Combi Panel

OTM International is now presenting the first composite system in Turkey with rock wool insulation and membrane which is fast and easy.
Generally at flat roofs where rock wool is chosen as insulation material, combined roofing applications are used widely. Upon the surface created by corrugated sheet layers, vapour barrier and rock wool insulation layers are used under water isolation membranes. For the application and maintenance of this system, a rock wool insulation layer with minimum 150 kg / m3 density has to used in order to resist live loads. This makes the application expensive, difficult and takes long time.

Combi Panel can solve all these problems at once. OTM International started the production of “Rock wool Insulated Panels with Membrane” at continuous processing line. With the use of this product, layer application stages in combined roofing systems are eliminated, thus providing savings in material, workmanship and time.

The spaces under corrugation in Combi Panels are filled with rock wool, unlike combined roofing applications where these spaces are left empty. The advantages of this system of Combi Panels is that, during fire the hot gasses will not be collected in these empty spaces and rate of fire expansion will be slowed down (according to DIN V 18234-3). In addition the sound insulation values are improved.

The durable polyurethane layer on top, which resists live loads, provides the workspace for workers and protects the fragile rock wool from chipping or breaking apart during transportation.

Additional use of screws to attach membranes to panels are also eliminated, panels are simply attached to the purlins or to the structures according to panel application specifications.
