Like
most other Vantage doors Duo Sliders can be fitted with
fixed or awning highlights to allow ventilation without
sacrificing security. On wide doors this transom strength
may become the weak link.
The
best of both worlds a large door that lets in light and sun,
with secure opening highlights for ventilation.
Both doors and highlights can be double glazed for thermal control
in cold climate areas.
Large
Openings
Both
three panel and six stacking panel doors give very
large openings (over 60%) as illustrated right.
If you are looking for a door for your entertainment area this
could be the product.
