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.

"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 Comments un r info red wall bearing 5,000 lb/ft classified as Imp rmeablefl sound transmission loss at 500 MHz concrete dry i f 1 Pf 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.
