Product Overview:
Engineered for efficiency and longevity, the Maincor 20x2.25mm Pre-Insulated MLCP is the ideal choice for installations where energy conservation and temperature control are critical. The integrated 9mm insulation layer helps meet Part L of the Building Regulations by reducing heat loss from pipework in unheated spaces such as voids, basements, and roof areas.
The pipe’s aluminium core provides dimensional stability, allowing it to maintain its shape while resisting expansion and contraction. Combined with its corrosion resistance and low thermal conductivity, this pre-insulated MLCP ensures reliable performance in both heating and potable water applications.
Typical Applications:
Underfloor heating systems
Central heating pipe runs
Domestic hot and cold water supply
Secondary circulation systems
Installations through unheated spaces
