Otai prefabricated  accessories  are all made by polymer waterproofing membrane ( TPO, PVC or HDPE membrane) ,which are easily welded with the same waterproofing sheet with hot air .

In the process of waterproof construction, prefabricated accessories can be used to properly handle some special details, which can avoid potential leakage and greatly improve the effect and efficiency of construction.

Applicator use Otai prefabricated flashings benefit from more efficient and productive crews who aren’t spending unnecessary time creating flashings in the field. This leads to:

● More efficient crews who don’t sacrifice quality for speed

● The ability to get more work done without additional labor

● Increased revenue from additional jobs that can be completed due to time saving
