SPANS 6m to 10.65m









Vented roof designs

The Redpath pitch roof ridge vented designs are the top of the line greenhouse designs from Redpath. Used for year-round production of vegetables, flowers and nursery crops that require accurate environmental control irrespective of the outside conditions.

These designs may be twinskin or singleskin clad with Duratough® 210 micron film. The cosecant rafter “A” frame truss design is a unique Redpath feature and it allows superior light transmission through to the crop via reduced overhead structural shading. The truss/rafter design is also shaped so that any internal condensation is prompted to run to the edge of the roof sheets. By reducing condensation sunlight transmission to the crop is further improved and damage from potential overhead dripping is reduced.

The ridge ventilation system can be either single facing or double ridge “gull wing”. The roof ventilator also includes aluminium draft strip upstands along the full length of roof vent closure points which provide a superior weather flashing and vents are fully automatic operating or available with a manual option.

Gutters are a heavy gauge folded type long-life 250mm wide structural part, and are a ‘walkthrough’ design. All gutters have a powder coated exterior and include a 100% rust-proof rain head at gutter ends. The gutters are included standard on outside pole lines also.

Redpath offers construction teams nationwide and we manage the building permit application and we then continue to offer local after sales service. Redpath have supplied and erected 1000s of these designs throughout our nearly 40 year history.
