Ltd Project: 1225 Judson Installer: Ian Maple and Jose Vera Location: 1225 Judson, Evanston ,IL Type of Job: Total Building Envelope Insulation Project Description: Jim Blake, Homeowner, wanted the best insulation available in today's market. He chose SPF insulation. His home is two blocks off lake Michigan in Evanston, IL, and built in the late 1800. The project was a total gut/rehab of the building. All four floors were being re-built. The third floor was all cathedral ceilings. A mixture of open cell and closed cell SPF was used. Closed Cell (Corbond) was used on all exterior walls (basement, first, second, and third floors), and cathedral ceilings of the third floor (i.e. the entire roof structure). Open Cell (Sealection 500) was used on the basement, first and second floor ceilings and on ALL interior walls. Benefits of using Foam: Jim Blake choose SPF insulation because of its superiority over all other insulation materials.

Contemporary Living Is Noisy TodayÕs homes are filled with decibel-raising high- tech gadgetry including big screen TVs,computer games,CD players and stereo systems. Add to this the changing dimensions of todayÕs homes Ð we now have home offices,media rooms,spacious kitchens with Ôgreat roomsÕattached Ð and the net result is a noise-laden environment that can adversely affect your familyÕs sleep,stress levels,and quality of life. Consequently, more and more homeownersSources of Noise in a Typical Home are looking for ways toDishwashers, washers, dryers, garbage disposals, blenders, ÒsoundproofÓtheirvacuum cleaners, radios, computers, CD players, stere- homes to diminishos, TVs, lawnmowers and leaf unwanted noises fromblowers. both inside and out- side the home. One of the most economical ways to make a home quieter is to install fiber glass insulation. A good sound insulation package not only increases the comfort of your home but also adds to its value. 1

STCs, IICs and Sound Transmission In the 1970Õs,HUD/FHA set minimum requirements for Sound Transmission Class (STC) ratings for air- borne noise reduction through walls and partitions. An STC value is a single number rating used to charac- terize the sound insulating value of a partition (wall, floor,or ceiling). A partition prevents sound from being transmitted from one area to another. The high- er the STC rating,the less sound will be transmitted through the wall,floor, What Do STCs or ceiling. DifferentMeasure? STC ratings are recom-STC ratings measure trans- mission of speech and other mended for differentsounds in a way that agrees rooms within the homewith how the human ear perceives it. (see below). HUD/FHA also set mini- mum requirements for Impact Insulation Classes (IICs) for impact noise levels through floors. As with STCs, the higher the IIC value of a floor/ceiling,the better its ability to control impact sound transmission. An IIC rating of 50 or higher is considered acceptable.

Noise Control Strategies Most conventionally built partition walls made of lumber and drywall have poor STC ratings ranging from a bare minimum of about 15 to 35. There are a number of measures that can be taken to raise the STC number, including: Acoustic Insulation Fiber glass Insulation Fiber glass acoustic batt By far the easiest and insulation is economical, most economicallightweight and easy to install.

Resilient Channels Plus Acoustic Insulation An even more effective way to increase the STC rat- ing is to use resilient channels between drywall and studs or joists. Properly installed resilient channels will break the vibration path which will help reduce sound transmission. Typically, the drywall is screwed to a flange on these channels, not to the studs.

