1.The 3-1/4" multi-chambered frame provides superior strength, rigidity, and durability. The added depth allows the face of the frame to be
narrower, which lets more natural light into your home.
2. Every corner of a Cornerstone window is precision fusion welded: no screws or silicone.
3. The high performance true-sloped sill directs water away from the window naturally, while the auxiliary water evacuation route provides extra protection during the harshest conditions.
4. The vertical sill interlock and the high-performance compression seal with barrier flap provide structural strength and protection against air and water infiltration.
