● Benefits
Why ViewFlex Vinyl Outperforms Glass for Porch Windows
All WeatherMaster window systems use ViewFlex vinyl glazing instead of glass. For homeowners used to glass windows, the difference matters before making a decision on porch window installation:
More Durable than Glass
ViewFlex vinyl resists shattering or cracking upon impact, offering a safer option for porches where contact is common from furniture or weather.
Better Thermal Conductivity than Single-pane Glass
ViewFlex retains warmth more effectively in the shoulder seasons, thereby extending the comfortable use of your porch or screen room.
Lighter and Easier to Operate
Individual vents can be lifted out by a single person for easy seasonal storage or cleaning, a significant advantage over glass.
UV Protection Built in
All four tint options block harmful UV rays, protecting your furniture and flooring without requiring a separate window treatment.
Virtually Maintenance-free
Our new windows eliminate the need for painting, sealing, or re-glazing, offering you a durable, maintenance-free solution for your home.
Time-tested Durability
With over 40 years of time-tested durability, this product excels in outdoor applications across North America.
