SPC Flooring for Commercial Projects: What Specifiers Need to Know
Architects designers and specifiers have specific requirements when choosing flooring for commercial projects. SPC flooring meets many commercial needs but the specifications differ from residential. This guide covers what commercial specifiers need to know.
Wear Layer Requirements
Commercial projects require thicker wear layers than residential. Light commercial offices need at least 0.5mm wear layer. Retail stores and schools need 0.7mm wear layer. 0.7mm (28mil) is the highest wear layer commonly available and sufficient for the most demanding commercial applications. The wear layer determines how long the floor lasts under commercial traffic. Specify at least 0.3mm for light commercial and 0.5mm for standard commercial applications.
Fire Rating Requirements
Commercial buildings require flooring that meets fire safety standards. SPC flooring typically achieves a Bf1 fire rating (European standard) or Class 2 (ASTM E648). This is suitable for standard commercial applications. For projects requiring A level fire rating, SWF flooring is recommended. Check the specific fire test certification for the product you are specifying. ASTM E648 or NFPA 253 Class 1 is the standard for commercial flooring.
Slip Resistance
Commercial spaces need flooring with adequate slip resistance. The coefficient of friction for SPC flooring varies by surface texture. Textured finishes with embossing provide better slip resistance than smooth finishes. Specify SPC with a dynamic coefficient of friction of 0.42 or higher for commercial applications. This meets ADA recommendations for slip resistance.
Acoustic Performance
Multi story commercial buildings require sound control. IIC Impact Insulation Class ratings measure impact sound transmission. STC Sound Transmission Class ratings measure airborne sound. Specify appropriate underlayment to meet building code requirements. IIC 50 or higher is typically required for multi family and commercial buildings.
Warranty for Commercial Use
Residential warranties do not cover commercial applications. Ensure the product you specify has a commercial warranty. Most quality SPC products offer 5 to 10 year commercial warranties depending on the product line. Verify the warranty terms in writing before specifying the product.
Installation Considerations for Commercial
Commercial installation should be done by experienced professionals. The subfloor requirements are the same as residential at 3mm over 2 meters flatness. Larger commercial spaces require more expansion gaps and T-moldings. Install T-moldings at doorways and every 12 to 15 meters in long corridors. Acoustic underlayment is typically required for commercial installations above ground level.
