High speed roll doors specialist DMF International advises customers
looking for high speed insulated doors to be careful when making their
High speed insulating doors are increasingly being installed in
Australia for the advantages they deliver in busy industrial and commercial
environments that require both speed of operation and preservation of
High speed insulating roll doors offer greater thermal and sound
insulation than conventional PVC rapid roll doors. However, not all insulating
doors available in the Australian market offer the same benefits.
For instance, some insulating door models may have designs similar to a
roller shutter door, using a 10mm thick slat filled with PU foam without interslat
thermal protection. This design may work in places of low thermal differential,
but will not perform well as a long term solution or offer quietness of
4 questions to ask when selecting
a high speed insulated door:
1. What are the thermal properties of the door in its entirety, and not
just the door slat?
2. What design does the door utilise to prevent temperature conduction
via the door slats?
3. Will the door be able to operate quietly?
4. Is the door counterweighted for emergency opening?
