GBI offers preassembled windows without a frame and put together using our Power Flex Silicone. (Click here for Safety Data Sheet on our silicone.)
All you have to do is call in your size and we will make up your panel as close to your opening as possible. The difference in size gets framed in or mortared in. Lead time is about 4 business days and we keep a vast array of sizes already in stock. Best of all you eliminate mortar joints and receive a stronger, more durable window. In fact it takes 375 pounds per square inch to break apart a Power Flex Panel.
*Windows can be built up to 128 UI in one section. After a 64 x 64, it is recommended to use mortar with reinforcement.*

GBI offers a pre-fab ready to install vinyl window that comes in white or tan with a nailing flange. Just simply call us with your opening and we will make the window close to your window fitting and all you have to do is nail it. This saves time, and it is better insulating than traditional mortar.
*Windows can only be built up to 128 UI.*
