What are the Features of New Fiberglass Doors?

Choosing the right door for your home can be challenging with numerous options available. Among these, fiberglass doors stand out due to their numerous advantages. Here’s an in-depth look at the features that make fiberglass doors a great choice.

Lightweight and High Strength

Fiberglass profiles have a density of about 1.7, making them 4 to 5 times lighter than steel but very strong. Their tensile strength ranges from 350 to 450 MPa, comparable to that of ordinary carbon steel. With a bending strength of 388 MPa and a bending elastic modulus of 20900 MPa, fiberglass doors require steel lining for reinforcement. Tests show that fiberglass windows can withstand wind pressure resistance of up to 5.3Kpa, exceeding the level 8 standard of the international GB/T7106-2002.

Energy Saving and Heat Preservation

Fiberglass profiles exhibit excellent thermal insulation with a thermal conductivity of 0.39W/m·k, which is only 1/100 to 1/1000 of metal. The hollow structure of fiberglass profiles, sealed with rubber and wool strips, ensures significant thermal insulation. The heat transfer coefficient of fiberglass casement windows ranges from K0=2.2W/(m2·K) for double-glazed windows to K0=1.3W/(m2·K) for three-glazed windows with low-e glass, meeting the highest levels of the Chinese standard GB/T8484-2002.

Good Sealing Performance

Fiberglass doors and windows are assembled with glued and screwed corners, and all gaps are sealed with rubber and wool strips, resulting in excellent sealing performance. They have been tested to meet the highest levels of air tightness, watertightness, and overall performance according to Chinese standards GB/T7107-2002.

Healthy, Green, and Environmentally Friendly

The test results of fiberglass door and window profiles meet the requirements of GB6566-2001 for radioactive nuclides in building materials, making them safe and environmentally friendly with an internal radiation index of 0.2.

Good Sound Insulation

Fiberglass doors and windows provide excellent sound insulation. Tests show that Buzhoushan Door brand fiberglass windows have sound insulation levels of 36dB and 39dB, meeting level 4 of the national standards.

Corrosion Resistance

Fiberglass is highly resistant to corrosion from acids, alkalis, salts, and most organic substances. This makes fiberglass doors ideal for use in rainy, humid, coastal areas, and places with corrosive environments.

Good Dimensional Stability

With a linear expansion coefficient of 7.3×10-6/℃, fiberglass profiles are more stable than steel, aluminum alloy, and plastic. Temperature changes do not affect the normal operation of fiberglass doors and windows.

Good Weather Resistance

Fiberglass is a thermosetting plastic that remains stable even at high temperatures above 200℃ and performs exceptionally well in low temperatures. It does not melt and retains its structural integrity under extreme conditions.

Good Insulation Performance

Fiberglass is an excellent insulating material unaffected by electromagnetic waves and can withstand high voltage without damage, making it suitable for special uses in outdoor buildings and communication system structures.

Good Shock Absorption

Fiberglass profiles have a high shock absorption frequency due to the combination of resin and fiber, providing shock absorption and anti-seismic capabilities that prevent early damage from resonance.

Rich Colors

Fiberglass profiles can be coated with various finishes, allowing for a wide range of color options to match different architectural styles and preferences.

Conclusion

New fiberglass doors offer a host of benefits, including lightweight strength, energy efficiency, excellent sealing, sound insulation, and resistance to corrosion and weather. These features make fiberglass doors an ideal choice for enhancing both the functionality and aesthetic appeal of your home.
