Sigma Lux

The Greenhouse Sigma Lux is a premium, high-performance greenhouse built for Irish weather. Its reinforced steel frame with alu-zinc coating ensures exceptional strength and durability, while aluminium end walls, vents, and new improved doors with integrated locks provide a modern, secure, and refined finish. Designed for longevity and easy assembly, the Sigma Lux offers the same proven strength as the classic Sigma — with upgraded materials, superior protection, and a truly premium look and feel.
