, a foaming chemical reaction takes place that causes the material to expand. Adding spray foam also includes two important conditions that you must consider during the application process: 1. It is a tricky application: An experienced hand is required when applying spray foam, especially two-part foams. With varying expansion rates and other qualities, the spray foams make it difficult for someone other than a professional to get the most of this material. 2. It is temperature sensitive: Cold temperatures affect the chemistry that creates the foaming action. It is critical to keep spray foam cans or two-part foam canisters within a specific temperature range for a successful application.

Frequently Asked Crawl Space Insulation Questions

What kind of insulation should I use in my crawl space?
Most people see fiberglass batting under their homes, yet for a more effective and long-lasting solution, closed-cell spray foam is your better choice. Critters cannot rip it down to use for nesting material (they love to use fiberglass to build nests under your house!). Spray foam is applied to the underfloor; it does not sag and become useless like fiberglass batts do. The floors in your house will be warmer to walk on because of the closed-cell spray foam underneath.
How do you insulate a crawl space ceiling?
Each home is unique and should be evaluated for the best solution. Options include closed-cell spray foam and fiberglass batts. If your crawl space is not tall (most people’s are not), it’s worth it to pay someone else to crawl in there and attach the material to the ceiling.
Should I put a vapor barrier in my crawl space?
Yes, for a few reasons. It helps keep moisture from seeping up from the ground (and then in to your house). If you or a service person needs to access under your home, it makes it a bit easier to move around. There is also a better solution with a much thicker three-layer liner when you encapsulate your crawl space. It has a drainage matt, a foam insulation layer, and then a 20-mil thick liner on top.
Is spray foam good for crawl space?
Closed-cell spray foam is an optimal solution for insulating your home’s crawl space. Critters cannot rip it down to use for nesting material (they use fiberglass to build nests under your house!). Because spray foam is applied to the underfloor, it does not sag and become useless like fiberglass batts do. It also seals nooks and crannies so there is less air from the crawl space entering your living space. Closed-cell spray foam is the better, longer-term solution.
Should a crawl space be insulated?
A resounding yes! If you want to be more comfortable in your home, save on energy costs, and breathe in less air from the crawl space, and help control humidity in your home, a well-insulated crawl space (encapsulation or spray foam) are the best solutions.
