Sealing exterior wooden doors against the elements involves attaching thin strips of flexible materialtypically rubber, silicone, felt, or foamto the door frame. This creates a barrier against drafts, moisture, and pests. For instance, a foam strip might be placed along the bottom of a door to block airflow, while adhesive-backed rubber could seal gaps around the sides and top.
Effective sealing significantly improves energy efficiency by reducing heat loss in winter and heat gain in summer, leading to lower energy bills. It also enhances indoor comfort by minimizing drafts and preventing outside air, dust, and insects from entering. Historically, various materials like felt and animal hides were employed for this purpose. Modern materials offer improved durability, resistance to temperature fluctuations, and easier installation.
