Water – The Real Enemy!
Did you know that most of the damages caused to homes from storms is due to water? If a tree limb breaks through your window it will certainly cause a mess, but more critically your home is now open to wind-blown rain that can permanently damage floors, furniture and other personal belongings. It also opens your home to an opportunistic burglar.
This is one of the most important benefits of a certified Impact Window like Safe Harbor. The laminate glass is tested to not break through even if struck by significant force like a wind-blown limb. So water doesn’t get in and cause irreparable damage to your personal belongings. And the opportunistic burglar is simply out of luck!
Anatomy of a Hurricane Impact Window
To be certified as an Impact Window meeting hurricane wind standards, a window must meet specific requirements established by the Texas Department of Insurance (TDI). TDI has defined a number of ‘zones’ which have different requirements, from basic wind-loads up to full impact window. The two key requirements include:
Design Pressure ratings (DP)
Most windows are tested and receive a DP rating. This rating communicates both a structural wind speed test and a test for leakage with wind-blown water. TDI has defined areas where windows must meet certain minimum DP levels in order to be installed and the installation must be done differently as well. Some windows will not meet these requirements and, even more importantly, many installers are not trained for proper installation! Custom Windows can help you understand the requirements for your home and has the trained installers to ensure your windows meet TDI installation requirements, too.
In cities along the coast, TDI certified Impact Windows (or commonly called hurricane windows) must be used. These use a special laminate glass as well as structural reinforcements to the window which have been tested to withstand remarkable impacts without breaking through the glass or the window frame itself.
All Safe Harbor windows meet the toughest DP and Impact standards and are TDI approve for every zone. And many other windows from Custom Windows will also meet many zones which only have DP requirements but do not require impact certification.
