This type of seal, characterized by its cross-sectional resemblance to the letter “T,” is commonly employed to block drafts and prevent the ingress of moisture, dust, and insects around doors and windows. It is typically manufactured from flexible materials like rubber, silicone, or foam, allowing for a snug fit against uneven surfaces.
Effective sealing plays a vital role in maintaining comfortable indoor temperatures, reducing energy consumption associated with heating and cooling, and protecting against property damage caused by moisture infiltration. The development of specialized sealing solutions, like this particular design, reflects an ongoing effort to improve building efficiency and resilience. Historically, less sophisticated methods were used, often relying on rudimentary materials like felt or cloth, which offered limited protection against the elements.
