How do you determine the finished floor level? And what's the difference between a finished floor and a screed? This is a question that can be confusing even for some DIYers, not to mention do-it-yourselfers. First of all, it's important to understand that there are no one-size-fits-all solutions, and the devil is in the details. But there are certain guidelines that must be considered together to make a final decision. ☝️As a rule, the finished floor level determines the level behind the front door, where common areas are located. Why is this important? It's simple: you, your family, and your guests shouldn't experience discomfort or tripping when entering or exiting the apartment. If the floor level in the stairwell and in the apartment is different, you might twist an ankle or simply use more swear words. 📝Next, you need to determine the planned floor structure, taking into account the design loads. 📐First, you need to determine whether your home has a screed. For example, there are panel houses where the floor slab is almost flush with the hallway floor, leaving only a small amount of height for leveling with a polymer "self-leveling floor" mixture and the final coating. And there are monolithic houses where 10-12 cm is laid for screed. ✏️And we need to consider the complex pie of floor layers. First, according to SP 51.13330.2011 "Noise Protection," a soundproofing layer is required, such as Shumoizol Pro from Maxforte – 5 mm. Some do, some don't. 🎓Next, read SP 29.13330.2011 "Floors," section 8 "Screed (base under the floor covering)." According to clause 8.2, the minimum thickness of a cement-sand or concrete screed, including for creating a slope at the junction with gutters, channels, and drains, when laid on floor slabs should be 20 mm. If the screed is laid over a heat- and sound-insulating layer, the minimum thickness should be 40 mm. The thickness of the screed used to cover pipes (including in heated floors) should be at least 45 mm greater than the diameter of the pipes. Above the screed is a sublayer—an intermediate floor layer that bonds the flooring to the underlying floor layer. Specifically, this sublayer includes cement-based adhesive for tiles and porcelain tiles (2-3 mm), synthetic resin-based sublayers used for tiles and porcelain tiles (2-4 mm), no more than 1 mm for parquet and laminate flooring, and no more than 0.8 mm for linoleum. Finally, you need to consider the height of the finished flooring. Ceramic tiles and porcelain tiles: 6-12 mm; quartz vinyl: 2-5 mm; laminate: 7-12 mm (the most common is 8 mm) and 2-3 mm underlayment; parquet board: 12-15 mm; engineered wood flooring: 12-21 mm. #finishedfloor #screedlevel #engineeringnotebook ХХХХХХХХХХХХХХХХХХХХХХХХХХХХХХХХХХХХХХХХХХХХХХХХХХХХХХХХХХХХХХХХХХХХХХХ More information about us on our website https://engineering-profile.ru https://www.t.me/engineering_profile_...
