Laminate floors are separated by four grade international standards to rate their durability (AC1, AC2, AC3 & AC4). At DECNO Floor, all of our products feature the ACR click system which allows for easy assembly, without the hassle of fidgeting with glue. They have a grade of AC3 or above – surface is scratch resistant and can withstand heat of up to 60 degrees Celsius. The clip system featured in this product is user friendly and can be easily assembled. The result is just as strong and stable as the traditional glued laminate floor .
