Redpath import the specialist long life Durashelter super heavy duty 230micron thickness and Duratough heavy duty 180micron thickness “EVA” (Ethyl Vinyl Acetate) roofing membrane from Belgium. Both Durashelter and Duratough are extruded in Europe to a very exacting tolerance. The polymer resin used in this specialist roofing membrane includes a high percentage of elasticized EVA which gives the roofing superior flexibility and longevity. The latest technology “HALS” (Hindered Amine Light Stabilizers) are used in these two coverings to provide the longest possible life and UV stability properties.
Durashelter is up to 30% thicker than the roofing membranes used by our competitors and offers farmers superior resistance to weather and longer service life. This becomes particularly important when the standoffshelter is constructed on an open farm site with high exposure to wind.
Redpath has been using Duratough in New Zealand and Australia for almost 20 years and the very latest Durashelter product has been introduced since 2007. Life expectancy of the product is excellent. Duratough is supplied with a 4 Year pro-rata UV warranty and the actual realistic service life of Duratough can be 6 – 8 years. Durashelter is supplied with a 5 Year pro-rata UV warranty and the actual realistic service life of Duratough can be 7 – 10 years.
Durashelter and Duratough both offer a high “PAR” light transmittance level (photo-synthetic light activation), - this plays a large part in the drying effect of the floor inside the standoffshelter and also helps keep the microbiological organisms within the deep litter system (woodchips, post peelings, sawdust or bark etc) to remain active and healthy whilst naturally breaking down manure/ effluent. The drying effect provided by the natural sunlight entering through the roof keeps your cows warm, dry and happy.
Redpath hold large stocks of the roofing membrane Durashelter and Duratough in stock in New Zealand and operate seven building crews for its efficient installation and for long term maintenance needs.
Both Durashelter 230 micron and Duratough is securely fastened to the standoffshelter building via Redpaths patented Lockstrip or Duralock aluminum clipping system. These fastening or "clipping" systems secure the roofing membrane without puncturing it & therefore extend the service life of the roof.
