Polycord
Introduction
Polycord, also known as Backer-rod, is a flexible cord manufactured by continuous extrusion designed to fill both static and dynamic joints. It allows the volume of sealant or mastic used to be minimized and hence reduce overall cost.
Polycord is an extruded closed cell expanded polyethylene cord which is CFC and HCFC free and does not absorb moisture. Polycord is reusable and can be 100% recycled. The expanded Polyethylene is chemically and physically neutral.
Application
Polycord can also be incorporated into side insulation and expansion joints preventing heat loss.
It can be used to avoid direct contact between walls and floating floor systems such as when using under floor heating.
Available in various diameters from 10mm – 50mm.
