610mm x 527mm x 15mm Greenhouse Window (3mm Polycarbonate)

Virtually Unbreakable, Insulated & Perfect for Year-Round Growing

For our most durable greenhouse glazing option, this 3mm thick polycarbonate panel offers unmatched strength and longevity. 200 times stronger than glass, it provides exceptional impact resistance, making it an ideal replacement for Halls greenhouse triangular windows. Designed to withstand harsh weather, storms, and accidental damage, this virtually unbreakable panel ensures long-term greenhouse protection.

Polycarbonate also provides 99% UV protection, preventing harmful rays from damaging your plants while allowing evenly diffused light to support healthy vegetable and flower growth. Unlike glass, which can lead to uneven heating, polycarbonate regulates greenhouse temperatures, ensuring a stable growing environment throughout the year.
