Designing the Right Single Ply Roofing System

Fully Adhered Single Ply Roofing System – where the whole roof assembly is bonded using adhesives

Monarplan single ply roofing fully adhered systems are suitable for most applications particularly where improved aesthetic appearance or complex geometry are important design factors. 

In fully adhered systems the insulation is secured to bonded vcl with insulation adhesive. The roof membrane is then secured to the insulation using a special cold applied membrane adhesive.

Design and Installation Advice 

Monarplan GF Fleeceback membrane is secured to the insulation boards using a special cold applied adhesive. The adhesive is spread across the insulation boards and the Monarplan GF membrane is rolled into the adhesive. The adjacent sheets of membrane are positioned to allow an overlap which are then hot-air welded together with a hot-air welder to provide a continuous waterproof covering.

Perimeter Fastening

Regardless of the type of membrane attachment, mechanical fasteners are always required at the roofs perimeter, angle changes and any details. This ensures that any tensions generated in the field membrane are not transferred to other areas.

Insulation Attachment

Prior to the installation of the waterproofing, a fully bonded vapour control layer is applied to the prepared structural deck. Insulation adhesive is applied

to the upper surface of the vapour control layer and the insulation boards are bedded on top. Alternatively, in some situations the insulation boards may be mechanically fastened to the structural deck. The number of fixings and the application pattern is dependent upon the size and type of insulation board.

Icopal offers a range of thermal insulation boards.
Typical insulation board used: Thermazone Roofboard
