• IMSl,S) blacks are dry -stacked without mortar and each
side of the wall is finished with a fiber reinforced
concrete coating known as JMSj� Structure/Coal. This
finish makes the wall waterproof and can be textured
as would any ordinary stucco.
The I ISS I system 'has an assymetrical cell
configuration. Reinforcement Is placed closer to the
inside face of the wall, ifi.11:
. from the outside face, d = 5.5 laches
from the inside face, d -. 'Inches
Insulation i placed in all ungrouted cells as the al
being constructed. The insulation is node of non-toxic
expanded o I t r FPS and specially molded t
fit within the block cores.
Vertical raceways are provided every 811 within the
interior
face of the wall to allow for electrical, telephone
r television wiring.
Engineering Design Recommendations
III I(6) Structures are designed a
reinforced mason r in accordance with
Chapter 1 of the Uniform Building Code
or ACI 530-92 "Building Cod
Requirements forMasonry Structures
".
When designing with insulated masonry,
it is important to remember the two
basic principles of maximizing thermal
efficiency, vain/.
1. Space reintorcement as far apart as
possible to maximize the amount ot
insulation. Thee maximurn spavin t
be used with the IMSI-®R System is 48
inGhes on center both horizontally
and vertically.
2. Avoid creating thermal bridges or
areas in the wall where heat flaw is
essentially uninhibited.
See 1.C. . . Evaluation Service, Inc.
Evaluation Report No. 4997 for the
allowable values and/or conditions of
use concerning the IMSI° System. The
design recommendations given in this
report are shown in the figure to the
right.

Thermal Performance
The I 1) System i . "mass" system and such,
thermal mass is considered as part of overall thermal
performance. Thermal mass is the ability of a wall system t
store heat higher -thermal mass means a greater ability
store heat. Wood frame is a low mass system, or a system
which stores little heat (about % that of concrete masonry)
.
Heat is stored during the day and released t night.
Because of this storage capac ity. the overa II ti me f - r the heat
to pass through a mass. wall is much greater than for a low
ass wall.
Thermal performance is the measure of a systems energy
efficiency. It has long been recognised that masonry
buildi n use heating and coaling differently than
lightweight (wood frame) buildings. For example, becausle of
masonry's thermal ma , surnmer cooling needs are shifted

to the evening when utility rates are lower. Also, peak
heating and cooling requirements are lower, rencanin that
smaller, less expens ive furnaces and air conditioners may be
used.
The following thermal performance values ars for a
prototypical residential building (1,8(]0 square foot ranch with
windows and doors comprising 20°'Q of,the total wall area) in
selected climates, The ENVSTD compliance program for
ASHRAEIiES Standard 90.1 was used to determine the R-
vafue of a woad frame wall that would have the same heating
and coaling loads as an Identical IMSI� wail. The values
should not be construed to mean that the IMSIcE) System has
an R -value greater than its tested steady state value (R =
13.6), but rather the IMSf@) System has performance
equivalent to that of a low mass wall with a higher R -value.
