About Roof Materials

Roof Materials

Polycarbonate

brown smoke/blue smoke/clear mat
clear

Cut out UV rays 100% and has a strong impact resistance 250 times higher than glass. Since it does not harden at low temperatures, it is suitable for use in cold climates.

Heat protection polycarbonate

blue smoke
KRBS,YFA-series
blue smoke
Sun side view/Ground side view

When looking from the sun side , the surface reflects in sunlight, therefore the color of the panel looks different from the ground side view.

FRP

clear(emboss)

Adopting direct rays of the sun as kind airlight by making emboss-texture on the FRP board which is superior in strength / weatherability. There is a good for blindfold effect. (Cut out UV rays 100%)

Heat protection FRP

clear(emboss)
clear(mat)

Having same features and specification of FRP board and reducing the heat energy through it. There are emboss-texture on the ground side. (Cut out UV rays 100%)

Aluminium/resin composite panel

ivory white

For the opaque material which is higher advantage for fire prevention and impact resistance, The roof panel completely cuts UV Rays and Heat Rays.

Graph1: Dispersed ray transmittance curve

The sun's rays are classified into ultraviolet rays, visible ultraviolet rays, infrared rays etc. as shown in the wavelength in Fig. 1.
Near-infrared rays called heat rays, equivalent to about half of the entire solar radiation energy from sun beams, can cause damage to objects.
Heat protection polycarbonate sheet finished with a special mixture can restrict the sun's rays in this range more effectively compared with general polycarbonate sheet (See graph).
With this function, the solar radiation energy can be drastically reduced.
