Longevity

We expect our products to live well past their warranty period. But kids still throw baseballs and even the most durable materials can wear out eventually. That’s why we can provide replacement parts for our windows and doors, even ones that were discontinued 50 years ago. Visit our Parts Catalog for a detailed list of what’s available.

 

To make sure that our windows and doors last* we put them through testing in the lab and the field that few other windows endure. Some are exposed to wind speeds up to 155 MPH. Others face sudden temperature changes from -20°F to 180°F.
