When moving from a 3/4" hardwood floor to a thinner product such as engineered or laminate which is usually 8mm or 12mm, do you typically want to offset the lower profile of the new product by installing an additional layer on the sub-floor in order to bring the level up snug under existing door frames, etc?
Quick calculations show 12mm to be a little less than 1/2" so it seems like I'd be able to layer 1/4" sheets of plywood directly on top of the existing 3/4" plywood sub-floor so that by the time I add any underlay and then the new product on top I should be at the same height as the old hardwood.
Am I thinking about this in the wrong way? I don't want to re-frame all my door casings to be lower just to avoid gaps between the bottoms and the floor and obviously slapping quarter round on the bottom of the jamb / casings is not feasible so raising the sub-floor seems to be the best option to me.
Thanks in advance for your answers / help. Glad to have found this site - I've used Stack Overflow for years as a software developer and it looks like there are just as many knowledgable, helpful folks over here.
