Baseboard-Molding-Diagram1-300x174When it comes to properly installing Swiss Krono laminate flooring, or any brand of laminate flooring for that matter, maintaining proper expansion gaps around the periphery of the floor is critical to its success.

Why are expansion gaps necessary?

The core of Swiss Krono laminate flooring is made from high-density fiberboard (HDF). While HDF is extremely strong and durable, like any wood it’s also porous. That means that environmental factors like subtle changes in heat and humidity will cause the planks to expand and contract. Because laminate flooring is a floating floor and should never be nailed or glued down to the subfloor, it must have the ability to expand and contract, unencumbered by such vertical obstructions as walls, doorways or cabinets that can become “pinch-points” for the flooring. Without expansion gaps, you risk performance issues like buckling and squeaking of your laminate floor.

On the Flooring-Professionals.com website, you’ll find an informative article, Why Floating Floors Fail. Their excellent diagram (reproduced above) gives you an idea of what an expansion gap is. This article is written by Tim McAdoo, a certified installer. Tim shares his do’s and don’ts when it comes to installing floating floors. It’s well worth your time to check this out.

Using spacers to create a uniform expansion gap

Spacers play an important role in the installation process and should be part of your installation toolkit. Check out this video, “How to Install a Laminate Floor,” from Lowe’s Home Improvement. Note the placement of the spacers all around the periphery of the floor next to the wall. These spacers maintain a uniform expansion gap space that later will be hidden underneath the quarter-round molding when the laminate flooring planks are installed.Spacers actually are plastic wedges designed specifically for laminate-flooring installation. They often come in bags of 30 or more. You can see what spacers look like on the Zoro Tools website and a place to buy them as well. You also can buy spacers at Lowe’s or Home Depot, or almost anywhere laminate flooring is sold.

A few final words of advice on expansion gaps

At just 3/8 of an inch, an expansion gap may seem like a little thing, but don’t neglect it. Expansion gaps are part of any successful, beautiful Swiss Krono laminate flooring installation. Make sure you have them where your floor meets any vertical obstruction or where two expanses of flooring join. This will help you avoid possible buckling or squeaking of planks down the road.
