Installation
MegAtec 610 is supplied as A01 (roof to roof) and A02 (roof to wall), which use different blockout and sightline dimensions — A01 blockouts run 120–488 mm across the gap range, A02 runs 68–470 mm. Because the correct detail depends on the junction and your roof build-up, send us the gap width and movement requirement and we will return the CAD detail and product reference.
Applications
The MegAtec 610 on our projects
Six of our written-up projects use the 610.
A clause written to the MegAtec 610 data sheet
Worked for a 100 mm roof joint. Change the gap and the movement for each location on the joint schedule and leave the rest. It names what the joint must do rather than who makes it, so an alternative has to match the performance, not just the description.
Each requirement is explained in how to specify an expansion joint. Writing to a CPWD tender? See the DSR items. See also expansion joints in buildings and the types of expansion joint.

Choosing between systems comes down to where the joint sits, how much it has to move and what runs over it. These are the nearest alternatives to this one.
