What materials are pet doors made of?

Pet doors are typically made of durable and weather-resistant materials, ensuring longevity and security for your furry friends. The materials commonly used include high-quality plastics like polypropylene or polyvinyl chloride (PVC), which are known for their strength and resistance to extreme temperatures. These materials are often reinforced with UV stabilizers to prevent color fading and warping from sun exposure. Additionally, some pet doors feature aluminum frames that are lightweight yet sturdy. The flaps are usually made of flexible and transparent materials such as vinyl or thermoplastic, allowing pets easy access while maintaining insulation. Some advanced models even offer energy-efficient insulation through multi-layered or magnetically sealed flaps. Pet doors can be found in various sizes and designs, catering to different pet breeds and installation locations.
