Aluminum foil at the back of hardwood floor?

Question

I have just purchased 1000sqft of hardfloor and planning to install it today. When i opened the boxes, there are thin aluminum foil sticked on the back of my floor pieces.

do i need to peel them off? or just leave them on. Thanks

Answer 1

leave them on. that is there for people who have radiant heat in the floor. it helps to distribute the heat more evenly across the floor while protecting the wood.
