We installed this in our sunroom in 2012 . The sun room isn’t heated in the winter.We get a little seperation when the January and February extreme cold weather hits. When warmer weather rolls around it tightens right up again. We heat our sunroom on warmer winter days so we basically use it year round. This product stands up great . I would use it anywhere in my house, but my problem is I can not find it . super product if you can find it

Hi, thanks for answering so fast. I'm impressed! Tackifier was put where the planks aren't sticking good. I would like to notify the installer myself (not that he always answers) before going through you just so he doesn't think I'm trying to go above him. I'm waiting this week to see if I can get these planks to stick tight with heavy books, etc. The guy that put the tacktifier on saw that a couple planks weren't sticking good and he thought the sun coming in on them might seal them. Does that happen? Anyway, I will let you know what happens when I contact the installer again.

The only thing I can say is try to get as close to 3/4" thick with the thickest wear layer possible (as close to 6mm as possible...nothing less than 3mm). The narrow strip engineered will get you something....but less than $5/sf is risky business. You would do MUCH better with a HIGH END European Laminate for $5/sf than you would a bottom of the barrel engineered hardwood for the same price. And after that, you want to increase your budget. If you can't do that...then do what you think is best for your situation. I would prefer a high end laminate over a cheap-cheap engineered hardwood.
