• Double or Triple Glazing: Inert gases like Argon are often utilized between panes to slow down heat transfer.
• Low-E Glass: A microscopic finish shows heat back into the space.
• Weather Stripping: High-quality brush seals prevent drafts from entering the sliding mechanism.

Security Features

Modern sliding windows are no longer the security danger they when were. Most systems now include:

• Key-Locking Sash Fasteners: Central locks that protect the 2 sashes together.
