Inverted roof deck insulation.

Jablite inverted roof insulation is a unique innovative closed cell expanded polystyrene eps with low water absorption properties kiwa certified bar 19 098 s a uk suitable for use on flat roofs with zero pitch and slopes up to 10 resistant to the effects of freeze thaw. Rigid extruded polystyrene insulation has minimal water absorption due to its closed cell structure. One of the main benefits of the inverted roof method is that the membrane is protected by the insulation from the expansion and contraction caused by weather fluctuations such as frost and solar radiation. Invented by dow in the late 1960 s an inverted roof system uses dupont styrofoam brand xps insulation to protect the membrane helping improve the performance and longevity of the entire roof system.

It is also protected from damage by traffic on the roof such as people walking the movement of equipment and so on. An inverted roof is quite simply where the waterproofing layer is installed over the structural deck rather than over the insulation. This makes it the only material suitable and approved for inverted roof applications.
