Add a 2 m section to your greenhouse
An extension, not a standalone greenhouse The Agromax extension adds a 2 m-long section to an existing 4 m-wide greenhouse, increasing the growing area by 8 m². It is designed to fit between existing sections of the greenhouse frame, rather than at either end. Check that the extension is suitable for your existing greenhouse before choosing it.
Extension details
- Adds length in the middle: The 2 m section fits between existing frame sections. The greenhouse end walls remain in place; follow the manufacturer’s instructions when assembling the extension.
- Adds 8 m² of growing area: The extension is 2 m long and has a stated height of 2.96 m. It is intended for an existing greenhouse that is 4 m wide.
- Galvanised steel frame: The frame is galvanised steel, with 40 × 20 mm and 20 × 20 mm sections.
- 4 mm polycarbonate covering: This version is specified with clear 4 mm polycarbonate. Choose a covering thickness that matches the existing greenhouse when planning an extension.
