Design and Installation of Sprung Maple Wood Floors

Foam Blocks

• Most modern sprung floors are constructed by gluing blocks of closed-cell, high-density foam at even intervals on each wood plank’s back of. Closed-cell foam is foam without pores, giving it more structure than open-cell foam. The planks are interlocking and easily fit together. When assembled, the wood dance floor sits an average of 1 ½ inches off the subfloor. The sprung floor’s exact construction suspended by foam blocks differs among various manufacturers.

Other Construction Methods

• Although not as common, there are other construction methods used for sprung floors. A closed-cell foam mat is sometimes rolled out under a wood floor, but provides less give than using separate blocks of foam. Replacing foam blocks with thick, rubber strips is another option. Traditionally, sprung floors were made using small wooden planks and a basket weave pattern. This method is no longer used, as the floors were not very durable.

Preparing for Installtion

• Thoroughly clean the substrate where you'll be installing your sprung floor. It needs to be free of all dust and debris. Ensure the substrate is level and doesn't have any dips or lumps. Suitable substrates include concrete, vinyl, laminate and tile. If you are installing directly over concrete, laying a barrier of 6 mil plastic protects the sprung floor from moisture. Wood floors expand and contract with changes in moisture, so leave a one-quarter inch gap at each wall per 10 feet of flooring. For example, if your floor extends for 20 feet, leave a one-half inch gap between the floor and each wall.

Installation Basics

• Carefully read and follow the instructions provided by your manufacturer. They have accounted for the specific construction of their floors. Neglecting to follow their instructions could result in failure of your floor. Failing to follow directions may also void your warranty. Sprung floors are tongue-and-groove floating floors. Insert the tongue from one plank into the groove of the plank in front of it, and then gently press or tap them together. Place a wood block against the plank’s free end and tap it with a hammer until the tongue on the other end slides into the groove of the plank next to it.
