When it comes to greenhouse construction, selecting the right material is crucial for ensuring optimal plant growth and long-term durability. Polycarbonate has emerged as the top choice for both hobbyists and commercial growers due to its exceptional properties.

Benefits of Polycarbonate Over Glass

•              Superior Insulation: Twin-wall and multi-wall polycarbonate panels trap air between layers, providing excellent thermal insulation that helps maintain stable temperatures inside the greenhouse.

•              Impact Resistance: Unlike glass, polycarbonate is virtually unbreakable, making it an ideal choice for areas prone to extreme weather conditions.

•              Light Diffusion: Polycarbonate panels provide uniform light distribution, reducing hot spots and ensuring that plants receive even sunlight exposure.

•              UV Protection: Many polycarbonate sheets come with a UV-resistant coating, preventing yellowing and degradation over time.

Best Panel Types for Greenhouses

•              Twin-wall panels – Ideal for balancing light transmission and insulation.

With its combination of durability, energy efficiency, and ease of installation, polycarbonate is the best solution for modern greenhouse structures. We offer various panels with different light transmission levels, ranging from:

•              20% (white color)

•              25% (bronze)

•              50% (light bronze)

•              85% (clear)

This variety allows you to grow a wide range of fruits and vegetables under optimal conditions. Not only does this create a healthier and more sustainable food source, but polycarbonate panels also have an impressive lifespan of more than 10 years, making them a long-term investment for greenhouse growers.

When designing an outdoor living space, selecting the right roofing material is essential for comfort, durability, and aesthetics. Polycarbonate panels have become the preferred choice for patios, pergolas, and outdoor structures due to their exceptional ability to provide protection from both the sun and rain while maintaining a stylish and modern look.

Why Choose Polycarbonate for Your Patio or Pergola?

Polycarbonate panels offer several advantages over traditional materials like glass or metal, making them the ideal roofing solution for outdoor spaces.

1. Superior Sun Protection

•              Blocks Harmful UV Rays – Many polycarbonate sheets come with a UV-resistant coating that protects against harmful sun exposure, reducing the risk of sunburn and keeping the space comfortable.

•              Light Filtering Options – Available in various tints and opacities, polycarbonate panels allow you to control the amount of sunlight that enters, providing a pleasant shaded environment.

2. Excellent Rain Protection

•              Waterproof & Weather-Resistant – Unlike fabric or wooden pergola covers, polycarbonate panels are completely waterproof, ensuring your outdoor space stays dry even during heavy rainfall.

•              Impact Resistance – Designed to withstand hail, strong winds, and extreme weather conditions, polycarbonate is far more durable than glass or acrylic alternatives.

3. Long-Lasting Durability

•              Highly Resistant to Cracking & Fading – Unlike traditional materials, polycarbonate does not crack, yellow, or weaken over time, ensuring a long lifespan of 10+ years.

•              Low Maintenance – Polycarbonate panels require minimal upkeep, only needing occasional cleaning with mild soap and water to maintain their clarity and performance.

4. Modern & Aesthetic Appeal

•              Stylish & Sleek Design – Whether you prefer a clear, tinted, or frosted look, polycarbonate offers a modern and elegant touch to your outdoor structure.

•              Lightweight & Easy to Install – Compared to heavy glass, polycarbonate is significantly lighter, making installation quicker and more cost-effective.

FAQ About Polycarbonate Installation: Expert Views on Slope and Waterproofing

Below is a list of FAQs that may help you:

1. How to Create a Slope?
Experts recommend creating at least a 5-degree slope. Here’s an easy calculation to achieve the required 5-degree slope: If you have a roof length of 12 feet, the upper roof end should be 1 foot taller than the lower end.

Option 1: You can cut the whole beam diagonally to create two shims for the slope.

Option 2: Install or reinstall the ledger board and attach it to the roof or the wall.

