Test for confirming waterproof performance
Left: Type Z,
Right: Type Z-WR
Two specimens of Tiger Board Type Z-WR and Tiger Board Type Z (regular fire resistant gypsum board) were allowed to be permeated by ink water at 1 cm of their lowermost edge for an hour to check the waterproof performance of each specimen.
It was observed that the Tiger Board Type Z-WR mostly did not suck up the ink water, therefore confirming that it has a high level of waterproof performance.
Advantage② Highly durable exterior wall that protects your residence
The ventilation construction method improves the durability of the building.
By using antimildew agent in addition to the high-level of waterproof performance, Tiger Board Type Z-WR also has resistance against mold.
(However, it does not guarantee that mold does not occur at all.)
