Multispan Tunnel

Several tunnels joined into one structure with no plastic between them, so one heating system can serve them all.

About the Multispan Tunnel

Multispan tunnels are multiple structures joined together. They share one structure on the inside and are not separated by plastic between the tunnels.

The benefit is that one heating system can be used for several tunnels. Multispan tunnels are designed for commercial use.

Standard multispan sizes are 20 m x 30 m and 30 m x 30 m. Larger layouts are designed to order, up to 100 m x 100 m multispan.
