Choosing the right Polycarbonate Sheets can make a significant difference to the durability, performance and long-term value of your project.
Whether you're installing a greenhouse, replacing roofing panels, building a canopy or sourcing materials for commercial glazing, selecting the correct sheet thickness, structure and finish is essential.
This guide explains everything you need to know before buying polycarbonate sheets, including the differences between solid and multiwall sheets, recommended thicknesses, common applications and how to choose the best option for Irish weather conditions.
Why Choose Polycarbonate Sheets?
Polycarbonate has become one of the most popular glazing materials across Ireland thanks to its outstanding strength, lightweight design and excellent weather resistance.
Compared with traditional glass, polycarbonate offers:
- Up to 200 times greater impact resistance
- Excellent UV protection
- Lightweight for easier installation
- High thermal insulation (multiwall sheets)
- Long outdoor lifespan
- Low maintenance
- Outstanding light transmission
These qualities make polycarbonate ideal for both domestic and commercial projects.
Types of Polycarbonate Sheets
Understanding the differences between sheet types is the first step in choosing the right product.
Multiwall Polycarbonate
Multiwall Polycarbonate features internal air chambers that improve insulation while reducing weight.
Best suited for:
- Conservatories
- Greenhouses
- Carports
- Pergolas
- Covered walkways
- Patio roofing
Benefits include:
- Excellent thermal insulation
- Reduced heat loss
- Lightweight construction

Choosing the Right Polycarbonate Sheet Thickness
Different applications require different sheet thicknesses.
| Thickness | Recommended Use |
|---|---|
| 2–4mm | Protective glazing, signs, machine guards |
| 6mm | Small canopies, greenhouses |
| 10mm | Pergolas, patios, roofing |
| 16mm | Conservatories, larger roofing projects |
| 25mm+ | Commercial roofing and high-performance insulation |
When choosing thickness, consider:
- Wind exposure
- Roof span
- Snow loading
- Thermal performance
- Budget
Best Applications for Polycarbonate Sheets

Polycarbonate vs Glass
Many customers compare polycarbonate with traditional glass before making a purchase.
| Polycarbonate | Glass |
|---|---|
| Extremely impact resistant | Can shatter |
| Lightweight | Heavy |
| Easy to install | Difficult to transport |
| UV protected | Varies |
| Better insulation (multiwall) | Lower insulation |
| Safer | Breakable |
For most roofing and glazing applications, polycarbonate delivers better long-term performance and lower installation costs.
Polycarbonate vs Acrylic
Although both materials are transparent plastics, they serve different purposes.
Choose Polycarbonate when you need:
- Maximum impact resistance
- Roofing applications
- Safety glazing
- Outdoor durability
Choose Cast Acrylic when you need:
- Superior optical clarity
