I have inspected a few of these installations where it got too hot and the planks seperated and did not stay together. I just did about 1200 ft of this stuff.
Now try and do this at 70F. You can't. But you can at 85F.
Oh yeah, there was no AC anyway. See that box on the roof? That my friends is an evaporative cooler, also known as a swamp box. And see that hill in the background?
Allure is the bottom price point/quality being sold by Metroflor to HD. The bottomline for private dealers is Country and is supposedly slightly better quality then the Allure line but with only a few skus.
Both aren't worth the money in my opinion.
And yes they are temp sensitive. Climate control is needed.
