PVC Infill

Designed to be used with our single and double aluminium extrusion profiles, this PVC infill provides a secure, weather-resistant seal for your polytunnel. The ‘U’ and ‘T’ profile shapes are gentler on polythene or netting compared to metal fasteners, helping to reduce wear and prolong the life of your coverings. Each infill is supplied in a 1.5m length and fits neatly into the extrusion to offer a cleaner, more professional finish. Not only does it improve the visual appearance of your tunnel, but it also plays a key role in cutting out draughts and keeping the internal environment more stable. The design allows for easy removal and reusability, making seasonal adjustments or maintenance simple. Whether you’re building a new tunnel or upgrading your current setup, this infill is a practical choice for long-lasting performance and protection against the elements.
