IQ-Relax polycarbonate sheets for additional heat reduction

These polycarbonate sheets are specially developed to decrease indoors heat. It has advanced solar control properties that automatically adapt to weather conditions: lets in natural light, preventing the entry and exit of most of the heat and cold. A thermal reduction of 13°C has been proven, against standard polycarbonate sheets of the same thickness. Macrolux IQ-Relax contributes to environmental sustainability and obtaining LEED credits.

No-Drop polycarbonate sheets for humidity conditions

These polycarbonate sheets have a special layer for water dissipation that prevents droplet formation on humid conditions, typically found in greenhouses.

Double UV polycarbonate sheets for a superior resistance

These polycarbonate sheets have UV protection on both sides for a superior weather resistance, which helps keeping a high light transmission for long time and provide advantages of cut and installation.

Frosty glass polycarbonate sheets for better natural light diffusion

Presents a frosted glass appearance on polycarbonate sheets, providing better light diffusion and differentiated aesthetic finish.

Deformation by load

When the Macrolux Multiwall polycarbonate sheet (cellular polycarbonate) is used, forces applied by the wind and snow loads should be absorbed by an adequate structure. Besides, closing devices should be used to protect the complete structure (PC sheet and metal or wood structure) against the wind suction.

Anticipated structural load values are specified in the local construction regulations. The total applicable load deforms the sheet. For aesthetical and security reasons the maximum stooping should be limited to 5% of the shortest side dimensions of the sheet.

Expansion by heat

Macrolux Multiwall polycarbonate sheets (cellular polycarbonate), has a heat expansion coefficient higher than standard construction materials, as glass, steel and aluminum. Specific distance between the sheet and the structural frame should be calculated to guarantee a correct installation.

  • To avoid condensation in the cells of the polycarbonate sheets and its deterioration, always keep them with the cells in a vertical direction.
  • Always store the polycarbonate sheets horizontally, never against the floor. Apply aluminum tape to seal the cells after cutting the sheet. Do not walk on top of the sheets.
  • Do not apply load directly to the polycarbonate sheet with the foot or knee. Use wood platforms or supports to distribute the pressure during installation.
  • Remove the protective film right after having installed it; never do it before the installation.
  • Macrolux polycarbonate sheets can be cut using tools for standard materials, such as knives and cutting blades. Nevertheless, the use of a table with fixed blades is recommended for cleaner cuts.
  • It is not recommended to drill the polycarbonate sheet. Instead it is recommended to use aluminum or polycarbonate profiles to fix the sheets to the structure.
  • Never use PVC profiles when installing Macrolux polycarbonate sheets.


  • For general cleaning, the use of water and neutral non-abrasive soap, solvent-free is recommended.
  • Rinse with pressurized water. Use soft cloth or sponge to remove any dirt or grime residue. Never use abrasive cleaners or brushes. Do not scrub the surface of the polycarbonate sheet.
  • Never clean with gasoline, benzene or acetone.


The use of perimeter sealant base on silicone such as DOW Corning-791 or equivalent is recommended.
