Monarplan is a flexible PVC-P single ply membrane offering excellent characteristics of strength, elongation and weathering making it ideal for new build or refurbishment projects.

All membranes are reinforced and are available with or without a fleece backing providing scope for all methods of application and offering specifiers confidence in performance and unlimited freedom in design.

Mechanically Fastened System:

Monarplan FM systems rely on the use of fasteners and pressure plates installed at pre-determined centres within the overlap to attach the roofing system to the structure. The system offers fast application time, instant seam strength and reduced impact associated with inclement weather conditions. Monarplan FM membrane is mechanically attached through to the structural deck using Monarplan Tubular Fasteners of appropriate length. The fasteners are required to penetrate through the structural deck with a minimum projection to the underside of 25 mm.

Fully Adhered System:

Monarplan GF Fleecebacked membrane offers an ideal solution on very complex building shapes or where drilling and mechanical fasteners are inappropriate or impractical.

Warm Ballasted System:

Monarplan G membrane offers an ideal solution on very complex building shapes or where drilling and mechanical fasteners are inappropriate or impractical, and is fast to installation but can support the increased loading from the ballast material.
