You may or may not have noticed a few new construction homes in your city that get this black coating instead of any house wrap paper products. The black coating is an exciting, newer product called EnviroDri; we believe EnviroDri is more efficient in function and cost savings than any other type of house wrap. This product streamlines the construction process and eliminates any worry a potential homeowner might have about any leaks or energy efficiency.

Homes need to have some sort of water resistive barrier over the sheeting to prevent water from entering the house from the outside but breathable for moisture to escape from the inside of the home. Typically, house wrap was been used as this water-resistive barrier; it is taped onto the home in large paper sheets. Any place the house sheeting meets another piece of sheeting the seam should be taped then the wrapping should be layered to provide protection as the house settles with age. Since the wrapping is put up in large sections, it’s common practice to add staples through each section to prevent the wind catching the paper and ripping it before the siding can be installed over it. As you can imagine already there are a few possibilities where this form of house wrap can fail. Any place the paper has been mechanically fastened (stapled) on to the home is at risk for a leak since the barrier has been penetrated. This is a very low risk, but, still a possibility. Depending on how fast your home is built, there could be a good span of time where your house sits with only house wrap on it while it waits for the siding or brick install; strong winds or storms can pull this house wrapping off or tamper the seals if not installed properly. While it is in the manufacturer’s installation instructions to overlap over sheeting seams, the installer might not follow this in efforts to cut their own material costs. Let’s say everything was installed properly and you been living in your home for a few years without any leaks or problems but a storm comes and blows off some siding. Your house wrap in that section is now exposed and if the storms or strong winds continue, the house wrap could become shredded in the exposure.

EnviroDri is a water resistant membrane that is sprayed onto your home after it’s been sheeted. The membrane and the wooden underlayment function as one unit once the membrane is cured. All seams have a water resistive “mesh” applied over and then sprayed again by the EnviroDri membrane. The mesh flexes with the seams the house settles, effectively protecting it throughout the shifting. Since EnviroDri is sprayed on there won’t be any mechanical fasteners piercing the barrier, so absolutely no risk of leaks due to that. Since the membrane is adhered to the sheeting, if your siding blows off your house is still protected from any storms or high winds.

EnviroDri is more energy efficient than any other form of house wrap. It’s more efficient because it’s a tighter protection than any form of house wrap because there is no space between the sheeting and the barrier. This allows you to go from a a 2×6 wall with R-19 insulation to a 2×4 wall with a R-13 insulation and still see energy improvements. The attic insulation can also go from a R-50 to an R-30. All of this saves money on materials and energy in the long run.
