high-performance insulated rapid roller doors specifically engineered for food production facilities, refrigerated warehouses and cold-room environments.

DESIGNED FOR HYGIENE, TEMPERATURE CONTROL & OPERATIONAL EFFICIENCY
BK Doors offers high-performance insulated rapid roller doors specifically engineered for food production facilities, refrigerated warehouses and cold-room environments. Whether you require doors from Dynaco or Cool-It, our systems deliver speed, insulation and hygiene on a high-spec level.
In the food and cold-storage sector every second of delay and every degree of temperature variation costs you. Our insulated rapid roller doors are built to tackle these challenges. Sourced from leading brands like Dynaco and Cool-It, these doors combine fast open/close cycles, insulated curtains and fully sealed frames to maintain ambient control, reduce contamination risk, and minimise energy loss. For freezer zones, ambient cool-rooms or food processing lines, these doors are ideal to integrate with your workflow, hygiene protocols and temperature control standards.
MINIMAL AIR EXCHANGE
Fast-acting door cycles reduce exposure of cold zones to external air, driving down energy loss and helping maintain temperature stability.
EXCEPTIONAL THERMAL PERFORMANCE
Insulated curtains with optional heating elements and full-perimeter seals ensure minimal thermal bridging and reduce ice/condensation build-up
HYGIENIC & EASY TO CLEAN
The hygiene-rated construction, smooth surfaces and corrosion-resistant hardware meet the stringent demands of food industry and cold-room environments.
AIR-TIGHT & PRESSURE STABLE
High-cycle performance paired with airtight design keeps pressure differentials under control, safeguarding clean zones, chilled spaces and production line integrity.

Frequently asked questions
Selecting the right insulated rapid roller door system for cold storage, food production or processing surfaces is a critical decision for operational efficiency and regulatory compliance. Below, you’ll find answers to some of the most common questions about our Dynaco and Cool-It door solutions.
What cycle speed can be expected?
Depending on model and size, high-speed rapid doors open at up to 2.5 m/s, significantly reducing air exchange in cold-rooms.
Are these doors suitable for freezer-/-25 °C applications?
Yes – with insulated curtains, heated frames and full-seal designs, certain models are built specifically for sub-zero environments.
How important is the seal for hygiene and hygiene standards?
Critical. An airtight seal prevents warm air ingress, ice formation and contamination risks — especially in food-industry and cold-storage zones.
Can I retrofit these doors into an existing cold-room opening?
Absolutely. We provide options for retrofit with minimal disruption and tailored specification to site conditions.
Which brands do you supply and install?
We supply premium systems from Dynaco and Cool-It — both trusted for food, cold-storage and high-cycle environments.
How is maintenance handled for high-cycle doors?
High-cycle environments require regular maintenance (quarterly or bi-annual) to verify curtain tension, sensors, seals and operational performance.
