1、 Comparison of Two Materials
When choosing a sunroof skylight sheet, we usually face two common material choices, namely FRP (glass fiber reinforced plastic) and PC (polycarbonate). Both materials have the characteristics of lightweight, high strength, and strong durability, but there are some differences in terms of performance and cost.
1. Strength and stiffness
Both FRP and PC materials have high strength and stiffness, but FRP has slightly higher strength and stiffness than PC. This means that FRP solar panels can withstand greater pressure and impact, and have better wind and earthquake resistance. However, for general civil buildings, the strength and stiffness of PC are already sufficient to meet the requirements.
2. Weight
FRP is lighter in weight than PC. If a large sunshade needs to be installed, the lightweight feature of FRP can reduce installation difficulty and cost. However, for small sunroofs, the strength and stiffness advantages of PC are more important.
3. Thermal insulation performance
FPR has better insulation performance than PC. If the sunroof needs to maintain a constant temperature or prevent condensation, FRP sheets are more suitable.
4. Price
Under the same thickness and specifications, the price of PC sunshade sheet is slightly higher than that of FRP. But FRP has higher strength, stiffness, and insulation performance, so from the perspective of cost-effectiveness, FRP is slightly better.
2、 Summary
In summary, when selecting the material for the skylight sheet of a sunroof, comprehensive consideration should be given based on actual needs. If higher strength, stiffness, and insulation performance are required, and the budget allows, FRP material sunlight shed sheets can be selected; If you need lighter weight and lower price, and do not have high requirements for strength and stiffness, you can choose PC material for the sunlight shed sheet.
