How to judge the quality of flooring

The best flooring conditions:

1, economic: economic benefits, low construction costs, a large range of floor prices.

2, "five not": no discoloration, no deformation, no cracking, no insects, no mildew.

3, environmental protection: no formaldehyde and harmful gas release, noise reduction, no smell.

4, "four resistance": wear, stain resistance, impact resistance, acid and alkali.

5, cleaning: antibacterial, easy to clean and maintain.

6, comfort: soft and comfortable, carpet feeling.

7, personalized: rich colors, realistic, in line with the requirements of personalized design.

8, Applicability: Wide range of applications, not afraid of humidity, temperature changes, dimensional stability.

9, security: fire grade B1 level, light floor, reduce the building's carrying capacity.

The floor that satisfies the above 9 conditions is the best floor. From the current production floor to see solid wood flooring, laminate flooring, bamboo flooring can not fully meet the above conditions, only the PVC coil floor, said the only accurate point is only compound PVC flexible coil floor to fully meet the above 9 One condition, ordinary PVC sheet flooring (stone-plastic flooring), homogenous PVC floor rubber flooring cannot meet the above conditions.

The classification of fire protection standards for building materials:

China's national standard GB8624-97 divides the combustion performance of building materials into the following categories:

Class A: Non-combustible building materials: Material that hardly burns.

B1 level: difficult to burn construction materials, flame retardant materials have good flame retardant effect. It encounters fire in the air or is difficult to catch fire under high temperature. It is not easy to spread quickly, and the combustion stops immediately after the fire source leaves.

B2 level: flammable building materials: combustible materials have a certain degree of flame retardant, in the air in case of fire or under the effect of high temperature will immediately start burning, easily lead to the spread of living, such as wood columns, wooden trusses, wooden beams, Wooden staircase and so on.

Class B3: Flammable building materials: No flame-retardant effect, extremely flammable, and high risk of fire.

The national fire protection rating for PVC flooring must be B1.
