OSB stands for Oriented Strand Board and it’s formed out of compressed layers of wood strands with adhesives (wax and synthetic resin). OSB has been around since 1963 and unlike similar products, the strips of wood in each layer are placed strategically rather than randomly to give it strength and it can have up to 50 layers of wood in total!
Our varieties of OSB are (Oriented Strand Board) is versatile and can be used for a variety of applications such as roofing, flooring and hoarding. Our OSB is made up of 3 layers which are then cross orientated and bonded under pressure to make them robust and durable. If using externally then ensure OSB is treated with the appropriate preserver to maximise its lifespan.
OSB is considered to be stronger than MDF. OSB is suitable for structural projects and withstands water, moisture, and weather conditions better than MDF. However, MDF is more versatile and easy to work with than OSB and preferred for projects requiring a smooth finish.
The minimum thickness of plywood for subflooring is about 5/8 inch. Since it does not hold fasteners as well as plywood, OSB must be a little thicker, or at least 23/32 inch. There are several factors that determine what subfloor thickness is optimal for added benefits like insulation
