A 720 gauge specialist horticultural polythene sheeting use for covering polytunnel greenhouses. Manufactured with 'new' 5 layer co-extrusion technology using special chemical additives which help to reduce many fungal and bacterial diseases that can damage plants. This quality product also incorporates anti-fog characteristics that avoid condensation droplets falling on to plants and reduces heat loss, therefore maintaining a higher foliage temperature, leading to lower heating costs. During production, mineral additives are also used to diffuse light entering the tunnel, ensuring some light reaches the central, more shaded areas of the plants. This material carries a 5 year manufacturer's warranty against UV degradation.
To help protect polytunnel covers from degrading due to heat use our Anti Hot-Spot Tape.
To calculate the width required for replacement tunnel covers, measure over your hoop and add 2 metres for trenching into the soil. For length, measure the ridge bar and add enough each end to attach to the door frame or to trench in.
