Should felt back carpet be glued to good underlay-or will it ruin it?

[Tingly]

hi there

I have got excellent quality underlay but am looking to change the carpet as have changed colour scheme

I have never had felt backed carpet before but the supplier and fitter said they glue it down

Will this ruin my underlay? And would i be better off with the normal hessian backed type?

Thanks

Check with the fitter I suspect he means the edges instead of using spiked gripper rod which might not be suitable.

Felt backed is cheap end of carpet sales, it tears very easy, hence glue.