2. Is Flashing Necessary at the Edges of the Polycarbonate Roof?
You can use aluminum or galvanized metal flashings at the edges to ensure that rainwater doesn’t seep into the gaps between the polycarbonate panels and the beams.
Alternatively, you can use an overhang instead of flashing.

3. Overhang.

An overhang extends the polycarbonate panels beyond the edge of the beam.
Recommend overhang is 6 inches. The maximum overhang is 12 inches.

4. Gutters

Installing gutters along the edge of your polycarbonate sheets is a great way to manage water runoff. Gutters collect rainwater from the roof, directing it away from your patio or structure to prevent leaks and damage.

To install gutters:

Attach the gutter securely along the bottom edge of the polycarbonate sheets.

Ensure proper alignment so that the water flows seamlessly into the gutter system.

5. How to Extend the Length of Polycarbonate Sheets: Overlapping or H Profiles

When the length of your polycarbonate sheets isn’t sufficient to cover the entire area, there are two primary methods to achieve the desired length: overlapping the sheets or using an H profile to connect two panels. However, neither method is ideal, so it’s always better to use a single, continuous panel whenever possible.

Overlapping Polycarbonate Sheets

One way to extend the length of your installation is by overlapping the sheets. This method creates a seamless joint where one sheet overlaps the next, ensuring water flows off the roof without seeping between the sheets.

How to Overlap Sheets Properly:

•              Overlap the polycarbonate sheets by at least 12 inches to prevent water penetration at the joint.

•              Ensure the overlap is aligned with the slope of the roof so water runs down and off instead of getting trapped.

•              Maintain a minimum roof slope of 5 degrees when using this method to ensure effective water drainage.

•              Adjust the height of the rafters. For example if you use 14 mm panels the height of 1 rafters should be 14 mm higher than another.

Using an H Profile to Connect Panels:

Align the Sheets: Position the edges of the two polycarbonate sheets you want to join, ensuring they are straight and properly aligned.

Insert the H Profile: Slide the H profile into place between the sheets, ensuring a snug and tight fit along the joint.

Secure the Panels: Use screws with rubber washers to fix the panels and the H profile to the supporting structure. This prevents leaks and ensures stability.

Seal with Silicone: Apply a bead of silicone along both sides of the H profile where it meets the sheets. This provides an additional layer of waterproofing and helps prevent dust or debris from entering the joint.

6. How Do I Connect the Polycarbonate Roof to My House Wall?

When attaching a polycarbonate roof to the wall of a house or building, you should use L flashing to create a waterproof seal between the roof and the wall. This prevents water from getting behind the sheets and into the house.

To connect to a house wall:

Place the L flashing between the top edge of the polycarbonate sheets and the wall.

Secure the L flashing tightly to both the wall and the sheets, ensuring there are no gaps.

 7. List of Materials for Twin-Wall Polycarbonate Panel Installation:

- Polycarbonate Sheets: The main and key component.

- Connectors (H or Snap Profiles): Used to connect two sheets together.

- U Caps: Used to cover the ends of the sheets.

- Vented Tape: Protects against moisture and dust particles.

- Screws with Plastic Washers or Screws with Neoprene Washers: Ideal for preventing rainwater leaks.

Tools:

- Measuring Tape: Essential for adjusting the polycarbonate sheets.

- Drill: Useful for creating precise screw holes.

- Circular Saw or Jigsaw: Used to cut and adjust panels.

- Safety Glasses: Protect against potential eye damage during installation.

8. How to Calculate the Number of Screws
For proper installation, it’s recommended to place screws every 2 feet in each direction. At the same time, you should place screws where you have an H or snap connector.
Here’s a reference for a standard 4 ft x 8 ft sheet size:

- For one sheet (4 ft x 8 ft), you will need approximately 15 screws.

- For two sheets connected with an H or snap profile (4 ft x 8 ft), you will need around 25 screws.

- For three sheets connected with an H or snap profile (4 ft x 8 ft), you will need about 45 screws.
