The arrangement of definite and planned openings in a building such as windows, doors, louvers, vents, wall panels, skylights, storefronts, curtain walls, or slope- glazed systems, as per the building functionality, is known as fenestration. The fenestration arrangement in any building helps to develop a visual connection between the indoor and outdoor environment, improves the visual appeal of the building, and influences the image and purpose of the built environment or the constructed space. Fenestration is an integral part of building design and considers various aspects such as energy efficiency, aesthetics, and eco-friendly nature of development.

Seal coating, also known as pavement sealing, is a process of applying a protective layer/coating to asphalt-based road pavements for providing a layer of protection against elements, such as water, oils, and UV damage. Seal coating protects and prolongs the life expectancy of asphalt pavement by filling surface damage and providing a protective layer to keep out damaging UV rays, vehicle fluids, and water. Apart from the above-mentioned, appearance is a big advantage of sealing an asphalt driveway. Using a sealer will ensure that the driveway looks much cleaner, with a smooth and sleek finish.
