Our jib doors are wind-resistant and vibration absorbent due to high
quality hollow inner frame construction.

Accordingly, our inner and outer frames are flexibly jointed, with
triple seals (one glue strip and two wool strips) for reliable air
and water tightness and solid functionality.

Moreover, our doors come with an oblique stepped structure and the
downward-sloped drain slide to ensure free water discharge without
any back-flow.

Our doors' corrugated glaze-window may be internally or externally
fixed in the same slide. It effectively prevents mosquitoes and flies
from entering your home.
