First, they are lightweight yet strong. Fiberglass profiles feature a hollow-core design with a relative density of approximately 1.8; their tensile strength rivals that of ordinary carbon steel, and they exhibit excellent flexural strength and elasticity, eliminating the need for steel reinforcement and thereby reducing manufacturing costs.
Second, they offer superior sealing, energy efficiency, and thermal insulation. During assembly, all gaps in fiberglass doors and windows are sealed with rubber strips and weatherstripping, ensuring excellent airtightness. Additionally, the thermal conductivity of fiberglass profiles is extremely low-only 1/1000 to 1/100 that of metal-and the unique hollow-core structure further enhances thermal insulation performance.
When purchasing, consider key performance indicators such as thermal insulation (heat transfer coefficient), wind load resistance, airtightness, watertightness, and sound insulation capabilities.
Proper maintenance involves regular cleaning, avoiding corrosive cleaning agents, promptly clearing debris from gaps, operating the units gently, and conducting routine inspections to extend their service life.
