Oratex Fabric Covering Revisited

[Danzer1]

The goal of UV protectant (in this case) is to protect the covering material, not whatever's on the other side. On a window you are protecting the stuff on the inside of the window (furnishings, carpet, etc.). The Polyfiber method is simply used for a layman (home builder) to discern if you have enough coverage for their method (and is likely overkill). I'm suspecting the Oratex pre-impregnated material is more efficient (being factory applied) and (I believe) it has been tested to ensure it's adequate for it's intended purpose.

I was told by betteraircraftfabric.com that the Oratex 6000 is $76.85 per square yard and the Oratex 600 is $53.80 per square yard. It should be noted that that is square yard vice linear yard in case you want to compare with ceconite or Polly. I am just wondering if a Kitfox SS7 can be covered with 600 vice 6000. According to their website any LSA can be covered with 600.

Hi bushfly,
The Oratex 600 is approved for aircraft with a MTOW of 1323# (600 Kg). The 6000 goes clear up to 13,228# (6000 Kg). The 600 can probably be compared to the light PolyFiber fabric. I think that a SS7 covered with 600 would be marginal. The airframe is designed for 1550# gross, & you would be limiting yourself if you ever wanted to increase your weight to that limit (taking it out of the LSA category). That would be my concern. The 6000 is tougher, while still being considerably lighter than a conventionally finished/painted covering.
