Carlson Exteriors gets excited about Tremco’s product, Enviro Dri for many reasons. These range from monetary savings all the way to long term homeowner protection. Before we dive into the behind the scenes of Enviro Dri, many of you might be unfamiliar with it. I’d suggest clicking here and reading this page to get a quick understanding.

The first benefit thats always on everyone’s mind is savings. How can something new save you money? While installation costs might be exactly the same as standard house wrap, using Enviro Dri during a new construction build can allow you to save money in other parts of your build. You can have thinner walls but have the same insulation rating because Enviro Dri is more energy efficient. The lumber savings alone is enough for many builders to switch to Enviro Dri from house wrap.

House wrap can tear easily if left exposed to high winds. Enviro Dri is a liquid that applied to your sheathing; no part of Enviro Dri can be ripped or destroyed by high winds or any harsh elements. During the build of your new home, you can rest assured that your home is protected if it takes a little longer than expected to get your siding installed. If you aren’t building your home, knowing that you you have Enviro Dri protecting it gives you a little extra piece of mind if any piece of siding would blow off. If you had a piece blow off or break, any exposed house wrap may also rip leaving the OSB exposed. Enviro Dri eliminates this from ever being a problem.

Enviro Dri is a more hardy of a moisture barrier. It can also be used under all products (brick, stone, stucco, etc). It will stand up to surface active contaminants that are frequently found in wood, stone, fiber cement siding. Over time these contaminants can break down house wrap’s barrier. There are no mechanical fasteners used in Enviro Dri’s application. Since it’s a liquid that’s applied, there are no nails or staples keeping it attached. Normally these areas could leave you exposed to a water infiltration. With house wrap your home will have many seams that could fail. These taped seams could fail from not being taped correctly to not withstanding the settling of your home over time. There are NO seams in Enviro Dri. As an added measure, everywhere the OSB sheets join up, our installers add a mesh strip to flex with the OSB (if needed).

 

Water Management

Uncontrolled water is the biggest threat to homeowners. It’s a slow and silent killer. Here are the most common issues we see on homes.

Lack of Kick-Out Flashings. Even if your gutters are pitched correctly and don’t leak, they may appear to be leaking where the gutter butts up the wall. Or it might look like nothing is wrong at all. Overtime, water constantly slipping between the wall and gutter will find its way behind any house wrap or moisture barrier you have in place. Read more about kick-out flashings

No Downspout Extensions. Often times homeowners remove these extensions out of aggravation. These extensions might seem like a trip hazard, a pain to mow around, or get trampled easily. – but don’t get rid of them! Your home and your foundation need these extensions to route water away from you home. You can add hinges to these extensions to eliminate all the hassle they cause.

Inadequate or No House Wrap. Depending on when your home was built and the history of your city’s building codes, your home might not have any house wrap or moisture barrier. For example, the City of Bloomington, IL did not start requiring any form of house wrap until the late 70’s. Practically all houses built before the early 70’s (in Bloomington, IL) are without house wrap. Siding, bricks, shakes or any other exterior cladding are not intended to protect your home from water intrusion. If your home does have house wrap, it might be done incorrectly: applied in small pieces, too many mechanical fasteners, or taped incorrectly. There are alternative moisture barriers to house wrap at similar expenses- Read about EnviroDri.

Bad Pipe Flashings. Pipe flashing have a shorter lifespan than your roof and will need replaced a few times before you need a new roof. It’s a simple fix but if the flashing is cut too large, water will still get in. Watch Nick Coyle replace a pipe flashing.
