The windows are critical elements in the functional and aesthetic performance of a residential building. Therefore, it is essential to select the right window products when building a new home or carrying out renovations. One of the advantageous treatments to consider purchasing and installing is the double-glazed window. This is an insulated glass product that combines two glass panes into a single unit. The double glazing is designed to reduce transfer of heat across the window spaces. This will improve thermal insulation and consequently, energy efficiency. In addition, the treatment can advance acoustic insulation and even home security. Here are the performance factors that you must evaluate when selecting residential double-glazed windows.

Glass Type

There are different glass products in the market that are used in fabrication of windows. Your selection for residential applications will affect the long-term performance of the treatment. Low emissivity glass is a common glazing material for double-glazed window panes. This is a glass sheet product that has a transparent but metallic layer designed to enhance energy efficiency. The coating will reduce loss of heat from your interior space through reflection. It will still allow natural light to filter into your home. Laminated glass panes are also popular because they improve acoustic performance of the windows. These are thicker, so they will absorb external noise more efficiently. In addition, this type of glass is harder to break, enhancing your home security.

Construction

You should assess the design and construction of the windows before making your purchase. Generally, double-glazed windows are built as two parallel glass panes with a space in-between. You should inquire about the amount of the space because it will affect the insulating properties of your window. Larger gaps are ideal for optimal thermal and acoustic performance of your home. You should also note that gases with low conductivity can be filled into the gap to enhance these properties. One of the popular choices is argon because it will limit heat loss and gain. Moreover, it is critical to make certain that the spacers between the glass panes have desiccant. This material will remove the water vapour within the spacers, preventing fogging.

Framing

Finally, you should choose framing that will enhance the performance of the double glazing. Ideal frame materials should limit the absorption and emission of heat across their structures. For instance, aluminium is relatively popular, but its conductivity will compromise the insulation value of the glazing. Instead of this, consider purchasing frames made from wood, composites and uPVC since the materials are good thermal insulators.
