The George W. Trapp Company has been around since 1930. That means we know of or have heard about almost every single thing that ruins screens. Since screens are not covered under our lifetime warranty we wanted to make sure our customers had a choice. That is why we offer two wonderful screen upgrade options from Phifer®. Phifer PetScreen® is a great option if you have pets as it is manufactured to be seven times stronger than regular insect screening. Or, if you don't have pets and want to maximize your viewing pleasure through your Trapp® Storm Door try the Phifer BetterVue‚® Insect Screen. This screen option was designed specifically to maximize your view by making it sharper and more brilliant. The choice is up to you when you order your new Trapp® Storm Door and want to upgrade your screen.
