We are planning on replacing our front entry door and storm door. We live 2 blocks from the water and were told wood is not a good choice. We currently have a steel door. Would steel or fiberglass be better? We were told fiberglass can warp because heat will get trapped between storm door and entry door. We looked at HMI doors. Does anyone have this brand or know about it? Any suggestions or recommendations for door type or brands? Thanks.
