BUILT STRONG
With Cornerstone there’s no need to sacrifice aesthetics for performance. Our windows are designed to enhance the look of your home and keep it safe from the elements.
- The 3¼” 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.
- Every corner of a Cornerstone window is precision fusion welded; no screws or silicone.
- 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 weather conditions.
- The vertical sill interlock and the high performance compression seal with barrier flap provide structural strength and protection against air and water infiltration.
VANGUARD LOCK
The Vanguard Advanced composite cam lock is designed to provide maximum protection from forced entry and to seal the window tighter as it locks. These American made composite locks contain no zinc or lead. The marine grade composite material has been shown to be superior to metals in strength, impact resistance, and corrosion resistance. The sloped cam pulls the sashes together and also forces the sash downward to compress the seal against the sill.
DURAFORCE BALANCE SYSTEM
DuraForce is a balance system made up of tempered, stainless steel, self-adjusting, coil springs that effortlessly support the sash. This system is maintenance free and ensures extremely smooth, quiet operation for a lifetime.

SMART GLASS
Since over 80% of your window is glass, it makes sense to select the highest performing glass that will provide you the best value in your home. Not all Low-E glass performs equally. You need glass that is smart enough to block what you don’t want and allow what you do want into your home. Our spectrally selective soft coat Low-E glass provides maximum protection to your home in winter and summer.
Smart Low-E
Our Solar Smart (SS) Low-E uses 3 microscopic layers of silver to maximize the energy efficiency of your window. SS Low-E glass reduces heat gain by 64% compared to ordinary glass and blocks 95% of harmful UV rays.
Argon Gas
Argon is a non-toxic, odorless, inert gas that is heavier than air. It provides superior insulation value when used inside an insulated glass unit. All windows with Smart Glass come standard with Argon fill.
Smart Spacer Systems
Our warm edge Intercept spacer system creates a thermal barrier between the inside and outside pane. The steel U-channel design is wrapped in butyl, preventing glass to metal contact, thus reducing the possibility of temperature transfer from one pane to the other.
Our structural foam SuperSpacer creates the best thermal barrier between glass panes. Because the material is non-metal, it virtually stops the transfer of temperature from outside pane to inside pane. This closed cell polymer foam spacer provides improved condensation resistance.
