I am actually using the Novalis Vinyl flooring from Floorrich. I can say Im pretty satisfied with the quality and workmanship from them. Price wise compared to Evorich's HERF is different. Evorich quoted me higher actually. HERF which stands for High End Resilient Flooring is actually a term created by Evorich to marker their products. All Vinyl flooring is still Vinyl. As for the Floorrich's Vinyl flooring, they even showed me their test reports, including PSB's test report in Singapore. Their Vinyl flooring is certified Low-toxicity and comes with the Singapore Green Label. To be honest, you guys can try asking for test reports from Evorich and Floorrich and see it for yourself who can produce the necessary certificates. I have seen it for myself and that's why I chose Floorrich.
