Advantages Strong with high levels of nail tear and puncture resistance. Rot proof and long lasting. Lightweight – easy to transport and handle rolls. Flexible and easy to cut. Quicker to install than traditional bituminous 1F underlays. Easily chalk marked.

Designed for rafter roofs in exposed sites, where greater mechanical performance is essential, MonarTile Supa-R reinforced lining offers exceptional strength and durability while remaining lightweight, flexible, and therefore easy to install.

Ideal for a wide range of applications, from small domestic installations to major commercial projects, the lining is both water and rot proof, and ideal for low-pitched roofs. In addition, by absorbing condensate directly into the underlay it reducesthe 'drip effect' thereby, the lining further protects insulation materials.
