Fiberglass doors are highly resistant to water and moisture, making them effectively waterproof. The inherent properties of fiberglass, which is a non-porous material, contribute to its ability to resist water absorption. Unlike wood doors that can swell, warp, or rot when exposed to moisture, fiberglass doors maintain their shape and structural integrity in wet conditions.
The resistance to water makes fiberglass doors a suitable choice for exterior applications, including entry doors and doors in areas where exposure to rain, snow, or humidity is common. However, it’s essential to note that while fiberglass doors are highly water-resistant, the overall waterproofing of a door system also depends on proper installation, including the quality of seals, weatherstripping, and thresholds.
For optimal performance, homeowners should follow the manufacturer’s recommendations for installation and maintenance. Regular inspection and upkeep of the door’s weatherstripping and seals will help ensure that the door continues to provide effective protection against water infiltration.
