Ever wondered what all that information on your OSB sheathing panel means? That information is vital to construction professionals and helps them to understand how to store and use the material. Here’s a rundown of what the grade stamp on Norbord products represents.
As much as 95% of US roofing starts with wood panel sheathing. This is because it’s easy to work with and provides a sturdy substrate for roofing materials. However, if the wood sheathing panels are not installed correctly, bucking may occur and this will telegraph through to the shingles causing a ‘wavy’ look. This can result in very expensive call backs for the construction company, so ensure that you follow these guidelines and the manufacturer’s instructions as well as your design professional’s outlines in order to avoid problems.
