Twin Wall Polycarbonate panels offer excellent insulation because of its ribbed configuration of the multi-walled sheets that trap air within the sheet, providing outstanding thermal insulation. Twin Wall Polycarbonate sheets are ideal for applications where specific light transmission is required.
This material has an impact strength 200 times greater than glass and 8 times greater than acrylic. It is 1/6 the weight of glass and 1/3 the weight of acrylic. Twin Wall Polycarbonate is compliant with most international standards for flame resistance, at very high temperatures, material melts but flames do not spread. This material will not crack or split when cut, sawn or drilled. Solar grade co-extruded layer protects the sheet against yellowing and surface wear from extruded UV exposure.
Twin Wall Polycarbonate sheets are designed for an endless range of glazing and roofing applications, for extreme weather conditions, and are known for their light-transmitting and reflective qualities. They are attractive, durable, easy to install and protect people and property inside a structure from the elements and from damaging UV radiation.
Polycarbonate Profiles
Our interconnecting polycarbonate profiles connect consecutive multi-wall sheets to cover large areas. They are UV-resistant, unobtrusive and offer secure snap-fit connections. Polycarbonate profiles are available in 12 foot and 24 foot lengths. Emco carries a variety of gasket clips, ECP 2G clips, H-Clips, H-Profiles, and U-Shape Edge Profiles. Polycarbonate profiles are suitable for basic roofing applications and interior design.
Corrugated polycarbonate is a single layer sheet characterized by either a wave or box-type profile, similar in design to metal roofing sheets with “peaks and valleys”. Multiwall polycarbonate is characterized by a rectangular hollow structure “flutes” that run the length of the sheet. Multiwall sheets are fabricated in many configurations such as twin-wall, three-wall, five-wall, and five-wall x-structure.
Using multiwall or "twin wall" polycarbonate vs. corrugated polycarbonate varies greatly on what climate you're in, the style of greenhouse and if the greenhouse is used year-round. Both products are lightweight, UV protected, easy to work with and durable. Corrugated panels are less expensive but offer less heat retention. If more insulation is needed, multiwall panels are the preferred material.
We recommend using warm water with a mild household detergent. This should be sufficient to clean the sheets. Wipe off any remaining dirt with a soft cloth and wash again. NEVER use a solvent-based cleaner. AVOID using sponges or brushes that can scratch the surface of the sheet.
