Why polycarbonate

Better than glass for Irish conditions

  • 250× stronger than glass
    Withstands hail, heavy rain, and strong winds without cracking or shattering. Ideal for Ireland's unpredictable Atlantic weather.
  • 80%+ light transmission
    Lets in plenty of natural light while diffusing it evenly — no harsh hotspots that would scorch plants or overheat a space.
  • Thermal insulation
    Twin wall and triple wall sheets trap air between layers — reducing heat loss in winter and keeping covered areas comfortable year-round.
  • UV-stabilised — won't yellow
    All our sheets include a co-extruded UV-protection layer. No yellowing or brittleness, even after years of outdoor exposure.

FAQ

Common questions about polycarbonate roofing

10mm twin wall is the most popular choice for pergolas across Ireland. It provides a good balance of light, thermal insulation, and structural strength — and handles wind and rain well. For smaller or more sheltered structures, 6mm is a cost-effective alternative.
Quality UV-stabilised polycarbonate typically lasts 15–25 years. All sheets we stock include a co-extruded UV-protection layer on the outer face, which prevents the yellowing and surface breakdown that cheaper, uncoated sheets suffer from.
Polycarbonate is easy to cut on-site with a fine-toothed saw or Stanley knife (for thinner sheets). We sell sheets in standard sizes — call us on 085 8400 403 if you need guidance on how to cut cleanly without cracking the sheet.
For a standard installation you'll need: aluminium H-joiners (to connect sheets), F-profile endstops (to cap the open ends), breathable sealing tape (to seal the flute ends and prevent insects/condensation), and capped screws. We stock all of these — you can add them to your order alongside the sheets.

We also stock all the fixings and accessories required for a complete installation: aluminium H-joiners, F-profile endstops, breathable sealing tape, and capped screws.

Why choose polycarbonate over glass for roofing in Ireland?

Polycarbonate is 250 times more impact resistant than glass, weighs significantly less, and provides better thermal insulation through its multi-wall structure. For Irish conditions — with Atlantic wind, heavy rainfall, and occasional hail — polycarbonate outperforms glass on durability while remaining far easier to handle and install. UV-stabilised polycarbonate sheets maintain their clarity for 15–25 years without yellowing or becoming brittle.

Polycarbonate roofing sheets — buying guide

The most important decision when buying polycarbonate roofing sheets is thickness. 6mm twin wall suits smaller structures and sheltered positions. 10mm twin wall is Ireland's most popular roofing sheet, used for pergolas, carports, and garden canopies. 16mm triple wall provides the highest insulation and is recommended for conservatories or any structure used year-round. Call us on 085 8400 403 and we'll advise on the right option for your specific project and location.
