Laminate Flooring Experts Key Factors for Buying Laminate Planks Thickness: Choose 10 mm to 12 mm thick planks. Thinner planks (6-8 mm) are cheaper but break easier and feel less stable. AC Rating (Durability) AC3: Suitable for heavy residential traffic (living rooms, hallways). AC4/AC5: Ideal for high-traffic homes, pets, and light commercial use. Water Resistance: Look for "water-resistant" or "waterproof" laminate, specifically for kitchens, bathrooms, and basements. Texture & Style: Embossed-in-register (EIR) textures match the wood grain pattern for a highly realistic look. Installation & Padding: Opt for planks with pre-attached underlayment to save on installation time and reduce noise. Common Mistakes to Avoid Ignoring the need for proper acclimation (letting planks sit in the room for 1-3 days before installing). Skipping underlayment, which results in a loud, hollow-sounding floor. Buying too little; always add 10% for waste and cutting. Top Considerations by Room Living Rooms/Hallways: AC3 or AC4 (High traffic). Kitchens/Basements: Water-resistant/Waterproof core. Bedrooms: A lower AC rating is acceptable, but 10 mm+ provides better comfort.
