Through Old Windows and Doors, 40% of Energy is Lost During Winter!

in #window15 days ago

Windows and doors are essential elements of any home. They provide security, privacy, protect the interior of the house from external factors, and contribute to the aesthetics of the facade and the space in general. They also play a significant role in the thermal insulation of the building. Did you know that up to 40% of heating energy is lost through old, worn-out windows and doors during winter? This will be reflected in your monthly bills. Therefore, we asked experts how to recognize when it’s time to replace your windows and doors and when energy starts escaping through them.

The platform Daibau.rs ( https://www.daibau.rs/ ), which has 1,768 registered companies in Serbia for the sale and installation of windows, 978 companies for entrance doors, and 1,131 companies for interior doors, consulted with its registered businesses to determine when it’s necessary to replace your windows and doors in order to prevent heat loss and higher energy consumption this winter. Some signs are visible, while others may not be so obvious.

Condensation is a clear indicator
Condensation is easy to spot: foggy windows and balcony doors during winter. It occurs when warm, moist air (more common in winter due to less frequent ventilation) comes into contact with a cold glass surface. At that point, the air temperature starts to drop rapidly, along with its ability to hold moisture. The result is foggy glass and water droplets sliding down the window.

Cold surfaces form due to poorly sealed joints of windows and doors, and/or when the frames are worn out. In such cases, thermal bridges also appear. If you notice constant condensation in your home, it's a clear sign that it’s time to contact professionals who can expertly replace your windows and doors.

Windows and doors leak during rain
This is a clear sign that replacement is necessary, especially if heavy rainfall is expected in the coming period. If water has found its way into your home, it means your windows and doors are not functioning properly. It’s time to replace the old windows and doors with new ones.

When it comes to windows, more and more people are opting for PVC ones. PVC windows offer an excellent balance between price and quality, providing good sound and thermal insulation. However, when purchasing PVC windows, it’s important to pay attention to the number of chambers – the more chambers they have, the better the insulation. Those with six chambers are a good choice. Also, for PVC windows to be energy-efficient and last for decades, proper installation is essential.

All reviews of contractors and previous customers' experiences are transparent, and you can also find approximate prices to better plan your budget.

Mold appearance
Persistent black spots at the joints of the windows and walls indicate that your windows are allowing cold air to pass through. Mold not only ruins the aesthetics of the room but is also harmful to human health, especially for those with respiratory problems. Additionally, it creates an unpleasant smell that spreads throughout the room. When you notice mold, call professionals to first determine whether a repair is possible. If not, it’s time to replace your windows and doors.

You feel cold air leaking near the windows and doors
If the windows and doors aren’t properly sealed, staying in the rooms will be far from comfortable during winter. No matter how much you increase the heating, if cold air is entering through thermal bridges, it won’t be warm enough. The situation isn’t any better during the summer – you’ll feel hot air entering the room even though the air conditioner is on. This increases the cost of climate control. The problem can be solved by sealing, but in the long run, it’s recommended to replace the windows and doors.
"The feeling of a draft, even when the windows and doors are closed, is a clear sign that energy is being lost from the building," said a registered window and door installer with many years of experience.

This problem doesn’t only occur with windows but also with doors. Entrance doors, in addition to providing security and aesthetics, must also offer thermal insulation. To fulfill their multiple roles, they need to be made of strong materials and properly installed. For purchasing and installing entrance doors, choose reputable companies that offer long-term guarantees.

The windows and doors are difficult to open/close
This is one of the most common problems with windows and doors after years of use. Often, the difficulty in opening windows and doors can be resolved with a simple repair, but it’s a clear indication that the life span of the windows and doors is nearing its end and they should be replaced in the near future. If every time you open a window or door it causes discomfort and requires physical effort, it means their functionality has deteriorated.

Unbearable noise
Lastly, if you hear street noise as if you're outside, it's another sign that you probably need new windows. An interesting fact is that windows let in 7 times more noise than walls. If the windows are damaged, they will no longer provide good sound insulation.

Also, if you can hear noise from another room louder and clearer than usual, it might be time to replace your interior doors
Although it represents a significant investment, replacing windows and doors will contribute to safety, comfort, and improve the aesthetics of your home.
