Special Layers

Double UV polycarbonate sheets: These polycarbonate sheets have UV protection on both sides for a superior resistance, which help keeping a high light transmission for more time, it also has cut and installation advantages.

Frosty Glass polycarbonate sheets: These polycarbonate sheets have a frosted glass appearance that provides greater light diffusion.


Macrolux Rooflite polycarbonate sheets are made for an easy and simple installation. On horizontal applications, the installation has a better result if it is fixed through the material’s crest. (Figure 1 y 2).

When joining the sheets, it is important to overlap one of the ripples, allowing the upper polycarbonate sheet to be up hill. (Figure 1)

For vertical installations it should be fixed through the valleys (Figure 3). It is recommended to firmly fix every third ripple, and on every second ripple on the crest and groove. Union elements should be fixed without using excessive tension (space for expansion) because it may damage the polycarbonate sheet. Later, place neutral base alcohol sealant on each washer (Figure 4).

It is recommended that the separation between joists be of 90 cms from the edge of the crest and furrow and 1.22 mts to the center of the stretch.

Assure that the polycarbonate sheet is well fixed before cutting it to avoid vibrations, the cut should be made with scissors, circular saw or fine-tooth razor.


When the installation is finished, it is recommended to wash the sheets with neutral soap and warm water, using a sponge or soft and clean cloth, and rinse with water.


It is recommended to storage the polycarbonate sheets stacked on an even surface, free from direct contact with sunlight or heat.
