We plan to build a house in Sedona, AZ.  We have a question about what
type of windows to install.  My questions are:
1.  Are roll out windows best, or sliding windows from left to right,
or conventional windows that raise up or down?
2.  We have beautiful views and need to install windows that do not
obstruct our view, but will give us ventilation if opened.
3.  Would it be okay to have stationery windows at the top and one of
the open style of windows at the bottom, will that let in enough air
from the outside?
4.  Which type window is best for ventilation?  Does the roll out
windows let in as much fresh air as the other windows?
5.  We would like to purchase windows that are wood inside and
alumnium outside.  We understand wood windows are very expensive. 
Does anyone know where we can get nice wood windows with aluminium on
the outside at a reasonable price?  The SW sun is hard on materials.

Thanks for your help.
