Commercial Metal Roofs
E-therm has been designed especially for commercial and industrial roof systems. Being so thin and light the installation process makes it one of the easiest products to install, With the innovative foil flap, E-therm eliminates taping and overlapping on the longitudinal side of the roll. What this also eliminates is loss in square meters per roll when installed. This saves on added cost for extra material that is doubled up and also eliminates a bowing effect that also can be caused from overlapping. The 8mm product also meets the thermal break requirement that has now seen to be mandatory in most of these types of applications. E-therm in systems meets the J section requirement that is also set by the BCA.  

1. Roll and lay E-therm insulation perpendicular to the purlins ensuring a minimum of 100mm overhang into the guttering.
2. Allow a nominal sag between the purlins, naturally this will be around 20-40mm.
3. Make sure that the E-therm insulation is butted tightly longitudinal and the 150mm foil flap overlap runs is installed on the top of the product to eliminate water penetration.
4. All end joins should be taped or overlapped, the tape used should be supplied by Reflex and have a minimum thickness of 72mm.
5. Fix roof sheeting by screwing through the E-therm insulation to the metal purlins as per normal.
