Impact Resistance
Marklon Hollow Sheet is stronger impact than regular
glass and acrylic. Due to this feature, maintenance
and glazing replacement costs are minimized.
|
| |
| 2. |
UV Resistance
Using advanced co-extruded method, Marklon sheet is
UV coated one side. This make it longer lasting against
weather ability.

High Degree of Transparency and Thermal Insulation
Marklon's polycarbonate clear sheet is as transparent
as glass. It also insulates better than single-pane
glass. Double-glazing or over-glazing on windows, walkway
or overhead bridge can save on energy cost.
