ᐅ Wall connection to wooden beam

Hello everyone,

I am planning to build a non-load-bearing partition wall in my attic using 8DF Poroton bricks (11.5 cm (4.5 inches) thick).
For lateral stabilization against tipping, I am considering attaching the wall to the surrounding wooden structure (roof frame) with a sliding connection.

Planned execution:

• Secure heavy-duty brackets firmly to the wooden beams
• Connect to the masonry only with a sliding joint (large central hole in the bracket, screw with large washer, not tightened, about 1–2 mm (0.04–0.08 inches) clearance)
• No rigid connection between wood and masonry

Background:
The wall currently stands in front of the neighboring exterior wall (stone wool insulation behind it).
In a few years, the neighboring wall will be demolished (for an extension), so I want to build my 8DF wall in such a way that it remains stable and resistant to tipping even without that rear wall, and without generating internal stresses due to wood movement.

Question:
From your perspective, is this sliding connection for stabilization reasonable and technically correct?

Thank you very much for your input!
