Telescope thermal sensitivity (for focusing)

Is there a difference in thermal sensitivity for different telescope designs?
I have a refractor and I need to constantly refocus if the temperature changes.
Do some telescope designs have more thermal resilience?
eg Cats vs Refractors vs Newts vs RCs etc...
Maybe the only answer is to get carbon fibre tubes?
