It is expected that even after COVID-19 subside, what the working class will find is that working from home (WFH) is still a New Normal, and that work can take place anywhere as long as utilities and facilities are provided as more and more people work via the internet while the need for travel to meet become less. These all reduce the importance of the office and at the same time make WFH more significant.
In addition to being a home office, home is also an area for other activities as people spend more time inside the house. Maintaining a home environment for a wide range of activities, keeping it clean, safe, good for the soul, peaceful, and comfortable, has become important.
In the future, if more and more people work at home, the home environment should be adjusted to reflect good working conditions. Therefore, another important element is to prevent outside noise in order to control the appropriate level of indoor tranquility.
“Noise,” although it may seem like a small matter, may distract us and is a beginning for stress, which affects 10-15% of our productivity and daily life.
According to the previous article on “Soundproof Doors ... At Work”, we have already mentioned the principles of controlling indoor noise: Control of the medium that transfers noise from outside to inside, the partition between outside and inside is critical in reducing the emission of noise from one side to the other.
For the methods of designing for soundproof windows, in general there are seven points to consider:
1. The designed system of Window frames profile bar
2. Joints or Seam of Window frames fabrication
3. Seals between the window frames and panels (or sashs)
4. Hardware of the door/window that will affect in tightness
5. Glass type (if applicable)
6. How to install joints between frames and building walls
7. Window opening size
One of the main elements of a window is glass, which has different sound insulation level depends on quite a few factors: Glass type, Thickness, etc. Also the bigger area of glass in a window, the more significant impact it become. There are 2 types of glass that is considered to help insulate the noise, as follows:
1. Laminated glass: it is two pieces of glass sandwiched together and stick by film such as PVB, making it more secure because if there is a force to hit the glass, it will not be broken into pieces as there is a film to help adhere, which is the same feature as the windshield. A by-product of the film sandwiched between the laminated glass helps absorb low-frequency noise better than conventional glass.
2. Insulated Glass (IG): it is two sheets of glass attached together but left an air gap between the glass. In some cases, it is a normal dry air, or in some case, it’s filled with argon gas to improve the efficiency of heat insulation to pass through the glass more hardly. The air chamber between glass also helps to prevent noise from entering a building.
In addition to the soundproof properties of each type of glass, both perform different advantage (safety or heat insulation) that we may consider according to the feature needed.
Another element of soundproof windows that should be aware of is the opening and closing feature of the windows in relation to the protection of the joints between a frame and a pane. For example, a window that is not suitable for soundproofing is a shuttered window because there are long gap between the shutters. On the contrary, the most effective soundproof windows are casement windows because it is designed to close the window panels more firmly, not like the sliding set that still need to leave some gap when sliding.
Based on the above mentioned soundproof window considerations, Deceuninck has developed uPVC soundproof windows which completely cover the weaknesses that the windows had on soundproofing, such as high quality of UPVC extrusion with distinct chamber designs, quality rubber gasket, complete seaming of profile fabrication.
As for sliding windows, they are generally less soundproof than the casement windows. However, our uPVC soundproof windows also have a Premium-line sliding system with a detailed sliding rail device that can lock the panel tightly to the frame every time when sliding, and the frame can also be equipped with three layers of insulated glass, providing excellent soundproofing.
In addition to insulated glass and window frames, uPVC can also be adjusted to accommodate various glass thicknesses as appropriate for use, such as 10.76 mm thickness laminated glass (5 mm glass + 0.76 mm PVB + 5 mm glass) or 24 mm thick insulated glass (6 mm glass + 12 mm air inlet + 6 mm glass).
As mentioned above, it shows that Deceuninck has developed the uPVC soundproof panes to fix the weaknesses of different types of windows and to be soundproofing, especially suitable for the installation of home openings as in the future, more and more people who may stay at home may need to use durable openings and tools, and PVC windows will definitely meet that need.
