Difference Between Directional & Non-directional Homogeneous Flooring
Homogeneous flooring is a single layer 2*20m vinyl sheet, whose pattern is consistent throughout the whole thickness. Even if the surface is worn or scratched, pattern keeps the same after being polished.
Homogeneous flooring can be divided into 2 types: directional homogeneous flooring and non-directional homogeneous flooring.
Directional and non-directional are distinguished from the pattern. Pattern of directional homogeneous flooring has vertical stripes, which looks like drawn flower shape. As it has an obvious directionality, it can only be paved in one direction during installation. Or there will be color mismatch and other phenomena.
Non-directional surface pattern is the distribution of gravel particles with different colors, there is no directionality. There is also no difference if pave in different directions.
Except patterns, there are more differences between directional and non-directional homogeneous flooring.
Production of directional homogeneous floor is a one-time molding process, while the non-directional type is a multiple molding process.
The one-time molding process(directional type) is simple and fast, floor density is high. The multiple-time molding process(non-directional type) is more complicated, floor density will decrease, which greatly improves the wear resistance and extends floor’s service life.
Raw material difference
The main raw material of homogeneous flooring is polyvinyl chloride resin, mixed with other additional ingredients such as carbon powder, stabilizers, plasticizers, pigments and other auxiliary materials.
Proportion of PVC in non-directional type is higher, which brings lower weight but higher strength. Weight of non-directional type is 2800-3000g/m2(2mm thickness), wear resistance can reach P or T grade. Weight of directional type is around 3200g/m2(2mm thickness), wear resistance is P or lower grade.
Due to the production difference, PVC raw material content, wear resistance grade,etc, non-directional type has better performance in product performance.
In actual application, non-directional type is also more widely used. We have more than 20 collections of non-directional type, you can always find the pattern and color you prefer.
Price of directional type can be much cheaper than non-directional type, currently we have 2 collections. In some projects with low traffic, non-directional type is a good choice.
