Indoor Delight SPC flooring is a modern and durable option that combines the best of both worlds: natural wood's beauty and vinyl's practicality. What sets stone polymer composite vinyl flooring apart from other flooring is the nature of its core. It's composed of multiple layers, including a rigid core made of stone polymer composite (SPC), which gives it incredible strength and stability. This is what provides the rigidity and stability for the plank, different from the flexibility of other vinyl flooring. Because SPC tends to be thicker than other vinyl floorings, it adds more support underfoot. This also makes it look even more similar to natural hardwood flooring, including having the same denser feel and ability to retain heat and does better in areas with direct sunlight. Lastly, a pre-attached underpad provides higher sound insulation and cushioning. You may also hear that SPC is made of Stone Polymer Composite.
