Quarantine units Overview

The level of quarantine required differs from facility to facility and therefore Redpath use the flexibility of our full buildings range to come up with a solution. Both natural and forced air fan ventilation systems are an option, as are internal partition walls, internal doors, double annex door entrances, specialty sealing of the frame and cladding from the outside environment.

Singleskin or Twinskin Duratough 215 micron Greenhouse film is used, or alternatively there is a white shaded roofing option using Durashade, Duraflex or White canvas.

Biomesh level 2 quarantine mesh is often used within our designs for any openings, exhausts, annex, anti-rooms etc.

Redpath operates 16 construction teams, we manage the building permit application and can help with resource consents if they arise. We then build on your site using local builders that then continue to offer local after sales service. Redpath have supplied and erected 1000s of these designs throughout our nearly 40 year history. A full set of registered engineers drawings and Producers statement for council building permit processing are included as standard
