Crawl Spaces
Crawl Space Insulation
Insulating your crawl space keeps conditioned air where you want it and adds a layer of defense against the temperature swings and moisture that damage floors and framing above.
Batt insulation — sold in rolls or batts — is the most common and widely available type of insulation for crawl spaces, wall cavities, and attics alike. It's made of mineral fiber, typically processed fiberglass, and fiberglass batts themselves are made from molten glass spun or blown into fibers using a mix of recycled and virgin glass.
Batt Insulation
Batt and blanket insulation is used to insulate below floors, above ceilings, and within walls. It's generally the least expensive insulation option, though it requires careful, consistent installation to perform the way it's rated to — gaps and compression both reduce its effectiveness significantly. It's a tried-and-true product that's been field tested for generations.
Why Crawl Space Insulation Matters
Uninsulated or poorly insulated crawl spaces let outside temperatures transfer directly into your floor system, making rooms above harder and more expensive to heat and cool. Insulation installed as part of a sealed, encapsulated crawl space also helps guard against condensation forming on cold surfaces, which is one of the ways moisture problems get started in the first place.
Frequently Asked Questions
It depends on your home's construction and the crawl space's exposure — an inspection is the best way to determine the right R-value and whether your existing insulation, if any, meets current recommendations for our region.

“Rob and his crew are super. I had a very big project to renovate a 130-year old farmhouse. They worked diligently to put in new piers, new girders, and new joists. Then they also help to fix some frames and add subfloor. This allowed me to move on. Really enjoyed working with Rob.”

“Very professional! They carried out their task while going the extra mile. It was obvious to me that quality is of great importance. They left it better than they found it. I would recommend them to my greatest of friends and family.”

“After having some minor flooding issues, we contacted Triangle Reconstruction and they were amazing in their ability to identify the issues and the best way to address it. What was most impressive was the team that came out and did the work. They were probably the most professional and organized crew we've ever seen work on our house. Brian, our rep, and Rob, the owner, regularly checked in on their work and kept us updated on the progress. I hope I never have to deal with flooding issues again, but if I do, I'll call Triangle Reconstruction again.”
