PE-RT/AL/PE-RT Alpert Multilayer MLCP UFH barrier pipe for underfloor heating only

PE-RT/AL/PE-RT Emmeti Alpert MLCP Pipe

This multilayer composite pipe (MLCP)  has a total of five layers. The outermost layer and the innermost layer are made from a form of polyethylene, in this case we use PE-RT. Between these two layers sits a core of aluminium, 0.2mm thick, held in place by a special adhesive on its inner and outer surface so that all five layers  move as one. The use of a metal core  has a number of advantages. It is impermeable to oxygen so oxygen cannot pass through the pipe and enter the water, which would result in corrosion inside the heating system.  The metal core also allows the pipe to be formed by hand and retain this shape after forming. This means that it is one of the easiest pipes to bend yet requires very little securing particularly when used for underfloor heating as its weight is already supported on the insulation layer below.  The aluminium core also restricts the overall expansion co-efficient of the pipe making it less prone to sagging so it can also be used where it can be seen. This type of pipe has a relatively high maximum temperature and pressure characteristics, operating temperature 70^oC and 10 bar and is suitable for a wide range of domestic and commercial applications.
