Fully Adhered Method of Single Ply Roofing Application

Fully Adhered Single Ply Roofing Systems

Fully adhered systems are suitable for most applications particularly where improved aesthetic appearance or complex geometry are important design factors.

In fully adhered single ply roof 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.

Key

  1. Sureplan FPO Fleeceback.
  2. Icopal Single-Ply Membrane Adhesive.
  3. Thermazone insulation board.
  4. Icopal Insulation Adhesive.
  5. Vapour Control Layer.
  6. Structural deck.

Sureplan FPO Fleeceback single ply membrane is secured to the insulation boards using a special cold applied adhesive. The adhesive is spread across the insulation boards and the Sureplan FPO Fleeceback membrane which is then rolled into the adhesive. The adjacent sheets of roof membrane are positioned to allow for 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
