Tunnel Greenhouses - Buy direct from NZ manufacturer

Our most popular home garden tunnel houses and one of NZs largest selling brands use sturdy 32mm square aluminium for the tunnel hoops formed in one single piece for strength.
Super long-life Duratough 215 micron thickness commercial grade greenhouse film is used for the covering which has a 10 year + service life. Duratough locks in night-time temperatures whilst transmitting superior light levels to your plants during the day. Duratough is durable against storm, sun, snow and hail plus it is safe around the home and unlike polycarbonate or glass it can resist impact from items such as soccer balls, basketballs, cricket balls etc.
The frame is all durable aluminium including the 60mm x 30mm aluminium base rail so that there is no timber to rot or steel to rust at ground contact. A sliding door and 3 blade glass louvre window is included with all models. All tunnel houses 6m or longer have a large 1.6m length roof vent which you can choose to have a solar powered ram to open and close it automatically.
To save you time we deliver the greenhouses 50% assembled with the end walls, louvre window and door frame made up.
Redpath is a trusted NZ greenhouse brand - We have supplied 1000's of greenhouses nationwide to happy customers. You can purchase your tunnel house direct from our factory, we warranty what we sell and deliver direct to your door.
