One of our clients is planning to use a tackable fabric tile composed of NAUF MDF, fiberboard (fiberglass with a urea formaldehdye resin), UF-free adhesive and fabric. The tile is like a sandwich. The fiberglass layer is clearly not wood nor agrifiber. But it does contain urea formaldehyde. In a case where this layer is glued to the MDF, what is your sense of its ability to meet IEQc4.4? Thanks!
