How is a glass-to-glass corner window different from a regular corner window?
Instead of a visible frame post at the corner, two glass panes meet directly — giving an uninterrupted, wraparound view instead of a frame line splitting it.
Which is better, inward or outward opening at the corner?
Both configurations are available; the right choice usually comes down to the room layout and how much clearance there is on either side of the corner.
Is the corner joint as weathertight as a standard window?
Yes — rubber gaskets specifically engineered for the corner joint keep sealing performance in line with a standard single-pane window.
