In our current world where vehicles are ever-present, we’re able to much more conveniently get to where we want, and quicker at that. Unfortunately, noise pollution is an inevitable byproduct of this convenience. Even taking vehicles out of the equation though, there are still other noise sources. These include construction work, road works, and your neighbors blasting music or even just having a lively gathering. Either way, noise can come from many sources, and everyone wants a quiet oasis in their own home. In today’s world where noise pollution is inevitable, noise-resistant siding is a must, especially if you’re staying near a road. So if you’re wondering which siding materials to use and how to install them to block out noise, jump right in! What Makes Siding Able To Keep Out Sound? While you might be surprised to hear this, the siding material isn’t the most important factor in keeping sound out. Instead, factors like sealing and layering play a much larger role in insulating your home against sound. By knowing the factors that keep sound out, you’ll be better able to liaise with your contractor and perhaps even perform the installation yourself. Density & Mass The denser a material is, the more sound it blocks out, simply because sound has to travel more material to reach your home. Assuming you have two materials of equal thickness, the denser material would block out more sound. However, it isn’t always that simple, as you have to consider the thickness to determine the overall mass. A thicker material with more volume and lower density can have more mass than a denser but thinner material, and thus block out sound better. So it isn’t always the case that a denser material will block out more sound, but it tends to be safer to opt for denser materials, because if you opt for a less dense material instead, you’ll end up having to use a thicker layer to block out the same amount of sound. Tight Construction & Sealing No matter how good your siding is at keeping out sound, if there are gaps, sound will pass through those gaps and still reach your home. As such, during the construction and assembly of the wall, not just the siding, but for each of the layers, the sheathing, the insulation layer, and so on, care needs to be taken to ensure there are no gaps. This means each piece needs to be aligned properly and at points where the layers meet the wall or doors and windows, they need to be installed tightly. There will inevitably be some gaps of course, usually at the seams and at the areas where the layers meet the wall or doors and windows. That’s where sealing comes in. Wherever there are gaps, you need to use the appropriate sealant to seal them up. If they're not sealed up, not only will more sound get through, but your home’s energy efficiency will also decrease, and moisture will also get through, causing issues like mold, mildew, and moisture damage. Layering Lastly, note that your siding isn’t the only thing blocking out sound from your home. Many homes, especially modern ones, incorporate multiple layers, usually starting with the siding on the outside, then a weather-resistant barrier below, then sheathing, and finally an insulating layer for energy efficiency. Each of these layers has its own purpose such as keeping moisture out, serving as a base for additional layers, and insulating your home to enhance energy efficiency. While each of their purposes isn’t to insulate against sound, each additional layer is more material that sound has to travel through, which means less sound reaches your home. So your siding isn’t a lone warrior fighting to keep out sound on its own. It has other layers to help, even if their main purpose isn’t to block sound out.
