You might not know much about vapor barriers, or even have heard of them before, but Allied 24/7 Property Restoration is here to let you know that they are extremely important for your home! Here are a few things you should know about why vapor barriers matter. When you’re ready to learn more, or need professional water damage restoration in Montana, just give us a call!

Vapor Barriers Protect Your Crawl Space

Your building is susceptible to moisture damage, and vapor barriers are a critical component of protection against this situation. Here’s something to think about: A typical home can produce about 1 gallon of water vapor per every 100 square feet. That means your home could accumulate 12 to 14 gallons of water vapor in a single day. That’s a lot of moisture! Even worse, water vapor rises, which means it will inevitably reach your crawl spaces and attic in as little as two hours. When it gets there, it will slowly eat at the plywood on the underside of your roof. You can see now why a good vapor barrier comes in handy!

Vapor Barriers Come in Several Helpful Varieties

If you’re concerned that a vapor barrier might not be right for your particular type of home, don’t worry—there’s a variety of vapor barrier options out there to meet your needs:

  • Loose lay vapor barrier: This barrier is a step up from no protection at all, and can prevent about 20 percent of moisture from reaching your plywood.
  • Bonded vapor barrier: This type of vapor barrier is applied by glue to the footer and seams of your attic system, and the seams are then taped for optimal protection. You’ll see up to twice as high of a percentage of protection compared to a loose lay barrier—about 30 to 40 percent.
  • Depressurized vapor barrier: In most cases, this type of barrier is the top option for protecting your home. It is mechanically fastened by using a radon pressure pump, and is then vacuumed to the structure for an extra tight, impenetrable seal. It is a permanent structure that is capable of stopping up to 90 percent of potential water vapor from getting into your roofing system. As an added bonus, this system also prevents mold growth in your attic and crawl spaces.

Remember to have a professional take a look at your attic to make sure you don’t need water damage restoration in Montana first. It’s important to have your home in good condition before you add a vapor barrier in order to get good results.

Moisture protection is not something to be taken lightly. Some home repairs can be completed in a do-it-yourself fashion, but water damage restoration and vapor barrier installation are work best left to professionals who have the knowledge and experience to ensure a job well done. If you’re ready to start protecting your home, give the experts at Allied 24/7 Property Restoration a call. We look forward to assisting you!
