K-FLEX ST ALU Elastomeric Insulation Sheet – Rolls
K-FLEX ST ALU is a self-adhesive closed-cell elastomeric foam sheet with a factory-applied aluminium foil facing. The ALU facing provides a durable, vapour-tight outer surface that is resistant to mechanical damage, UV exposure, and condensation — making it the premium choice for exposed pipework, ductwork, and plant room applications where a professional finish is required without additional cladding.
Supplied in roll format across thicknesses from 6mm to 32mm, ST ALU combines the thermal and moisture performance of K-FLEX ST with the protection and aesthetics of an aluminium facing.
