Undertile Linings – Product Range

A range of top quality, cost effective membranes for use in pitched roofs with suitably ventilated roof spaces.

Versatile, strong and durable, the MonarTile range on non-permeable pitch roof underlays deliver exceptional performance in applications of every size and in every location, whether domestic or commercial.

MonarTile undertile linings reduce wind load on tiles or slates, while providing secondary protection against wind-driven rain, snow and dust. Competitively priced, and readily available across the UK, the linings are designed to make on site handling significantly easier, and a range of tailored accessories also ensures a successful installation.


Monatile Supa-R

Monatile Supa-R is a high performance undertile lining ideal for small and large projects in weather exposed sites. It comprises a multi-layer synthetic membrane with a strong reinforcing grid giving the product a high level of tear and puncture resistance while remaining lightweight and easy to install.
