ViroThatch: Bali perfectly imitates the traditional Balinese alang-alang thatch. Best of all, this is available with both a non-fire retarded as well as Class-A fire rating! Finally an alternative to PVC with a comparable fire rating, and none of the toxic or UV/fading PVC drawbacks. Brand new for 2011, Safari is proud to launch this new line of synthetic materials. HDPE (high-density polyethylene) material is 100% recyclable, non-toxic, safe, U/V stable and color-fast, it's maintenance and pest free, and is visually stunning!
