Simonton and PGT Impact Replacement Window types.

Impact Double Hung Windows

Double Hung Replacement Windows Karoly Windows and Doors Clearwater Palm Harbor Largo Tampa St Petersburg

Simonton offers double-hung windows as the baseline in their StormBreaker Plus product line. These impact windows are convenient opening from the top and the bottom sash with a moving half-screen. This is for more window utilization, more light, easy cleaning, and better service.

The most important feature of the impact windows from Simonton is the modular approach to their windows. If your window ever needs a warranty replacement, they provide an entire sash which we easily replace. We coordinate the warranty claim for you and replace the sash for you when it arrives.


Impact Single Hung Windows

PGT offers single-hung windows as their baseline in the WinGuard Vinyl product line. These impact windows only open from the bottom sash. They come standard with a constant force balance system for easy operation.

Impact single-hung and slider PGT windows have fixed glass. Under a glass warranty claim, PGT will provide the replacement glass (40-100 lbs glass). You are required to hire a glass professional to properly replace the glass (cost typically between $450 and $1000) or use the PGT service technician (~$175/hour) to replace any defective glass.
