Knowing what R-value and U-values mean is key to following energy issues and to selecting products that best suit the climate zone you are building in. R-value is essentially a product’s resistance to heat flow. Adversely, U-value measures the rate of heat transfer. This means that products with a lower U-value will be more energy efficient. It is tempting to think that these two values are direct opposites of each other, but there are some important differences to note.
Knowing the moisture content of your OSB sub-floor panel is an important indicator on whether to proceed with other stages of the build, especially if hardwood flooring is the next step. You need to know that using a moisture meter doesn’t give very accurate measurements with OSB or other glued products.
OSB structural wood panels can be installed over concrete slab floors for both commercial and residential applications. The panels can be installed directly onto the concrete slab, oversleepers which are installed onto the concrete slab or over rigid foam insulation.
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.
