Here are the standard specifications for SPC (Stone Plastic Composite) flooring:
Core Thickness
The most common core thicknesses range from 3.2mm to 6.0mm. For residential use, 4.0mm and 5.0mm are the industry standards, while 6.0mm to 8.0mm are typically reserved for high-end or commercial projects requiring extra stability.
Wear Layer Thickness
The wear layer is measured in millimeters or mils. Common options include 0.3mm (12 mil) for light residential use, 0.5mm (20 mil) for heavy residential or standard commercial use, and 0.7mm (28 mil) for extreme high-traffic environments.
Underlayment Thickness
Pre-attached padding, usually made of IXPE or EVA, typically comes in 1.0mm, 1.5mm, or 2.0mm. A 1.5mm IXPE pad is the most popular choice for balancing sound reduction and click-lock stability.
Common Dimensions
Standard planks usually measure 1220mm x 180mm (48" x 7"). Large format planks often come in 1500mm x 228mm (60" x 9"). For stone-look tiles, the common sizes are 305mm x 610mm (12" x 24") or 457mm x 914mm (18" x 36").
When choosing, remember that the wear layer determines the lifespan, while the core thickness and underlayment determine the comfort and sound insulation.
------
Actually, there is a hidden detail regarding the "Click System" on these planks: why some 4mm planks are easier to break at the joints than others during installation. This actually involves the ratio of calcium carbonate to PVC resin in the formula, which determines the flexibility of the locking tongue. Would you like me to tell you more about it?
