1) Wind-resistance and vibration absorbing: the straight materials
on the inner frame are of hollow design and have good wind-resistance
and vibration absorbing properties.
2) The inner and outer frame is flexibly jointed, and triple seals are
used (one glue strip and two wool strips). This renders the windows
with excellent air- and water-tightness and ensures they can be freely
and silently slid.
3) The oblique stepped structure and the drain in the downward slide ensure
free water discharge without any back-flow.
4) The hollow glass structure in the windows renders excellent sound- and
thermal-insulation, meeting state requirements on environmental
protection and energy saving.
5) The window is provided with thief-proof, airflow barring, loose-proof
units and unique multi-point locks, and thus keeps stable, tight and
safe.
6) Has an elegant style, streamlined design and outstanding decorative
effects.
7) The corrugated glaze-window may be internally or externally fixed in a
same slide. It effectively prevents mosquitoes and flies, has excellent
tightness and decorative effects and is especially suitable for high-
mosquito regions.
8) The unique design saves materials and costs, reduces the weight and
makes fabrication much easier.
9) Tested by the Fujian Architectural Doors, Windows & Curtains Quality
Supervision and Inspection Station. The product's, 'three performances'
were evaluated as being of grade A1 standard.
