Sous-plancher pour l’installation de carreaux lourds : matériaux de sous-plancher pour carrelage

Bon nombre des tendances de plancher les plus populaires dans la construction et la rénovation de maisons neuves sont les carreaux de sol lourds en porcelaine, en céramique et en pierre. Bien que ces produits promettent une durabilité à long terme, il est important que vous portiez une attention particulière à la construction du sous-plancher afin de minimiser les dommages à long terme. Jetons un coup d’œil aux supports de revêtement de sol à panneaux de lamelles orientées pour les carreaux et aux meilleurs matériaux de sous-plancher pour les carreaux.

Examples of Heavy Tile

You've likely seen an increase in large format and heavy floor tiles with your luxury and custom homebuyers, such as porcelain and ceramic tiles. While they are made from different densities of refined clay, in general porcelain and ceramic tiles are much heavier than more mainstream floor coverings. That's why additional consideration needs to go into the design of floor systems that include ceramic, porcelain or stone tile.

How to Decide on Materials for Sub-Floor?

It's critical to have homeowners choose design materials in the early planning stages of construction so you can prepare the structure accordingly. 

For example, a commodity OSB sub-flooring is adequate if the homeowner chooses a budget-friendly vinyl, laminate or carpet. The weight of these common floor coverings is minimal compared to ceramic and porcelain tile or stone, which can be significantly heavier, especially considering that a backer board is also typically used.

By laying down natural stone or similar luxury tile and adding heavy furniture, you can quickly exceed the capacity of the sub-floor and the floor system. Without proper design, a floor system with commodity OSB sub-flooring for tile may experience excess deflection, cracking grout and tile and even separating the bond between the tile and the backer.

To minimize deflection, especially under heavy natural and porcelain stone, the best sub-floor for tile is a premium one. For example, LP Legacy® Premium Sub-Flooring is one of the toughest sub-flooring panels in the industry. The panels offer enhanced bending properties which, when adhered to properly designed floor joists with LP Legacy Premium Sub-Floor Adhesive, can result in less deflection of the overall floor system, protecting expensive floor coverings. And the greater strength of LP Legacy panels can help support heavy point loads like the legs of a piano.

Remember, always refer to floor design recommendations often provided by the industry association for the particular floor covering being used.

Subfloor Thickness and Materials for Tile

So how thick should the sub-floor be for tile? “It's not necessarily about thickness, it's about stiffness,” says Kelly Harmon, Senior OSB National Product Manager at LP Building Solutions. “For instance, a 23/32˝ LP Legacy Premium Sub-Flooring is 77 % stiffer than a 19/32˝ panel of the same material placed in the same support system. Thickness greatly influences stiffness and subsequently deflection. Additionally, stiffness increases proportionally to the cube of the material's thickness.”

LP Legacy Premium Sub-Flooring is a super-durable, premium panel designed for demanding sub-floor applications that require exceptional stiffness, providing the density and stability needed to support heavy stone and ceramic floors, exotic hardwoods and other heavy flooring options.

Preventing Uneven Sub-Flooring

An uneven floor can leave tile and stone partially unsupported which can quickly damage these expensive floor coverings. That's why it's important to choose a product designed to remain uniform, consistent and level. One of the benefits of using an option like LP Legacy Premium Sub-Flooring is its consistent, high-quality finishes. "LP Legacy sub-flooring has a full sand, which promotes uniform thickness. The transition between the panels in the profile and end joints is smooth. This helps avoid any elevation or step changes that could create a stress point under the tile," says Harmon.
