Hardwood Flooring and Expansion Gaps

When installing hardwood flooring, it is important to take into leave room for expansion gaps. Hardwood floors, like any other wood reacts to moisture. In humid conditions the wood absorbs moisture and expands. Conversely in dry weather the moisture is released and the wood tends to contract. If gaps are not left and the flooring butts up against the walls, when the flooring expands there is every possibility it will buckle. Expansion gaps are gaps left around the perimeter of the flooring and the baseboard of the walls to allow for this swelling and shrinkage. Recommended expansion gap width is between 3/8” and 3/4”, which can be covered using additional shoe molding or the original baseboard. As a thumb rule, the smaller the room the less the gap required.

The expansion of hardwood flooring will vary from one species to the next. Another contributing factor is the way the wood is cut and the amount of humidity in the atmosphere. In general, solid hardwood expands and contracts more than engineered wood flooring. Engineered hardwood is built in layers which helps to reduce movement. No matter if you are installing engineered hardwood floors or solid wood flooring, always remember to leave room for expansion gaps.

To prevent Hardwood Flooring from gapping or the opposite cupping you need to do a few things.
#1 Know what the humidity levels are in the home before you deliver the wood flooring and what the recommended levels should be. #2 Ensure that the humidity levels are kept within those parameters to prevent these problems once the floors are installed.

after hardwood flooring is installed the polish and shine is lost and there is gap between joints and if we fill that it looks very odd.

That gorgeous hardwood look can also be recreated with bamboo flooring. This sturdy grass has exploded in popularity as an alternative to harvesting trees due to its rapid renewal rate. Bamboo is considered a highly sustainable resource since it can regrow in only three years (and doesn’t need to be replanted), whereas a tree will take from 10 to 60 years to grow again.

Absolutely right. A certain gap is always needed to prevent such floor buckling. I think engineered hardwood can be effective for this kind of weather changing problem.
