Sealing solutions designed for double casement openings enhance energy efficiency and comfort by closing gaps between the door panels and their frames. These products typically consist of compressible materials like foam, rubber, or felt, and may be affixed with adhesive backing or inserted into channels within the door frame. Specific designs are available for different door styles and frame materials.
Effective gap closure around exterior openings significantly reduces drafts, minimizes heat transfer, and can improve sound insulation. This contributes to lower energy bills, increased indoor comfort throughout the year, and a quieter living environment. Historically, simple materials like felt or fabric were used to seal gaps. Modern materials offer superior durability, resilience to weather, and effectiveness.
