I had no idea linen insulation existed, was nice to learn something new :) It may be more expensive, but if you can afford it I think it is a good choice, because the traditional insulation gave my brother allergies that till this day (2 years have passed) he could not get ride off. It was because of a job he did once, where he applied insulation in a roof without protective mask... Since then I am very careful with this stuff. It was a good choice of you, better pay a little more in material than a lot in health.
