The kind of use and abuse schools endure calls for solid construction. Due to masonry's ability to withstand such treatment and the fact that a brick school building presents a traditional school image for many people, masonry is being specified in much new school construction and in many additions. While masonry maintains a strong foothold in the school construction market, that market itself is going through something of a boom. In the six years between 1989 and 1995, the amount of new nonresidential opaque wall area in the educational/science category increased from 49 million square feet to 101 million square feet. This represents a growth spurt from 7.53 percent of the total market to 13.47 percent. Masonry's ability to create an atmosphere in school interiors has been used enthusiastically by various designers. The low maintenance of brick is particularly well-suited to schools, and patterning adds visual appeal without adding cost. Patterning and color can make a school seem more approachable, less intimidating to children. Horizontal bands of color can help warm a building and restate its mass. Architects try to design a school so that it stimulates learning and symbolizes the importance of education but also is fun. In addition, masonry's fire resistance gives it a competitive edge over more flammable products. The cost of maintenance is another area where masonry does well. Less sturdy interior walls are more vulnerable to destruction and require a lot more maintenance to keep that "just constructed" look.
