It cost me £147 to clad a 6ft wall with a 4ftsq window. Some of the cost was window trim which is ver poor quality and I eould say, not fit for purpose. I say this as I've previously used widow trim for tiles which is such a robust product. I accidentally caught the trim whist fitting the sill and it just buckled, it has no strength. If you're asking me if I'd buy it again, it would be no. Although I hope my wall is now more insulated and that was my goal. Also, the front finish is paper thin znd will damage easily. I am sorry to leave this less than positive response but ig was my experience.
