I have a rough opening in my garage that is 1.017 m (40 inches) wide. For installing a Hörmann MZ door with a 1 m (39 inches) width, I was told that I need a larger clear width if I want to install it "according to the state of the art" using compressible sealing tape (Kompriband). It was suggested that I could grind off the "protrusions" (tongue and groove) of the Poroton blocks. Now I’m not sure whether I should do that or choose the option "installation: foam sealed" instead. I definitely don’t want to spend an extra 300 EUR to go for the next narrower door size instead of 1 m.
This concerns a secondary garage door to the garden.
Is it acceptable to simply remove these "protrusions"?
And why isn’t nearly 1.02 m (40 inches) of width sufficient to install a door with an order size of 1 m (39 inches) "according to the state of the art"?

If the rough opening nominal size 101 is measured 7 mm (0.28 inches) too large only at the valley of the interlocking joint, it will actually be measured slightly too small—probably by about the tooth depth. I would say a general contractor’s versatile construction mechanic would solve this without hesitation using an angle grinder. However, I also expect quite a bit of chipping to occur. I’m not sure whether you could effectively control the breakout by clamping the reveal between plywood panels with clamps. Please report back on how much the chipping turned out to be. May the Force be with you (and your safety goggles)!

I’m not going to tackle that with an angle grinder. That would mean a total cutting length of 17 meters (56 feet). Plus, the Poroton is too crumbly for that. I will order the installation done the "traditional" way.
