High speed roll doors specialist DMF International advises buyers of high
speed insulated doors how to make the right selection.
High speed insulating doors are increasingly being adopted across Australia.
Offering greater thermal and sound insulation than conventional PVC rapid roll
doors, these doors are deal for busy areas that require both speed of operation
and preservation of temperature.
Buyers of high speed insulated doors need to be careful when making
their choice because not all doors available in the Australian marketplace have
the same qualities. When selecting a high speed insulated door, the buyer must
enquire about: the thermal properties of the door in its entirety, and not just
that of the door slat; door design utilised to prevent temperature conduction
via the door slats; quietness of operation; and whether the door is counterweighted
for emergency opening.
Some door models in the high speed insulated range have a roller shutter
design, using a 10mm thick slat filled with PU foam without interslat thermal
protection. This design may suit environments with low thermal differential,
but may not perform well as a long term solution or with quietness of
