TimberHP installation struggles – GreenBuildingAdvisor

We got our TimberHP batt insulation delivered. I’ve never installed any kind of batt insulation, but I’m wondering is it normal to have to force the batts into the stud bays? Our studs are 16OC and the batts are 15”. We really have to press the sides and use a lot of muscle to get the batts in place. In installation videos I’ve seen for TimberHP the batts fit easily between the studs without too much force. Is there something I’m missing? Do I really need to trim every batt down just to not have to fight it into the stud bay? That would be so wasteful.
