An energy-efficient home will require less air conditioning and heating, reducing energy bills. An energy-efficient house is kinder to the environment as well, and it will have more buyer appeal if you should decide to sell it in the future. One of the ways to make your place more efficient is to install double-glazed windows. Here are a couple of tips to consider when undertaking this kind of project.

U-Values and R-Values

When you research double glazing products, ask what their U-values and R-values are. The U-value refers to the rate at which heat transfers through the window. On a hot day, the U-value describes how much heat will enter your house via the windows. A lower value is better than a higher value, as it means that less heat gets inside.

Another rating to think about is a product's R-value. This rating refers to how well the unit resists heat travelling through the window. This rating is more relevant to how well double glazing prevents heat from escaping during winter. With respect to this rating, a higher number is better than a lower number as it offers greater resistance to the warmth leaving your house.

The Gap Between the Panes 

Double-glazed windows consist of two separate glass panes that are set within one frame. The particular setup can vary, making the glazing more or less efficient. A wider gap will make it harder for heat to cross over, making the unit more efficient.

Another crucial factor is what fills the gap between the two glass panes. It could be air, which does provide a block to the heat jumping over. Alternatively, it may be filled with argon gas, which is more efficient than air. Thus, when choosing double glazing, inquire about the width of the gap and how it is filled.

Window Structures

Double glazing can be fitted into various window styles, including sliding, awning or double-hung windows. You can install double-glazed glass doors as well. So, regardless of your home's windows, you are able to make them more efficient.

Double-glazed windows typically have frames made of timber, PVC, or aluminium. Some aluminium windows have a thermal break, which is a middle layer of alternative material, such as PVC. This contrasting material hinders heat from transferring through the metal window frames. Timber and PVC frames do not conduct heat as freely as aluminium ones do without a thermal break.
