NOT RECOMMENDED FOR
While polycarbonate H joiners work well for many applications, we do not recommend them for pergola roofs or other permanent, high-visibility architectural installations. For these applications, we strongly recommend our Aluminium H Glazing Bars, which offer:
- Heavy-duty construction for long-term durability
- Longer lifespan (20+ years)
- Superior weather resistance
- Professional appearance
- Easier installation with integrated sealing
INSTALLATION GUIDE
- Measure & Cut: Measure the length required and cut the H joiner to size using a fine-tooth saw.
- Position the Joiner: Place the H joiner where two polycarbonate sheets will meet.
- Insert First Sheet: Gently slide the first twin wall polycarbonate sheet into one side of the H connector slot.
- Insert Second Sheet: Slide the second sheet into the opposite side of the H connector.
- Secure with Screws: Fix the H joiner to the supporting structure by screwing through the centre of the profile at regular intervals (typically every 300-400mm).
- Seal if Required: For additional weather protection, apply silicone sealant along the edges where sheets meet the joiner.

Polycarbonate H Joiners:
- ✓ More affordable upfront cost
- ✓ Lightweight and flexible
- ✓ Easy to cut and modify
- ✗ Shorter lifespan (approx. 10 years)

Aluminium H Joiners (Recommended for 99% of applications):
- ✓ Heavy-duty and long-lasting (20+ years)
- ✓ Superior weather resistance

Polycarbonate sheeting 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.
Please be aware that a suitable blade is required for cutting. We recommend using a 60 teeth fine blade for optimal results.

Selecting the right pergola roofing involves considering factors such as your budget, preferred design, frame style, and color preferences. It's crucial to engage in discussions with a pergola roofing supplier before initiating the construction of your frame.
Polycarbonate Roofing
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 because it's smooth, posing a risk of slipping and injury.
Polycarbonate Corrugated sheet 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.
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 Corrugated and embossed polycarbonate sheets are another excellent flexible option for greenhouse materials, especially for curved roofing or tunnel greenhouses.
