"Rainscreening for siding has been around a long time. Unfortunately, it was
always wood and we all know that wood does not hold up in that environment, a
drainage plain for water. A lot of products are streaming onto the market

claiming to be the latest in rainscreen technology, even built right into house

wraps. I have to say without a proper drainage plain of at least 1/4 - 1/2 inch

they just don't allow enough room for true drainage. The moisture just stays

inside the drainage plain if enough air isn't allowed inside. Now with Roll-On,

they allow at least 3/8'' and this creates the perfect balance between
allowing draining and giving enough room for natural air movement within the
plain. Now remember, water will move in very tight spaces; it won't just dry
out without air movement. I live in North Carolina, and moisture can stay
inside a wall for more than half the year, sometimes longer if the winter
doesn't come in dry. We have to have air movement inside the drainage plain
to have this occur. I have used Roll-On with just a few simple instructions
and pictures on a large siding project including a detached garage, over 70
squares of composite siding. One of the complications with composite siding,
is that water cannot travel through the siding if it stays in the drainage
plain, it gets forced into the house. We installed the rain screen through a
winter and many storms, the walls always were bone dry quickly after the
storm passed. That only occurs because of the rapid air movement that
happens with a larger drainage plain, like Roll-On provides. Roll-On allows
for quite a bit of installation forgiveness, because of its independence
from the house wrap. Tear your house wrap with the built in rain screen,
destroying your drainage plain - think your contractor is going to fix a tear!?
Roll-On is designed with the rough handling that occurs on a jobsite. I
wouldn't say it is indestructible, but it is contractor tough. I have seen a
lot of siding failures and in NC they are always about moisture control and
improper installation. I cannot emphasize how important a drainage plain is
in siding of any kind and the importance of the air movement associated with
that. It is for this reason that I highly recommend the use of Roll On rain screen

on any of your siding projects."

"This rainscreen system is the best system on the market

and I can say that because I'm using it on a job here in Indianapolis. If anyone out there has not tried this system

and needs a good recommendation, please give me a call because I can honestly tell you this system is awesome.."
