From: Jenny Readwin, Plans Exarnin
Subject: Use of Corbond Spray on Insulation.at 21402 80"' Ave W. in unvented attic and
wall cavities for garage ADU.
The applicant of the subject permit application is requesting approval of Corbond spray -on
rafters or
insulation, a closed cell polyurethane product. This product will be sprayed between
roof trusses on the roof sheathing. The manufacture requires.no venting in order to create an
isolated warm air space. The applicant is requesting use of R806.4, a code section that will be in z
tion detail
the future 2006 IRC for unvented attics. Per our request the applicant subrilitted.a. sec
(see attached) to Corbond Corporation and we recieved a letter from the manfucaturer (see 0
attached) stating that this product meets all the requirements of R806.4 in this specific
application.

that they have approved this product on a case by case basis in their jurisdictions. M

Lastly, I contacted Chuck Murry. who is an Energy Specialist from the Washignton State
University Energy Program to see if there were any State Energy. Code issues with using this M
z
product. He confirmed that there would not be any code issues with using this product but that it

Based on all information submitted and people I spoke to, I recommend approval of Corbond
insulation for the applicant to use in the unvented attic and wall cavities of their Accessory
M m

Dear Plans Examiner: X
am
C
This letter is to describe some revisions to our original interior remodel permit and also M
0
to request an alternative design approval for insulating the structure.
C:
ceived approval of an Accessory Dwelling Unit permit from the
As you are aware, we re M
z
Planning Department, ADU-2005-91, subsequent to our initial approval of the remodel
JO
permit for the interior of the garage.- The proposed revision adds a kitchen to the Z
habitable space on the second floor and submits the required recording documents for.
the ADU.. This change will result in 2 additional domestic water plumbing fixtures, a
CO)
-n
sink and dishwasher, and an additional gas piping fixture, the stove. However the gas 0
fireplace is being removed so stove fixture is really just a replacement.
M m
Iso, we have changed our heating arrangement. We are replacing the cadet wall
A
0.
heaters with 4 hydronic wall radiators, 2 in the main kitchen and living area and one.
0 m
each in the bathroom and bedroom. I'm not. sure.if these should be added to the C 0)
(A
plumbing fixture count or not. M 0
Z
Regarding insulating the building. We would like to use a rigid closed cell urethane
foam. It will meet or exceed the required R-21 for the Walls and R-38 for the ceilings. X
However, because it is sprayed onto the inside of the wall sheathing between stud and
rafter bays no roof ventilation is provided. I have included some testing documentation Z
that confirms that the closed cell design of the. insulation 'Completely isolates the interior
CD
and exterior climates, meaning that no moisture can migrate from one side of the
insulation to the other. This eliminates any condensation on the sheathing which could
0
lead to rot. Since roof ventilation is required to provide for the venting of warm moist air
M
Which might condense on the sheathing causing roof, rot and failure, no ventilation is
needed when the interior and exterior climates are effectively isolated;
Thank you for your consideration.

Corbond Corporation - Assessing Equivalency
Position Statement #9
September 1, 1997
When assessing a spray foam product's equivalency to CORBOND@, it is important to pay
attention to the following:
Fire rating. - CORBONDO is, *Class I at 4". Our philosophy has always been to make a
product with as low flame spread as the chemistry will allow. We feel this is only right in
Z
peoples houses and other occupied buildings. (*ASTM E-84 tes t)
0.
Labeling - CORBOND@ satisfies the labeling requirements of UBC Section 2602.3, BOCA
0
2603.2 and SBCCI 2603.1.2
CD
Density - CORBOND@ is 1.8 lb/cu ft. density min imum at 5,000 ft elevation. At sea level add

strength, permeability and R -value retention. A product manufactured to 1.8 lb density below,
0 0
C
1000' elevation will loose .2 lb at 5000' and thus be approximately 1.6 lb density. This can
substantially affect the finished product which then falls short in all respects.
M
Mz
Application Temperatures - CORBOND@ may be.applied down to 20IF or colder in the right
c onditions and still maintain its dimensional stability and adhesive quality without losing its
M
specified characteristics.
0
Pass Thickness - CORBONDO may be applied to 4"-5" in a single pass and not lose its

CORBOND@ to allow an impressive pass thickness and still maintain the product core.
characteristics.
Aged K factor - CORBOND@ report s its K & R factor results from aged test samples (ASTM C-
ZI
518, C-177).
Catalyst - Changes from CFC to HCFC required a substantial increase in catalysts to kick the
0
..systems over. Some of these catalysts have an odor resembling un -washed socks. Corbond
Corporation found these to be very offensive for use in a house. They were also -difficult for
0
M
applicator tolerances. Again we chose a safer catalyst group that we felt was worthy of our
brand name.
Resin - When U.S. treaty obligations required the switch to HCFC blowing agents, Corbond
Corporation engineered around the more expensive traditional resins. At the same time ester
resins became popular based solely on price. We believed that the polymer characteristics and
the more caustic catalysts required for these less expensive resins were unacceptable for
housing and for handling.
Color - Corbond's trademarked light lavender color provides owners, architects builders and
code officials a clear way of recognizing the distinctive CORBOND@ product..
Our R&D has generated a product of a quality unsurpassed in medium'density spray
polyurethane HCFC technology today. We have found that a compromise in any of the above
key areas produces a product that is unable to measure up to the CORBOND@ standard of a
quality engineered system. Unless that standard is met across the board - product equivalency
has not been satisfied.

What you should know about R-Vallues
The chart shows the R-values of CORBOND@ insulation. "11" means resistance to heat flow.
The higher the R-value, the greater the insulating power. Compare insulation R -values before

you buy.
There are other factors to consider. The amount of insulation you need depends mainly on the
