Window and Sliding Glass Door Standards
As of October 11, 2011

Following are the new window and patio door standards for HGC which covers replacement or new window/sliding glass door configurations in our Cluster.  The standards were approved by DRB on October 11, 2011.

 Overview:

Before replacing windows or sliding glass doors all residents are required to submit an application to RA as noted in the Reston Association Design Review Guidelines (www.reston.org) and obtain RA approval of the same.   Applications conforming to Cluster window and door standards can be reviewed and approved at the RA staff level.  Applications   for window and patio door replacement not conforming to the Cluster standards must be reviewed by the Design Review Board.   For more information or to submit an application contact Trevor Wright, RA Covenants Committee Coordinator, at 703-435-6563 or twright@reston.org.

Example Window Diagrams (click on the links below):

I.              Typical 6’ wide x 6’ high mullioned sliding windows:
6 x 6 Siding Windows
 
This window configuration consist of one 2-pane horizontal sliding windows mullioned (joined) on top of two 3’ wide x 2’ high stationary windows.  The drawing also shows the “glass to glass” mullioned area of a window. 

II.            Typical 9’ wide x 6’ high mullioned window:
6 x 9 Windows


This window configuration consists of 6-panel window panes mullioned (joined) together.  The top 3 panes are each 3’ wide x 4’ high; the bottom 3 panes are each 3’ wide x 2’ high. Typically the middle top pane slides right or left.  The remaining panes are stationary.
