Installation Guide: Polycarbonate Multiwall Sheets

This guide provides general instructions for installing polycarbonate multiwall sheets. For detailed information and product-specific recommendations, please refer to our comprehensive installation catalogue.

Safety First:

Ensure optimal protection by wearing gloves, safety glasses, and long sleeves when handling polycarbonate sheets.

Proper Storage

Store sheets flat on a stable surface, protected from direct sunlight and weather to prevent warping or damage.

Acclimatisation

If the sheets have been in cold storage, allow them to adjust to room temperature before installation to minimise warping.

Gather Tools:

Assemble the necessary tools, including a utility knife, saw (circular or jigsaw recommended for cleaner cuts), drill, and screwdriver.

General Installation Steps

1. Preparation

Measure and Cut: Carefully measure the installation area and cut the polycarbonate sheet to size, leaving a small gap for thermal expansion (consult the catalogue for specific recommendations on gap size).
Identify UV Protection: Locate the UV-protected side of the sheet (usually marked with a film). This side should face upwards during installation for maximum UV protection

2. Support Structure

Strength and Level: Ensure your support structure (framing, rafters, etc.) is level, plumb, and can handle the weight of the polycarbonate sheets. Refer to the catalogue for recommended spacing between support beams to ensure proper load distribution.

3. Cutting and Drilling

Sharp Cuts: Use a sharp blade or saw to cut the polycarbonate sheet, ensuring clean and precise cuts. Avoid scoring or scratching the surface to maintain its integrity.
Proper Drilling: Drill holes at least 2-3 times the diameter of the fastener away from the sheet's edge to prevent cracking. Use drill bits specifically designed for plastics for optimal results.

4. Fastening

Appropriate Fasteners: Use appropriate fasteners with washers designed for polycarbonate sheets to ensure a secure and weatherproof connection. Do not over-tighten, as this can cause the sheet to crack.
Thermal Expansion: Allow for thermal expansion by using slightly oversized holes and slotted fastening points (consult the catalogue for details on recommended hole size and slot design).

5. Sealing (Optional)

Enhanced Weatherproofing: For certain applications, a silicone sealant compatible with polycarbonate may be used to improve weatherproofing. Refer to the catalogue for specific sealant recommendations to ensure compatibility.

6. Protective Film Removal

Final Touches: Once installation is complete, carefully peel off the protective film from both sides of the sheet to reveal the brilliant clarity or rich color of the polycarbonate.

Cleaning and Maintenance: Polycarbonate Multiwall Sheets

To ensure the longevity and optimal performance of your polycarbonate multiwall sheets, follow these cleaning and maintenance guidelines:

1. Regular Cleaning

☑ Use Mild Detergent: Clean the sheets with a mild detergent mixed with lukewarm water. Avoid harsh chemicals or solvents that can damage the surface.
☑ Soft Cloth or Sponge: Use a soft cloth or sponge to gently wipe the surface. Avoid abrasive materials that could scratch the polycarbonate.
☑ Rinse Thoroughly: After cleaning, rinse the sheets with clean water to remove any soap residue, and then dry with a clean, soft cloth to prevent water spots.

2. Stain Removal

☑ Identify Stains: For stubborn stains, use a solution of mild detergent and water. Apply the solution with a soft cloth and gently scrub the area.
☑ Avoid Abrasives: Do not use abrasive cleaners or scrubbing pads, as these can scratch and damage the surface.

3. Inspection

☑ Regular Checks: Periodically inspect the sheets for any signs of damage, such as cracks, scratches, or loose fittings. Address any issues promptly to prevent further damage.
☑ Check Seals: Ensure that any sealing or gaskets are intact and functioning properly to prevent water ingress.

4. Avoid Harsh Conditions

☑ Prevent Accumulation: Regularly remove debris, such as leaves or dirt, to prevent buildup that can obstruct light transmission or cause staining.
☑ Protect from Chemicals: Keep the sheets away from strong chemicals or solvents that could damage the surface or reduce its effectiveness.

5. Professional Maintenance

☑ Consult Experts: For any major repairs or maintenance issues, consult with a professional to ensure that repairs are done correctly and do not void any warranties.
