Description

This polytunnel greenhouse provides a protected growing space designed to support plant cultivation in outdoor settings such as gardens and allotments. By creating a sheltered environment, it helps reduce exposure to wind, cold and poor weather, allowing plants to grow more consistently across the season. It is well suited to growers who need a reliable structure for extending growing periods in less predictable climates.

Construction and Design

The frame is manufactured from galvanised steel and fitted with 6mm twin-wall polycarbonate panels. Two full-height doors are positioned at opposite ends, improving access and airflow compared with single-door greenhouses. Each door is edged with a steel surround to help reduce draughts, and both openings measure 805mm wide.

Installation of polytunnel greenhouse

This greenhouse can be installed directly into the ground without the need for a separate base. Each upright includes T-shaped ground anchors that are dug into the soil during installation. For those who prefer a fixed base, the structure can alternatively be secured to a foundation using angle brackets.

Polycarbonate Panels of a large greenhouse

The UV-treated twin-wall polycarbonate panels are lightweight, impact resistant and supplied with a 5-year warranty. The double-wall construction improves insulation while filtering UV light, offering a practical alternative to traditional glass glazing.

Strength and Stability

Additional rigidity is provided by stainless steel base rails, while every vertical support is anchored into the ground for improved stability in exposed conditions.

Ventilation

Each door includes an integrated top ventilation section. Opening the upper panel allows warm air to escape while maintaining protection at ground level. This supports airflow, helps reduce heat stress during warmer periods and encourages cross ventilation throughout the structure.

Tear-Drop Shape

The tear-drop profile increases usable headroom inside the greenhouse and adds extra strength against wind loading.
