Silver Line's new Weather Stopper™ products have been tested and certified to stringent ASTM and Miami-Dade Product Control protocols to ensure they resist high velocity wind pressure and impact from windborne debris. Residential homes in coastal areas can encounter extreme weather conditions. When a storm, such as a hurricane strikes, its destructive force can be devastating. Silver Line's Weather Stopper™ line of impact resistant windows and patio doors can help protect homes from catastrophe. By combining a series of specially designed, inter-related components, we've created a line of windows that will endure the elements and help to protect the homes in which they are installed. From a unique, patented interlocking tilt latch design, to a positive action sash lock to DuPont SentryGlas®, each element of this window has been carefully selected to perform, even under the most severe conditions.
