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.

EnviroDri on Apartments in Bloomington Il

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).

 

The Importance of Kick-out Flashing

Spring showers bring leaky gutters- Wait no, that’s not right! We’ve recently had a fair amount of homeowners call because they are tired of leaking gutters. It’s usually the lack of kick out flashing which gives the appearance of a leaky gutter but often has hidden disasters associated with it.

 

What is a kickout flashing?

A Kick out flashing is a tiny but valuable piece of metal that diverts water into the gutter. It’s installed along the wall that the gutter end terminates into. The image below shows a correct kickoff flashing. It’s important to make sure the kickout overhangs a decent amount into the gutter to ensure no water runs along the side wall behind the gutter endcap.

Proper Kickout Flashing

Why is a kickout flashing necessary?

Kick out flashings are needed to direct water into the gutter- in these specific areas, siding is often times notched to fit around the roof section and has the possibility of letting water slip behind the siding and run down the interior wall. Beyond the obvious trouble of improper water control, if your house doesn’t have any housewrap or housewrap failure, the sheeting underneath will often be moldy or rotting without a proper kickout flashing.

Bad Kickout Flashing
Kickout flashing is too short- Water is still likely to run against wall

The images below are of a home in Bloomington, IL that had a powerful combo of the housewrap installed incorrectly and no kickout flashing. Every place the gutter butted up against a side wall, the OSB underneath was completely rotted- our Carlson Exteriors guy was able to push his hand through the OSB easily.
