Polycarbonate Sheets: Everything You Need to Know

Polycarbonate Sheets

Polycarbonate sheets are constantly gaining ground in the world of construction, architecture and everyday life. Flexible, durable, transparent and lightweight, they are an ideal solution for canopies, greenhouses, advertising signs, protective surfaces, as well as DIY applications. In this article we will answer all the basic questions about polycarbonate and its use.

What are polycarbonate sheets?

Polycarbonates are thermoplastic polymers characterized by excellent mechanical strength, thermal stability, and transparency. They are derived from a chemical compound that includes carbonates, and their production began in the 1950s.

They are widely used in:

  • Structural constructions (roofs, awnings, sheds)
  • Industrial buildings
  • Greenhouses
  • Production units
  • Security (e.g. armored glass, police shields)
  • DIY and hobbies (e.g. home or garden construction)

What are the main advantages of polycarbonate?

The main advantages of polycarbonate are:

1. Endurance

Polycarbonates are up to 200 times stronger than glass, making them ideal for applications where there is a risk of breakage.

2. Transparency

They maintain a high degree of transparency (up to 90%), which makes them suitable for natural lighting without losing safety.

3. Weather resistance

They have UV protection (when coated) and can withstand rain, sun, hail and snow.

4. Low weight

They weigh much less than glass or metal, reducing transportation and installation costs.

Are there different types of polycarbonate sheets?

Yes. The most common types are:

Solid Polycarbonate

  • Single, transparent sheets
  • Very high strength
  • Use in shields, safety partitions, canopies

Multiwall Polycarbonate

  • They have air “cells” inside
  • They provide better thermal insulation
  • Ideal for greenhouses, sheds, patios

Corrugated Polycarbonate

  • They resemble the well-known corrugated sheets (PVC boards)
  • They are mainly used for roofs and sheds.

Are they suitable for home use?

Absolutely! Polycarbonates are an excellent choice for:

  • Shelters on terraces or balconies
  • Parking lot coverage
  • Construction of greenhouses in the garden
  • DIY structures for shade or protection from the rain
  • Protective covers for balconies or playgrounds

How long does polycarbonate last?

The lifespan depends on the quality and whether they have UV protection. Good polycarbonate can last 15–20 years or more. It is important to choose certified materials and to install and maintain them correctly.

What is their difference from Plexiglass (acrylic);

FeaturePolycarbonatePlexiglass (Acrylic)
Impact resistanceVery high (almost unbreakable)Moderate – may crack
TransparencyVery goodExcellent

Heat resistanceHighLower
CostSlightly higherMore economical

How much does polycarbonate cost?

Prices depend on:

  • The type (solid or cellular)
  • The thickness (usually 4mm to 16mm)
  • The dimensions
  • Whether they have UV protection

Is polycarbonate environmentally friendly?

Polycarbonates are not biodegradable, however:

  • They are recyclable
  • They have a long lifespan, reducing the need for replacement
  • Reduce the need for artificial lighting (in applications such as greenhouses)

Although not a “green” material in the strict sense, they are considered a more sustainable solution compared to materials such as glass or PVC, especially when used properly.

What should I pay attention to before buying?

  1. UV protection – Make sure the sheet has a UV coating.
  2. Sheet thickness – The greater the thickness, the better the thermal insulation and mechanical strength.
  3. Quality certification – See if the product meets international or European standards.
  4. Fire resistance – Good polycarbonates are self-extinguishing.
  5. Warranty – Many reliable sheets come with a 10+ year warranty.

Can I install them myself?

Yes, polycarbonate is easy to install, as long as you have:

  • Tape measure & pen for measuring/marking
  • Jigsaw or cutting wheel
  • Drill/screwdriver for fastening
  • Special aluminum or plastic profiles for support and sealing
  • Sealing strips or silicone

Important: Always install with the UV protection facing outwards and leave room for expansion.

Frequently Asked Questions

How can I cut a polycarbonate sheet correctly?

You can cut polycarbonate sheet with:

  • Jigsaw
  • Fine-toothed cutting disc
  • Hand cutting tool for details

Before cutting:

  • Support the sheet well.
  • Mark the cutting point precisely
  • Place protective tape on the points to avoid “fraying”

How do I install polycarbonate sheets?

Installation is done in 4 basic steps:

  1. Cutting to the correct dimensions
  2. Use of suitable profiles (H, U, L) made of aluminum or PVC
  3. Fastening with screws with gaskets (rubber washers)
  4. Sealing with silicone or special sealing tape

Caution: Place the UV protected side outwards and leave room for expansion.

How do you clean polycarbonate without scratching it?

To properly clean a polycarbonate sheet:

  • Use water with mild soap.
  • Use a soft cloth or sponge.
  • Do not use alcohol or harsh cleaners.
  • Avoid wire or abrasive sponges.

A gentle cleaning every few months maintains transparency and extends lifespan.

Conclusion

Polycarbonate is a multifunctional, durable and lightweight material that can be used in dozens of applications. Whether you want to build a canopy, cover a greenhouse or protect an outdoor space, it is one of the most practical and smart choices.

Ensure excellent thermal insulation and protection by choosing the appropriate sealing materials according to the requirements of your space.
