Glossary of Terms

quick guide to interpreting modular-speak

A - E

Air Plenum

An air-filled space in a structure that receives air from a blower for distribution (as in a ventilation system). It forces dirty air through the plenum through a HEPA or ULPA filter scrubbing particulates and redirecting clean air into a working room.

Airport Walls

McCain Walls are reconfigurable to meet any airport project spec - new baggage carousel, terminal renovations, restroom improvements, that require temporary or permanent walls or enclosures. The airport walls are flexible and versatile, providing endless configuration options with an array of doors, variable angle panels, windows, and more.


Common construction material that is thought of as one of the most sustainable and energy-efficient construction materials for green build.

Architectural Decorative Panels

Custom decorative panels manufactured from aluminum material and powder coated or "skinned" to give a distinct high-end look. Generally used to add beauty or amplify decorative design in a commercial and residential space. Comes in various colors, sizes and designs.


A transportation device that moves building materials and product easily between job locations. McCain Walls transporation carts are designed to store modular wall panels when they are not in use.

Casino Walls

Casino walls are the ideal solution to secure, pristine walls that provide instant barricades, protecting patrons from hazardous construction areas, with very minimal interruption to the hotel and casino operations.


A room for the manufacture or assembly of objects (such as precision parts) that is maintained at a high level of cleanliness by special means.

Door Kits

Single and double doors designed specifically for McCain Walls reusable and modular wall sytems, available in inswing and outswing configurations. Commercial-lever locksets are the standard locks, however, various lock options are available depending on the project requirements.

Emergency Board Ups

Temporary walls and barricades minimize potential water damage prior to a storm or can add additional security to a business after a sudden disaster such as a floor or fire happens. Emergency board up interlocking panels are manufactured from 0.90 thk aluminum and powder coated with a commercial-grade finish that does not capture moisture, eliminating the worry of mold grown on temporary wall partitions.

F - L

Green Living

A lifestyle that tries to incorporate both conservation and preservation of our planet through actions that reduce any negative impact to our environment.

HEPA Filters

HEPA filters, as defined by the United States Department of Energy (DOE) standard adopted by most American industries, remove at least 99.97% of airborne particles 0.3 micrometers (µm) in diameter. The filter's minimal resistance to airflow, or pressure drop, is usually specified around 300 pascals (0.044 psi) at its nominal volumetric flow rate.

Hospital Walls

McCain Walls anti-microbial, reusable, modular wall systems are easy to clean and maintain with wipeable powder-coated surfaces, supporting construction-related infectious control plans. One- and two-sided hospital walls provide reconfigurable partitions that keep patients and staff from hazardous construction areas.

Horizontal Sliding Panel (HSP)

Adjustable wall panel with a 7” travel span. The horizontal sliding panel can expand up to 30” in length, decreasing gap tolerances between the last panel and ending point.

M -S


A micron is a millionth of a meter. To compare, a human hair is about 100 microns wide.

Modular Enclosures

Modular enclosures are prefabricated off-site in a manufacturing facility and then delivered to an intended site of use. It can be temporary or permanent structure and usually made with more sustainable materials than traditional buildings. Modular enclosures can be configured into private rooms, offices, clean rooms, anterooms, and such.

One-Sided Wall Systems

Reusable modular walls designed to provide protection from hazardous construction areas or isolate private sections of an area. One-sided walls have a smooth powder coat finish on the public side that lends itself to graphics applications such as wraps, vinyl lettering and such. One-sided systems can be used for temporary and permanent use.

Particulate Matter

Particulate matter (PM), also known as particle pollution, is a complex mixture of extremely small particles and liquid droplets that get into the air. Once inhaled, these particles can affect the heart and lungs and cause serious health effects.Particulate matter (PM) is contamination in the air, or contamination generated by a process.


Also known as dividers, are built to create seperations in a room or large open space.


The process of recycling products and material helps eliminate waste from filling up the landfills, turning it into other recyclable products. Best recycled practices leads to a healthier planet.

Recyclable Material

Recyclable material include many kinds of glass, paper, and cardboard, metal, plastic, tires, textiles, and electronics. The composting or other reuse of biodegradable waste—such as food or garden waste—is also considered recycling.[4] Materials to be recycled are either brought to a collection center or picked up from the curbside, then sorted, cleaned, and reprocessed into new materials destined for manufacturing.

Recycled Material

All types of materials, both man-made and grown from the planet are then reconstructed into another material or object to be used again and not left in the landfills or pollute the planet.

Sticky Mat

A sticky mat is a special mat at the entrance to a clean room with an adhesive coating that removes dirt and other particles from shoes.

Sustainable Material

Products or materials specifically designed to provide environmental, social and economic benefits while protecting public health and environment from beginning to end

T - Z

Trim Caps

Top trim caps are designed to fill the irregular gaps between the top of a McCain Walls system and an existing ceiling, for a seamless finished look.

Two-Sided Interior Walls

Two-sided interior walls provide smooth powder coat finishes on both sides of a wall system. These can be retrofitted to accommodate light switches, electrical outlets, and flat screen TV mounts. Architectural decorative panels can be added to create a distinct custom environment.

Variable Angle Panel

Adjustable corners provide non-90 degree angles. The interchangeable clamp mechanism in the variable angle panel offers 90 - 180 and 180 - 270-degree corners ideal for curved walls
