IDENTIFICATION
Introduction
This booklet provides guidance for site activities
necessary to prepare, install and commission
Dunham Strip radiant panels. The instructions apply
for standard product only; please study them
carefully before commencing any installation work.
Description
Dunham Strip comprises aluminium sheet panels
with steel pipe clamped to the upper surface. The
pipes are located in a groove in the panel to
maximise the physical interface between pipe and
panel, ensuring efficient heat transfer to the
radiating surface. The panels have a durable
coating of epoxy polyester powder, and are fitted
with insulation to minimise heat losses above the
panel.
