Door Folding RemaxDoors Rapid Concertina ConcealedTrack
The Concertina Rapid Folding Door by Remax Doors is a high-speed, heavy-duty solution designed for large external openings requiring wind resistance, acoustic control and operational efficiency. Featuring a twin-skin curtain with an insulating air pocket, Concertina provides improved thermal and sound performance compared to single-skin folding doors, while helping to reduce dust and energy loss.
A unique internal lateral truss system positioned between the curtain skins delivers exceptional strength for ultra-wide openings up to 12 metres. Concealed lifting straps and counterbalance systems support reliable, low-maintenance operation, with opening speeds up to 0.8 m/sec (size dependent). Designed for high wind load environments, Concertina typically achieves wind resistance ratings of up to 100 km/h, with higher ratings achievable in specific applications subject to door width and structural configuration, ensuring environmental separation and site productivity.
