## Description

This double-layer insulating side panel kit is designed to seal the gap between a window-mounted air conditioner and the window frame, helping maintain consistent indoor temperatures year-round. It works by minimizing airflow leakage around the unit, which supports better climate control and reduces energy waste. The panels are made from durable, heat-resistant material with an 80% shading rate and built-in wind and dust resistance. Each panel features self-adhesive side channels for secure attachment and can be trimmed to fit various window configurations. The kit includes 2 side panels, one roll of insulating tape, and an instruction sheet. It accommodates most standard window AC units rated between 5000 and 20000 BTU. Installation requires simple measuring and cutting before applying the panels to the window frame edges. No tools or permanent modifications are needed, and the design supports both clip-on and flat-type mounting styles.

• Blocks airflow gaps between AC unit and window frame
• Made of heat-resistant material for durability
• Self-adhesive side channels ensure secure attachment
