Most solid plastic toilet partitions are one inch thick, however because polypropylene solid plastic is more rigid than high-density polyethylene, (HDPE), three-quarter-inch thick doors and panels can be used as well. These lighter, solid plastic panels are more manageable than traditionally specified solid plastic and plastic laminate panels.

Solid materials, such as polypropylene, have many advantages over other materials because they are more rigid, will not dent or crack, and never need repainting. The internal structure of the panel is made to take potential abuse from denting or lateral forces. Scratching has been considered by using new techniques to powder coat metals, brushed metal surfaces, and solid, composite or plastic laminate surfaces. Textured steel panels hide fingerprints, and offer improved acoustic qualities.

The use of brushed metal surfaces for toilet partition panels is preferred where scuffing or marking the surface is a concern in high-traffic areas. Embossed and textured stainless-steel partitions are generally available, along with a range of basic color choices and finishes. Architects can specify a metal powder-coated finish on steel toilet partitions because of the affordability, strength of the steel, and durable quality of the finish. Attached metal splash plates and grab bars are used with every type of toilet-partition material available. Plastic panels do not have the sound absorption qualities that textured steel panels provide.

For large exposed surface areas, cleaning graffiti can be a large percentage of personnel and maintenance supply budgets. A polypropylene solid plastic surface typically does not leave ghosting after cleaners are used. Advances in powder-coating technology include finishes with anti-graffiti properties.

Sustainable Design: Using Reclaimed Materials

Many materials are eligible for Leadership in Energy and Environmental Design (LEED) ratings, as developed by the U.S. Green Building Council (USGBC), but not all toilet partitions meet sustainability goals. The LEED Green Building Rating System® is a voluntary, consensus-based national standard for developing high-performance, sustainable buildings. Recycling is an area of manufacturing addressing the use of environmentally sensitive or sustainable design.

Some, but not all, toilet partitions offer recycled content in doors, panels, and pilasters. Architects should carefully investigate material content of building products when specifying or considering sustainability ratings, because the details can vary considerably. Researching materials and processes will determine whether certain toilet partitions are eligible to earn LEED points, which contribute to a building's overall rating.

For example, some available powder-coated metal toilet partitions and screens are manufactured from material containing approximately 50 percent recycled steel (36 percent post-commercial, and 14 percent post-industrial). Other stainless-steel toilet partitions typically contain approximately 75 percent recycled stainless steel. The honeycomb core of some partition doors, panels, and pilasters is composed of 18 to 24 percent recycled content.

Similarly, some available solid plastic toilet partitions are made from marine-grade polypropylene, an environmentally responsible choice. The post-industrial content for these types of partitions ranges from one percent to 10 percent, and the long lifespan of plastic equates to less material used over the long term, due to minimal replacement needs. Widely used, powder paints are safe on the environment, as there is virtually no waste, energy consumption is low, and there are no solvent emissions in the painting process.

A green, or sustainable, building should maintain a balance with the natural environment, including indoor air quality. The use of composite recycled materials provides durability and maintenance solutions in high-traffic areas. Many types of panels can last as long as 20 years, thus minimizing replacement and enhancing sustainability. A long product life span means systems are replaced less often, and therefore less material will be used over time.

As the leading organization representing the industry on environmental building matters, USGBC advocates changes in the way buildings are designed, built, and maintained. Similar types of building products, including toilet partitions, can vary widely regarding materials, content, manufacturing processes, and other sustainable qualities, which all must be carefully investigated before specifying. Architects can access the certification process through the USGBC and local affiliates for sustainable design standards. (www.usgbc.org)
