Sold primarily in large panels, acrylic twinwall is a sturdy, two-panel sheet of acrylic commonly used in greenhouses and other outdoor structures requiring sunlight and UV protection. The two panels are affixed to one another by way of perpendicular strips of acrylic that create open-air channels throughout the material. The unique design allows for added stability, durability, and insulation. The individual channels inside the panels also allow for insulated piping should your project require it.
Unlike single-panel acrylics which have degrees of flexibility and give, twinwall acrylic panels are designed to maintain structural integrity and withstand the elements. In terms of acrylic twinwall distribution and sales, panels are sold mostly in 4’x8’ sheets, but can be cut to size fairly easily. Twinwall sheets are available in a variety of thicknesses, grades, colors, and tints. And aesthetics aside, each variation comes with its own advantages depending on the application for which it’s being used. If you aren’t sure which style of twinwall is best for your project, you’ll want to consult with one of our acrylic twinwall fabricators and plastics experts.
Twinwall panels are produced through a technique known as “extrusion” through which melted thermoplastic is forced into a mold, hardened, extracted, and cut to size. Generally, twinwall panels can be installed or added to a project fairly easily with the right tools and installation accessories. Of course more complex endeavors may require professional assistance.
