A. There are several reasons why floors make cracking sounds:
Relative humidity: Ensure that the relative humidity in your house is neither too high nor too low. This may explain why your floor loosens and becomes noisy. A humidity rating between 37% and 45% is ideal.
Wrong type of subfloor: For nailed flooring, the subfloor must be made of plywood or OSB panels; the use of particleboard is not recommended.
Wrong subfloor thickness: The recommended panel thickness is ¾ inches (plywood or OSB) for joists spaced apart 19 inches or less, centre to centre. Spacing exceeding 19 inches or a greater span can result in deflection, leading to cracking sounds.
Board direction: Boards are installed in the same direction as the joists.
Structural weakness: The subfloor is not firmly anchored to the joists with flooring screws; there are gaps between the subfloor and the joists.
Lack of anchors: When boards are not anchored securely, they may move and lead to cracking sounds. Each board must have a minimum of two nails two inches from board ends, ideally spaced at eight-inch intervals in relation to the board length.Read more »
A. This phenomenon is due to a variation in the internal humidity of the wood. This is not related to a defective product. It is caused by environmental conditions.
There are several reasons for changes in humidity:
Humidity too high in the subfloor or a very damp basement: The underside of the board absorbs more humidity than its top side, resulting in unequal swelling between the underside and top side of the board and the cupping effect.
Leaks or water spilled on the floor: Water infiltrates between the boards and is absorbed by their undersides. This results in swelling on the topside and the cupping effect.
Relative humidity too high: During very humid periods, the wood absorbs humidity from the ambient air and expands. Since the boards are anchored to the floor they cannot expand freely and press against each other, causing cupping. Insufficiently large expansion joints can exacerbate the problem.
A stable climatic environment in the house is the key to the optimum stability of wood flooring. Refer to our installation guide, in the documents section, for more detailsRead more »
A. Although we use the terms hardwood in English and bois franc in French, this does not make your flooring a product resistant to all kinds of marks caused by dropped objects or even high heeled shoes.
Each species has its own characteristics. Some withstand compression better than others. Wood hardness is measured with the Janka test.Read more »
