What types of materials are typically used for window weatherstripping?

Window weatherstripping is designed to prevent air leaks and improve energy efficiency by sealing gaps around windows. Common materials used for this purpose include foam plastic, which is effective in creating a tight seal; metal, often used for its durability and resistance to wear; and various forms of plastic stripping, which can be molded to fit different window designs and provide reliable insulation.

Foam plastic offers flexibility and is easy to install, making it popular among homeowners and professionals alike. Metal strips provide a sturdy option that can withstand various weather conditions without degrading. The combination of these materials ensures long-lasting performance and efficient sealing.

The other materials listed in the other answer options do not typically meet the effectiveness or suitability criteria for weatherstripping. For example, while wood is a common construction material, it is less effective in providing a flexible, durable seal compared to foam or plastic. Glass is not used for weatherstripping due to its rigidity and fragility, and options like paper do not offer the necessary durability or weather resistance.