--------------------------------------- 7
Other Sound Control Strategies Other sound control strategies include using heavier building materials (like adding one or two layers of gypsum to a wall construction) to block the path of the noise through walls, floors, or ceilings. While this creates thicker walls, they may not be struc- turally practical or cost effective. t Guidelines For Installing Insulation in Exterior Walls Exterior walls should be constructed with resilient chan- nels and fiber glass insulation in the stud cavity. If a residence is impacted by overhead aircraft, then resilient channels should be used in roof/ceiling assemblies as well as using at least 9 inches of blown-in fiber glass insulation in the attic. The insulation should overlap the top of the joists by at least 1 inch. Make sure the vapor retarder is toward the heated side of the home. Humid climates may require the vapor retarder to be s Guidelines For Installinginstalled facing the exterior of Insulation in Interior Wallsthe wall. (Check local building requirements for The basic guideline forlocation of vapor retarder.) installing insulation into side- walls is to fit the ends of batts snugly against top and bot- tom framing. (Check local building requirements for location of vapor retarder.) Working from the top down, staple the pre-formed flanges about 8 inches apart until you reach the bottom. Continue this around the perimeter of the room. 5
--------------------------------------- 8
Insulation Choices and STC Ratings Fiber glass and cellulose are the two most common- ly available insulation materials used for sound con- trol. Cellulose manufacturers claim that their insula- tion, when used in a partition, gives higher STC val- ues than fiber glass insulation. This, however, is not accurate. The fact is there is no significant difference in STC ratings between using fiber glass or cellulose insula- tion. This has been scientifically proven by numerous sound transmission loss tests conducted at independ- ent laboratories. Test results have shown STC ratings for walls using either cellulose or fiber glass insula- tion are within 1 or 2 points of each other. Sound Control Practices nInsulate heating and air conditioning ducts by using fiber glass flex ducts, fiber glass duct board or by wrapping or lining the ducts with fiber glass insulation. nInstall thick carpeting and padding throughout your home to help reduce impact sound. nCaulk around windows and use weatherstrip- ping at the bottoms of your exterior doors. nUse solid wood or mineral core doors where privacy is demanded. nInstall acoustic ceiling panels. nDouble or triple pane glass and storm win- dows can all help reduce sound transmis- sion through windows. nSelect quiet, high quality appliances. 6
--------------------------------------- 9
nInstall telephones, doorbells, intercom or audio built-ins on interior walls only, never on com- mon walls or corridor walls. nCaulk holes made by wiring which penetrates connecting structures with elastic non-harden- ing caulk or dry packing. nSeal openings around ceiling fixtures so they are airtight. nMake use of plants,draperies and wall hangings throughout your home. The more ÒsoftÓobjects in a room,the more sound is absorbed. nMinimize window sizes facing noisy areas. nAsk your builder to make sure electrical boxes fit snugly in drywall. Gaps can be caulked to reduce sound leaks. nAsk your builder to develop a well-planned lay- out to minimize the noise of flowing water. Insulate walls containing drain pipes. nAsk your builder to seal under all bottom plates as the walls are being built. nAsk your builder to avoid undercutting doors if possible. Frequently,doors must be undercut to get proper air circulation for the HVAC. A sim- pler solution to ensure proper ventilation is to keep doors open when rooms are not in use. 7

SOUND SCIENCE TM The millions of semi-rigid open cells in Sealection500 insulation work to absorb sound waves at varying frequencies, making it possible to design cost effective walls and ceilings with a Sound Transmission Class (STC rating) of 50 or more. TM Houses, buildings, and rooms insulated with Sealection500 all enjoy the benefits of protection against unwanted noise! KEEPING SOUND IN NOT OUT A fairly quiet room has between 30-50dB of background noise. A home theatre boasts of up to 100 dB, which means your walls need a STC rating of 50 or more to giveSpray Foam the rest of your home a little peace and Insulation Properties quiet. 3 Density:0.47 - 0.5 lbs/ft 2 Tensile Strength:5.6 lbs/in Typical wood stud construction using fiberglass insulation and 5/8” drywall onClosed Cell Content:4% both sides has an STC rating of 27-34.

TMTM Quiet-S-WallsSystems using Sealection500 spray foam will have a better performance at high frequencies than at very low ones.

Innovative Insulation Solutions, Ltd Union Pacific -Oil Recycling Tank Union Pacific Railroad Yard Melrose Park, IL Installer: Martin Gudinoand Oscar Espinoza Type of Job: 19,000 gallon Tank Insulation Square footage of Job: 2000 Square feet: sprayed/coated Equipment Used: Gusmer HF-1600 / Gap Pro Guns Number of people needed for the Job: Two man sp Number of days required by the Job: Three Days Special Requirements: Wind Screen and Fall Protection Foam and coatings used: GacoWestern 273 Roof Foam and GacoFlex A-30 Project Description:Union Pacific RR has a locomotive engine oil recycling initiative. Union Pacific’s Chicago rail yard has hundreds of locomotives, which produce thousands of gallons of used oil annually. Union Pacific collects the used oil, treats the oil to remove water, and then sell the treated used oil to recyclers. The recycling process always came to a stop during the winter. Union Pacific RR decided to insulate the 19,000-gallon oil collection tank with SPF, so the combination of the SPF and the heater they installed will permit the oil recycling to continue year around. Benefits of using Foam:SPF insulation was chosen to insulate the tank, since it was the only way to insulate the tank in an effective manner. No other method would achieve their goal of allowing the oil recycling process to continue through the winter. The SPF was able to conform to all the unusual and irregular surfaces of the tank. We were also able to insulate the tank in a very short period of time -sprayed and based coated in one day -two more days for the topcoats.
