ACRYLITE® Resist Diffuse High-Impact Acrylic

Product Information

4011 pic 14011 pic 2


This material is a light transmitting, heat-insulating, and weather-resistant sheet made of impact-modified acrylic (polymethyl methacrylate, PMMA) polymer.

This 16 mm multi-skin acrylic sheet is now available with diffusion properties, and ideal for commercial greenhouse applications where diffused light is desirable for optimized crop growth, while maintaining overall high light levels.

It scatters light, achieving a more homogenous light distribution that penetrates deeply into the plant canopy, wrapping plants in light and activating more photosynthesis. This translates to fewer hot spots, fewer shady spots, better growth, stronger plants, and brighter colors.

This new sheet provides increased light into the greenhouse in morning and evening despite the low angle of light, and helps greenhouse temperatures during summer months, reducing the need for shade cloth.

As with all ACRYLITE® Resist high-impact multi-skin sheets, this product offers the additional advantages of:

  • UV-resistance with a 30-year warranty against yellowing
  • Non-toxic biologically neutral Anti-Algae Application
  • Excellent protection against excessive amounts of UV radiation
  • Up to 50% energy savings and minimizes CO2 emissions
  • Hail-resistant with a 10-year guarantee for withstanding hailstones with a kinetic energy of 1 joule
  • High light transmission in the PAR and visible spectral energy wavelengths
  • Impact resistance during transportation, handling and installation
