FRP for xterior and interior wall cladding

[rewatcher]

Praveen and other experts,

What is your opinion on using FRP based materials for exterior wall paneling and other facade related works ? Also what about using the same for interior wall cladding (wooden finish). I know companies like FunderMax and Veristo offers very good solutions for facade, but they come with a steep price tag. I see some companies offering FRP based products for a lesser price. What are the disadvantages of using FRP in terms of longevity, maintenance, looks etc.
Appreciate your feedback.
