Ultraspan 10.65m span overview

The Redpath Ultraspan greenhouse is used mainly for year-round production of vegetables, flowers and nursery crops that require accurate environmental control irrespective of the outside conditions.

The Ultraspan may be twinskin or singleskin clad with Duratough or Durashelter long life greenhouse film with a service life of ten years +.  The cosecant rafter "A" frame design is a unique Redpath feature and it allows superior light transmission through to the crop via its reduced overhead structural shading.

The truss/rafter is also 'curved' so that any internal condensation is prompted to run to the edge of the roof sheets where it is trapped by an aluminium internal condensation trap. By reducing condensation light is further increased and damage from overhead dripping is eliminated.

The ridge ventilation system can be either single facing or double ridge type and incorporates a 'raised ridge apex connector' - allowing growers to partially ventilate the greenhouse even in poor or wet/humid weather conditions yet still allow moisture and rain to run off the ventilator opening, the roof ventilator also includes aluminium draft strip upstands along the full length of roof vent closure points which provide a weather flashing. 

The roof ventilation is typically fully automated with high quality 'Dutch' Ridder vent drives - although manual control is an option. Gutters are a 250mm wide structural part, and of 'walkthrough' design, the gutters allow substantial rainfall catching and easy access to the roof for maintenance and equipment. All gutters include a 100% rust-proof rain head at gutter ends to catch and duct rainwater to downpipes. Gutters are included standard on outside pole lines also.
