A successful greenhouse needs enough light, stable temperatures and a covering that survives the weather for years. This is where multiwall polycarbonate outperforms plastic film.
Diffused light instead of harsh light
The internal channels spread sunlight evenly over the plants, reducing scorched spots and letting light reach lower leaves.
Insulation that saves on heating and cooling
Air trapped inside the sheet reduces heat loss on winter nights and limits excess heat gain during the day.
Much longer life than film
Plastic film has to be replaced every few seasons, while UV-protected polycarbonate lasts for many years — lowering long-term cost.
Resists wind and hail
The rigid sheet will not tear, so strong winds and hailstones do not damage it the way they damage film.
What to choose
- Small greenhouses: clear multiwall, 4–6 mm.
- Large commercial greenhouses: 6–10 mm multiwall with UV protection.
- Very strong sun: clear-frosted or opal for extra diffusion.
