Double glazing windows how does it work

While the gas layer between the panes is a good insulator, traditional double glazing still loses heat through conduction. In older windows, aluminium spacers were placed between the panes of glass to seal the unit, but metal spacers actually conduct heat between the two panes. These spacers allow warmth to travel from the inner pane to the outer even if it struggles to get through the layer of air or argon, preventing older double glazing from working effectively.

However, this problem is eliminated by newer double glazing styles that you can buy from innovative manufacturers like KLG Rutland. These improved windows make use of Warm Edge technology, which uses insulating plastic spacers instead of aluminium. Composite plastic spacers form another barrier to any heat that tries to pass through the window, creating a complete layer of insulation between the panes. Sound is created through vibrations, and the energy from a sound wave travels from its source point until it gets to our ears.

Therefore, if another glass pane acts as an extra layer, it will get in the way of the sound wave reducing noise from entering the room.

The larger the gap between the glass panes, the greater the acoustic insulation advantages. Trickle vents fitted to the windows for ventilation purposes can allow unwanted sound to enter the property. To fix this problem, you can try fitting special acoustic ventilators. When the air is warm, the molecules holding the moisture are spaced apart.

As the air cools down, the water molecules get closer to each other. Condensation occurs when moisture-laden air gets in touch with a cold exterior — like a windowpane. When you cook food, boil a kettle, or have a hot shower, the surrounding air gets filled with more moisture than usual, and condensation appears on the bathroom mirrors and kitchen windows.

In the double glazed unit, the air in the gap holds a low amount of moisture that could manifest on the glass surface if the temperature difference changes. Each sealed unit contains a crystalline desiccant inside the spacer bar. Interior condensation occurs when the sealed unit seals start to fail, and more moisture enters the sealed unit. The desiccant gets saturated and cannot hold any more moisture, and as a result, condensation occurs in the unit.

Many double glazed windows are manufactured with PVCu or aluminium frames, which are both durable and efficient materials. There should be no small gaps around the window frames to allow cold air to enter the house. By adding an extra piece of glass to your windows, you can vastly reduce heat loss and reduce the annual cost of your energy bill. Double glazed windows have a heap of other advantages too — for example two panes are much more difficult to smash than one, so they can further increase home security.

They are guaranteed to add value to your home if you upgrade from single pane to double glazed windows, as they will increase the overall energy efficiency of the property.

The second window pane acts as more of a barrier to noise, keeping your home quiet and peaceful. Reduced Energy Costs In turn, you will notice that your energy costs will be decreased significantly as you will start saving a lot more money through double glazing than you did with single glazed windows. Increased Security One of the more obvious benefits is the increased safety and security of your home.

By installing double glazing, the increased security will be enough to deter unwanted intruders. Window Opening Options A commonly asked question we often hear is that do the different window opening options such as casement windows, tilt and turn and french windows, do they make a difference to energy efficiency and privacy? The difference between styles is marginal if not at all. What are window energy ratings?
