PVC flooring, as a kind of modern floor decoration material, is widely used in many places such as home, office, hospital, school, gym and so on because of its environmental protection, wear-resistant, non-slip and other characteristics. According to the different primer layer, PVC flooring can be divided into two types: dense bottom and foam bottom. This article will detail the difference between these two types of flooring to help consumers better choose the right floor for themselves.

Structure and material

Foam bottom PVC flooring: In the production process, through the addition of foaming agent, so that the bottom layer of the material presents a fluffy, soft characteristics. This design not only gives the floor good elasticity, but also has a superior noise reduction function. Foamed subfloors are softer on the feet and have a lower risk of falls and injuries. However, they are more likely to leave indentations when heavy objects are placed on them, although these indentations are usually quicker to recover.

Dense-substrate PVC flooring: Dense-substrate, which has not been foamed, has a denser structure and a harder floor with stronger compression properties. Dense-substrate flooring is less likely to leave indentations on the surface, making it more suitable for use in public areas. In addition, dense-substrate floors usually have higher abrasion resistance and anti-slip properties, and can better withstand the pressure and wear and tear of daily use.

Performance characteristics

Abrasion and pressure resistance: Dense-sub floors are more durable than foam-sub floors in terms of abrasion and pressure resistance, making them suitable for hospitals, factories and other public places. Foam subfloor is less expensive, but it is easy to leave indentation marks under the long-term pressure of heavy objects.

Resilience and noise reduction: Foam flooring is more suitable for places that need good footing and noise reduction, such as kindergartens, fitness centers and early learning centers, due to its good resilience and noise reduction function. Dense subfloor has a relatively poor noise reduction effect and is not as soft as foam subfloor.

Moisture and heat resistance: Dense subfloor has a fiberglass layer in the middle, making it dimensionally stable, and not easy to deform and rot in warm and hot environments. Foam flooring also has a certain degree of moisture resistance, but in extreme environments may not be as stable as the solid bottom.

Price and environmental protection: Due to the lower density of the foamed subfloor, the material used in the production is relatively small, so its price is usually slightly lower than the dense subfloor. However, in terms of environmental friendliness, both meet environmental standards, and their non-toxic, waterproof and non-slip characteristics make them suitable for a wide range of locations that require a safe and healthy environment.

Appearance and Identification

The thickness of PVC flooring underlayment occupies at least 2/3 of the total thickness of the flooring, so it is easy to distinguish between the foam bottom and dense bottom PVC flooring in terms of appearance. Foam bottom of the primer layer side fluffy, there are many different sizes of bubble holes; and dense bottom of the primer layer dense, can not see the bubble holes. In addition, you can also use your fingernails to pinch the bottom back of the floor, foam bottom is easy to leave traces and quickly recover, while the dense bottom is very difficult to pinch and not easy to leave traces.

Application Scenario

Because of its good elasticity and noise reduction function, the foam floor is more suitable for places that need comfortable feet and a quiet environment. Dense subfloors are more suitable for areas that need to withstand heavy pressure and frequent stepping due to their excellent abrasion and compression resistance. For example, in a gym, it is best to choose a dense subfloor for areas where heavy equipment such as treadmills are placed; while corridors, yoga areas, and other places where people are active can choose a foam subfloor.

Summarize

Dense bottom and foam bottom PVC flooring have their own unique advantages and applicable scenarios. When choosing, consumers should decide whether to choose foam or dense bottom according to the specific needs and environment. Whether you are looking for comfort or durability, there is always a PVC flooring that can meet your needs.
