Vented Vs. Unvented Crawlspaces for Homes in Manchester, TN: What You Should Know

Your crawlspace might not be the first thing you think of when considering your home’s energy efficiency, but its structure can significantly impact comfort and durability. For homeowners in Manchester, Tennessee, understanding vented and unvented crawlspaces is essential for making an informed choice that best suits local conditions.

Vented Crawlspaces

Vented crawlspaces are designed to allow outside air to circulate, which can help manage moisture levels in certain climates. However, in the humid environment of Tennessee, vented crawlspaces can actually increase moisture exposure, leading to issues like:

  • Mold and mildew growth
  • Wood rot in structural beams
  • Pest infestations, as moisture attracts termites and other insects
  • Increased allergens and musty odors inside the home

These conditions can not only affect your crawlspace but can also impact the air quality throughout your home, making proper ventilation a crucial consideration.

Unvented Crawlspaces

Unvented, or conditioned, crawlspaces are sealed to keep moisture out and maintain controlled humidity levels. Complete Insulation’s TRU-Encap system is designed to encapsulate vented crawlspaces with closed-cell polyurethane spray foam, effectively creating an unvented space. This process provides a moisture barrier, insulation, and increased protection for your home’s structure.

Benefits of unvented crawlspaces include:

  • Improved air quality and reduced allergens
  • Better energy efficiency and lower utility bills
  • Long-term protection against mold and rot
  • Enhanced structural integrity

“I had a fire in my attic and needed all of the contaminated insulation removed. I am *AMAZED* at how thorough the hard working folks at Complete were. You could almost eat off the floor of the attic. The entire crew was courteous, quick and more than fair with the price. Highly recommend.”

“The team who came from Murfreesboro, TN to our house in Chattanooga were amazing. We have a very large home. They removed all the old insulation from our three attics, sprayed with a decontaminate and then sprayed all the new insulation. All in one very long day. They were great to work with, came went they said they would, answered all our questions. Had to put the tubes all the way from the attic down to the first floor and out to the truck. They covered all the floors, stairs etc and left the place spotless. We are very pleased and would highly recommend this company.”

“I was building my own custom home and "interviewed" several spray foam insulators. It was clear Moody Ozier had a deeper knowledge of air sealing, R-value, and building codes than anyone else, so I went with Complete Insulation. He really took an interest in my hyper efficient build and came up with additional engineering ideas to further improve the efficiency of my home. I cannot say enough good things about Moody and Id tell anyone he's trustworthy, efficient, and knows the insulation and air sealing business to great depth. Jose, Fredy, and their crews showed up on time, in uniforms, with clean trucks and did a wonderful job on instal AND cleanup. They were incredibly professional at every step and it was clear they had years of experience. I recommend Complete Insulation to anyone with encapsulation and/or insulation needs whether you are new construction, retro fit, investor, or otherwise.”
