Expansion and contraction of your flooring system is a given. Because they are manufactured from different materials or different kinds of the same material, your flooring and substrate will expand and contract at different rates. Expansion joints give your flooring the space it needs to expand without buckling or cracking.
Drywall Carts are used to ferry materials around construction job sites. When these carts are overloaded and traverse wood sub-flooring panels, they can cause damage, especially when these panels are wet from exposure to the elements.
While you should always adhere to the manufacturer’s installation instructions, there are some general guidelines provided by the NWFA that apply to most subflooring installations. There are a number of subflooring options available and you can speak with your design professional to find one that suits your climate, needs and budget.
Hardwood can make for a durable and beautiful floor, but small mistakes in the subflooring or installation can wreak havoc and buckling, squeaky, uneven floors can all result from poor installation. While this is not a definitive guide to hardwood installation over OSB panels, there are some important points to ponder.
Floors expand and contract with changes in moisture, heat and season. This movement can pull tiles apart creating cracks or push them together so that they pop up or ‘tent’. Proper planning and preparation of the subflooring will help to prevent tenting and cracks in tiled bathroom floors.
If you are getting callbacks for uneven or squeaky floors, make sure that you are correctly spacing your OSB subflooring panels. Wood expands or contracts with changes in moisture conditions and without proper spacing, the panels can push together and this causes the edges to lift which, in turn, causes the squeaks and bumps.
