Tunnelhouse NZ Made “Built stronger – To last longer”

Redpath aluminium tunnelhouse’s are one of NZ’s most popular and we have supplied many 1000’s to happy home gardeners, lifestylers, schools & institutions nationwide. Compare the size of our sturdy 32mm square aluminium hoops and 25mm square purlin rails which give excellent strength and durability.
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. 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.
The tunnels use Duratough 215 micron commercial grade greenhouse film which is the thickest grade in the industry with a 10 year + service life.  Duratough is specifically designed for plant production and has exceptional P.A.R light transmission to help lock in night-time temperatures and give superior light levels during the day. Duratough is extremely durable against storm, sun, snow and hail plus it is safe around the home.
You can personalise your tunnel with many optional extras to ensure your greenhouse 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 if required or add an optional solar powered automatic opener to any or all roof vents.
All models include a 650mm wide sliding roller bearing aluminium front door.  A rear wall door may also be fitted as an option.  A wider 850mm ‘Wheelchair / Wheelbarrow” access door is an option at either end, as is a ‘dual door” option with one door clad in breathable mesh and the other in Duratough.
All tunnels include a rear wall louvre window as standard,  Plus you can select additional sidewall louvre vent(s) as an option.
Other options include aluminium shelves for the sidewall(s) or across the rear wall, and for extra cooling in the summertime you can select a temporary “throw-over’ shadecloth cover or fit a full length fixed sidewall 350mm deep shadecloth sidewall vent. You can also add the ” X” wind kit for exposed sites which adds extra wall bracing and arch braces.
