The main frame and base rails are 100% aluminium with no timber to rot, rust or to taint soils from tanalising.
Our frames include an integrated groove to reliably fasten the covering and easily allow you to use different types of coverings if required. The latest Mk2 design has a simpler and speedier “V Lock” cover holding system. Taylor Built by Redpath’s tall 2.3m apex height gives plenty of height for crops and gives increased internal air volume to act as a temperature buffer and frost protector. Duratough is durable against storm, sun, snow and hail plus it is safe around the home.
Polyshade tunnels have quality commercial grade knitted 30% shadecloth in white colour fitted to the end walls and the door as standard. You can personalise your tunnel with many optional extras to ensure your Polyshadehouse matches your location and your crop growing needs
The 6m through to 12m length tunnels include a 1.6m length roof vent. The 15m and longer models include three roof vents, You can also add extra roof vents and also add an optional solar powered automatic roof vent opener to any or all roof vents.
All models include a 630mm wide sliding roller bearing aluminium front door. A rear wall door may also be fitted as an option. A wider 830mm ‘Wheelchair / Wheelbarrow” door is an option at either end.
Sidewall or rear wall shelves are an option, and for extra cooling you can select a temporary “throw-over’ shadecloth cover or fit a full length fixed sidewall 300mm deep shadecloth sidewall vent. You can also add a wind kit upgrade for modest cost if your site is a little more exposed, The wind kit adds extra Sidewall braces, Collar tie cross braces and reinforced hoop feet.
Custom sized raised gardens are made for the tunnelhouses – lengths are 1.4m, 2.8m and 4.4m. You can add as many gardens as you wish end-to-end to fit longer tunnels, and can also include an optional internal liner to act as a barrier between the stabilised timber and the soil.
