If your phone is not dustproof, it may be more susceptible to damage from dust and debris getting into the internal components. Dust can accumulate inside the phone and potentially cause issues with the buttons, ports, and other hardware. Over time, this can lead to malfunctions and reduced performance. It's important to keep a non-dustproof phone in a protective case and regularly clean the ports and openings to minimize the risk of damage from dust. **

Insulation should be done before plastering. Insulation helps to regulate the temperature inside a building and reduce energy costs, so it is important to install it before the walls are plastered. Plastering over insulation helps to create a smooth and even surface for the walls, ensuring that the insulation is properly covered and protected. Additionally, installing insulation before plastering can help to prevent any potential damage to the insulation material during the plastering process. **

It is not uncommon for dust to accumulate in the speakers of an iPhone 7, as small particles can easily enter through the speaker grills. While the iPhone 7 is not marketed as being completely dustproof, it does have some level of dust and water resistance with an IP67 rating. However, over time, dust can still find its way into the device through various openings. Regularly cleaning the speaker grills with a soft brush or compressed air can help prevent excessive dust buildup and maintain optimal audio quality. **

Sound insulation in new construction apartments can be improved by using high-quality building materials that have soundproofing properties, such as double or triple-pane windows, acoustic insulation in walls and floors, and solid core doors. Additionally, incorporating sound-absorbing materials like carpets, curtains, and acoustic panels can help reduce noise transmission within the apartment. Proper sealing of gaps and cracks in the building envelope can also prevent sound from entering or escaping the apartment. Finally, thoughtful layout and design considerations, such as avoiding shared walls between noisy areas and quiet areas, can further enhance sound insulation in new construction apartments. **

The construction film is typically attached under the floor insulation by laying it directly on the ground or subfloor before the insulation is installed. The film is then secured in place using adhesive tape or staples to ensure it remains in position. This helps to create a vapor barrier and prevent moisture from seeping through the insulation and into the building. Additionally, the construction film helps to improve the overall energy efficiency of the building by reducing heat loss and preventing drafts. **

Sound insulation in new construction apartments can be improved by using high-quality building materials that are specifically designed to reduce noise transmission, such as double or triple-pane windows, soundproofing drywall, and acoustic insulation. Additionally, sealing any gaps or cracks in walls, floors, and ceilings can help prevent sound from traveling between units. Installing sound-absorbing materials like carpets, rugs, and curtains can also help reduce noise levels within the apartment. Finally, incorporating soundproofing techniques during the design phase, such as staggered stud walls or resilient channels, can further enhance sound insulation in new construction apartments. **

Using drywall is generally cheaper for the interior finishing of a solid house compared to plastering the interior walls. Drywall is less labor-intensive and requires fewer materials, making it a more cost-effective option. Additionally, drywall installation is typically faster, which can also result in lower labor costs. Overall, drywall tends to be the more economical choice for interior finishing in a solid house. **

Plastering can be considered difficult for those who are inexperienced or unfamiliar with the process. It requires skill, precision, and attention to detail to achieve a smooth and even finish. Proper preparation, technique, and timing are crucial in achieving a professional result. With practice and patience, plastering can become easier and more manageable. **
