closed cell SPF have permeability ratings that are far lower than traditional insulation materials, making either SPF type an ideal air barrier material. The number of inches of foam necessary to create and air barrier is dependent on the foam type. Closed cell SPF is typically an air barrier at 1 inch. Open cell SPF is typically an air barrier at 5.5 inches or more. MOISTURE MANAGEMENT When considering moisture management strategies, air movement is the most important variable to be concerned with. Controlling how water enters and leaves the building envelope is a necessary step in order to maintain a healthy, energy-efficient and durable building, as 80 to 90 percent of a building’s issues are moisture related. Water can enter the building in two ways: • As a liquid • As a vapor In liquid form, water often enters the building envelope through rain, snow or the ground. Although older buildings have some sort of water management strategy in place, poorly designed or aging water management systems can IRAQ – BETWEEN MARCH 2008 AND DECEMBER 2009, THE U.S. MILITARY IN IRAQ BENEFITED FROM THE PERFORMANCE OF SPF Tom Harris, project leader with Honeywell, was onsite in the warzone with 26 other Americans for five months spraying various structures – from 6 a.m. to sundown, every day. The teams methodically covered 17 Forward Operating Bases (FOBs) from North, to Western and Southern Iraq. “This is what we did,” said Harris. Brigadier General Anderson, the military’s senior logistician in Iraq, was responsible for the tremendous amounts of fuel needed to power the bases. According to the General’s NYT Op-Ed piece (Jan 2011) tanker convoys were costing the Pentagon $24B USD per year, $66M per day in A/C costs, and realizing casualties in 1 out of every 24 convoys. But that all soon changed. A comparatively small $95M for 2” of closed cell SPF with acrylic coatings installed in dangerous, rugged conditions on tents, hangars and hospitals led to reduced noise, increased comfort and better indoor air quality. Harris noted in one case a hospital that typically had ¼” of dust on the floor. “It was everywhere – you’re in a desert,” he said. But after the SPF, the hospital almost never had to wet and sweep the dust to clean the facility. Additionally, ambient air temperature in Iraq was 137 degrees in the summer. Operating six 15-ton A/C units on a large General Purpose tent running 24/7 brought the temperature inside to 97 degrees. After sprayfoaming the tent, and shutting down three of the units, indoor air temperatures were reduced to 67 degrees. SPF as a force multiplier cut about 15 truckloads per day of base fuel from convoys, and according to the General reduced the energy requirements of the foamed structures by 80%, saving $1B USD per year. “This was an absolute life changing event,” Harris said. “These were extremely busy bases, especially at night. The professionalism and discipline of these troops are indescribable and it was my greatest honor to be part of the project.” www.sprayfoam.org | SPRAYFOAM PROFESSIONAL 31 http://www.sprayfoam.org
