In addition to thermal insulation, the rubber piece serves to minimize noise pollution. Homes and offices are often filled with various sounds that can be disruptive. The rubber strip acts as a barrier, dampening sound waves that would otherwise travel freely under the door. This is especially beneficial in offices where privacy is a concern or in residential settings where noise from kids, pets, or outside traffic can be distracting. By absorbing sound vibrations, the rubber piece helps to create a quieter and more peaceful environment.

1. Energy Efficiency One of the primary benefits of installing thick weather strips is the improvement in energy efficiency. By sealing gaps and leaks, these strips prevent heated or cooled air from escaping, allowing your HVAC system to work more efficiently. This can lead to significant savings on utility bills, especially during extreme weather conditions.
