General
Polycarbonate is extremely strong and nearly unbreakable, making it suitable for applications like police shields, awnings, sunroom roofing, and greenhouses. These panels are resistant to various weather conditions and maintain their appearance for many years.
Polycarbonate sheets can be easily cut using a circular saw or a jigsaw. Circular saws are best for cutting larger lengths, while jigsaws require careful handling to ensure proper cuts.
Although polycarbonate sheets may change colour over time due to sun exposure, Excelite's UV-coated polycarbonate sheets maintain their colour longer.
Polycarbonate sheets require minimal maintenance. Gentle cleaning with warm soapy water and a soft cloth is typically sufficient. Avoid abrasive cleaners, brushes, or pressure washing, as these may damage the UV-resistant coating or scratch the sheets
Roofing
The best sheeting for a roof depends on the specific requirements, with multi-wall, solid, and corrugated polycarbonate sheets each offering unique benefits.
Although polycarbonate sheets are tough and durable, they should not be walked on. They can withstand many impacts, but might dent or scratch under the weight of a person. Additionally, their surfaces are slippery due to the UV-resistant film, posing a risk of slipping and injury.
Corrugated and twin wall polycarbonate sheets are typically the least expensive varieties. Despite the lower price, these sheets can endure Australia's harsh weather conditions, but selecting the wrong type may lead to more expenses in the long term.
Pergolas & Greenhouses
Excelite's popular glass-look polycarbonate flat roofing is an excellent choice for a pergola roof. It is easy to install, low-maintenance, and watertight, making it a great alternative to glass.
or a pergola enclosure with a glass-like appearance, use a 4-6mm thick solid polycarbonate sheet. Alternatively, use twin-wall polycarbonate panels for a more affordable, yet less transparent option.
Twin wall polycarbonate is ideal for greenhouse construction due to its insulating properties and minimal framing requirements. Excelite Softlite polycarbonate sheets are another excellent option for greenhouse materials, especially for tunnel greenhouses.
