Help Protect against Break-ins -San Antonio windows and doors that are upgraded with our Generations Secure glass package will help provide security protection 24 hours a day, 365 days a year. Since this tough glass can stand up to repeated blows from common burglary tools like bricks, bats, hammers and crowbars, it is backed by a $1,000 break-in protection warranty*.

Reduces Irritating Outside Noise- The plastic interlayer in our Generations Secure glass package acts as a filter that blocks out more noise than ordinary glass by as much as 50%** – resulting in a quieter and more comfortable interior environment.



*If a home owner files a an insurance claim resulting from a break-in through a KeepSafe glass window or door system, KeepSafe will pay the homeowner’s deductible up to $1,000. Warranty is transferable.

**Tests show KeepSafe glass is most effective when installed in insulated glass units with a half-inch air space and can reduce perceived noise transmission by one-half as compared to a single pane of ordinary glass.
