Foshan Sunhouse Building Materials Co., Limited
SUNLON twin wall ppolycarbonate sheets is made of polycarbonate resin imported from Germany. It is the most popular material for construction and decoration. The transmission of sun panel is from 35-80% with double anti-UV protection. The hollow structure enhances the effect of heat insulation and sound insulation and makes it lighter to transport and install. Besides the characteristics of general hollow sheet, the crystal sun panel has better performance for the appearance and durability.
Production Application
Skylight in residence, workshop and warehouse, swimming-pool, gymnasium and greenhouse;
Shed for passageway, corridor and parking;
Sound-insulation walls of Expressway;
Screen decoration,advertisement light box, LED electronic screen.

Q:What are polycarbonate sheets?
A: Polycarbonate sheets are a transparent, synthetic product. Because of its exceptional impact, weather and temperature resistance, it provides solutions where other synthetics fail. Polycarbonate has a different chemical composition, and therefore different properties, from other transparent plastics such as PVC.
Q: Can I install polycarbonate sheets myself?
A: Polycarbonate sheets are particularly user-friendly and very light, so that fewer cross bars are needed. This makes the supporting structure more straightforward and cheaper.
Q: Do the sheets discolor overtime?
A: Because of its transparent UV protective layer polycarbonate sheets do not discolour and most polycarbonate sheets come with a 10-year guarantee... but they can last even longer than that!
Q: Won’t a polycarbonate roof make things very hot?
A: Polycarbonate roofing sheets come with an energy reflective coating, which helps solve this problem. Moreover, polycarbonate sheets have excellent insulating properties so that heating costs are considerably reduced during intermediate seasons.
Q: Do the sheets break very easily?
No! Polycarbonate sheets are not only extremely impact-resistant but thanks to their temperature and weather resistance they have a much longer service life.
Q: Is polycarbonate sheet bad for the environment?
Polycarbonate sheets are a very sustainable material that can be recycled and does not emit toxic substances during combustion. Moreover, there are sustainable polycarbonate sheets being manufactured using 20% renewable energy!
Q: What will happen in the event of a fire?
A: Fire safety is one of polycarbonate's strong points. Polycarbonate sheeting is flame retardant and do not emit toxic substances, which is why they are so often incorporated in public buildings, where the most stringent safety regulations apply.
Q: What is the impact strength of polycarbonate?
A: Polycarbonate is almost unbreakable. It is many times more impact resistant than any other transparent material used for glazing or roofing purposes. Many types of tests are used to measure impact strength, so it is difficult to compare data. Solid polycarbonate sheets comply with most tests issued on the impact strength of glazing materials. To give an idea: a 3 mm-solid polycarbonate sheet withstands the force of a steel ball of about 4 kg dropped from a height of 9.5 m, 3 times in a row. It does not break or shatter! When you take a look at some of the more industrial applications, you will see that polycarbonate is used for machine glazing, police riot shields, ice-hockey rinks... all applications that require extreme impact resistance.
