Storm doors offer an extra layer of protection to your main entry door, helping extend its lifespan by shielding it from harsh weather. They improve energy efficiency by creating an insulating air pocket that reduces drafts and heat loss. Storm doors add natural light and ventilation through a retractable screen that's easy to use. They also enhance home security with durable materials and additional locking mechanisms! Two different locks are available - Kwikset as well as a Schlage lock that's keyable by us.
