Fibreglass (or GRP) is a plastic material composed of glass fibres reinforced with a thermosetting resin.
Despite its resinous and filamentary appearance, it has a transparency coefficient similar to that of polycarbonate, i.e., 0.86. However, it is subjected to quick yellowing and is less elastic than polycarbonate due to the resin that composes it.
Like polycarbonate, fibreglass used for roofing is also produced in sheets with a flat or corrugated profile and can be flat or curved, transparent or opaque. It is available in different widths and lengths and sold in rolls, ready for installation.
The aesthetic appearance of GRP is not especially elegant-looking, and this feature makes the material scarcely requested by private DIY enthusiasts, architects and interior designers.
Benefits of fibreglass
- Resistance to chemical agents
- Resistance to atmospheric agents
- Good quality/price ratio
Disadvantages of fiberglass compared to polycarbonate
- Quick yellowing
- Scarce elasticity
- Low thermal insulating capacity
- Few customization possibilities
- Not especially elegant-looking
The benefits of polycarbonate compared to glass, plexiglass and fiberglass
Compared to what we have so far explored about the technical features of glass, plexiglass and fiberglass, polycarbonate ensures a wide range of benefits that make it the preferred choice for a variety of applications:
- Thermal and mechanical resistance
- Hardness and Resistance
- Resistance to load and wind pressure
- Improved fire resistance
- Thermal insulation
- Recyclable and easy to clean
- Variable thickness
