NEW
Keystone 2.0
Keystone redefines what an impact rated frame can do, with certification to a design pressure of ±65 PSF. Its lightweight uPVC construction provides lasting strength and weather resistance while eliminating the weight and finishing hassles that come with aluminum. The Keystone frame features our Grip-and-Release System (patent pending) for easy servicing with a clean, finished look, Keystone ensures confidence from installation to inspection.
STRUCTURAL PROTECTION
Understanding Impact Frames
To make sure that homes in areas affected by hurricanes and other severe weather are structurally sound and protected, the impact building code ensures building materials can withstand damage from high winds, torrential rain, and airborne debris.
IMPROVED AESTHETICS
Looks As Great As It Performs
Keystone removes unsightly screw holes with a smooth, snap-on frame cover. We’ve also improved upon the aluminum frame with welded miter corners.
We’ve upgraded to a uPVC vinyl material that uses a one-step paint process for easy finishing. This material matches the look of vinyl windows for a polished home exterior. The Keystone frame is shipped with a film protector so you don’t have to worry about scratches before installation.
For the Pros
Certified to the Highest Standard
The Keystone frame is certified to the highest standards of impact building code. It has a +/- 60 PSF rating, and is rated for High Velocity Hurricane Zones (HVHZ) and Wind-Borne Debris Region (WBDR).
Lighter & Easier to Install
The uPVC vinyl material of Keystone makes it lighter to transport and easier to install. A co-extruded seal stops debris from collecting between the frame and the glass or door. The seal is uniquely engineered to absorb the variation in door thickness and prevent paint from seeping during finishing work.
The H-Channel design allows for seamless alignment, and improves screw engagement with aligned inner and outer frames. The H-Channel centers and cushions the insulated glass (IG) without getting in the way like glass rests do, making installation a breeze.
Keystone has a compatible profile to the ODL aluminum frame, allowing for single unit replacement without a huge overhaul, something you and your customers can appreciate.
Improved Serviceability
The Keystone frame with Grip-and-Release System (patent pending) replaces permanent tape with interlocking stems for a secure fit that removes easily during servicing.
No Dow 995 application is required, yet frames are removed easily for service without damage.
