Single-pane windows are still manufactured and legal in California
Single-pane windows are still manufactured and sold in California, but they are not commonly used anymore due to their drawbacks. Single-pane windows were once the standard in homes, but they offer poor insulation compared to modern double- and triple-pane windows. They allow heat to easily transfer in and out, leading to increased energy costs. Additionally, they do not block outside noise as effectively as multi-pane windows, which have insulating air spaces that reduce noise infiltration.
Despite their disadvantages, single-pane windows are still favoured by some due to their simplicity and affordability. They are less expensive and simpler to install than double- or triple-pane windows. For these reasons, they are often found in older homes and buildings.
In California, all residential homes must comply with Title 24 energy standards, which aim to improve energy efficiency and reduce environmental impact. While Title 24 regulations do apply to the installation of new windows, it is unclear whether they specifically prohibit the use of single-pane windows. However, to comply with these standards, most fenestration manufacturers have adopted U-Factors and SHGCs for their product lines, which often involve the use of thicker double panes and low E glass.
Therefore, while single-pane windows may still be manufactured and sold in California, they are likely becoming less common due to the state's focus on energy efficiency and the superior performance of multi-pane windows in this regard. Nonetheless, it is essential for homeowners to make informed decisions by considering the advantages and disadvantages of each type of window.

They are less energy-efficient than double or triple-pane windows
Single-pane windows are less energy-efficient than double or triple-pane windows due to their poor insulating properties. With only one layer of glass, single-pane windows allow heat to transfer through the window more easily. During winter, warm air from inside the house can quickly escape, and cold outdoor air can seep in. Conversely, in the summer, the outside heat enters the house, and the cool indoor air escapes. This results in higher energy costs as the HVAC system has to work harder to maintain a comfortable temperature, increasing energy consumption and utility bills.
On the other hand, double or triple-pane windows feature two or three layers of glass with an insulating layer of air or gas in between. This design significantly reduces heat transfer, providing better insulation and energy efficiency. The additional layers act as a barrier, preventing heat from escaping in the winter and outside heat from entering in the summer, thus keeping your home cooler in the summer and warmer in the winter.
The improved insulation of double and triple-pane windows also helps to reduce condensation. Condensation forms when warm air comes into contact with a cold surface. In single-pane windows, the glass can get cold enough to cause moisture to condense inside the window. However, with double or triple-pane windows, the inner pane is kept at a warmer temperature, reducing the likelihood of condensation forming and preventing moisture damage to window frames, walls, and floors.
Additionally, single-pane windows offer limited noise reduction compared to their multi-pane counterparts. The lack of an insulating air space between panes allows sound waves to travel through the window more efficiently, leading to increased outside noise infiltration. Upgrading to double or triple-pane windows can significantly reduce outside noise, providing a quieter indoor environment, especially in urban areas or busy neighbourhoods.
While single-pane windows may be more affordable and simple to install, their lack of energy efficiency can lead to higher long-term costs and a less comfortable living environment. Upgrading to double or triple-pane windows can provide significant energy savings, improved insulation, reduced condensation, and a quieter home.

They are poor insulators, allowing heat to escape in winter and enter in summer
Single-pane windows are poor insulators, allowing heat to escape during winter and enter during summer. This is due to their lack of an insulating layer, which means that there is nothing to prevent heat from moving through the window. As a result, the indoor temperature is more susceptible to changes in outdoor temperature, leading to increased energy costs for heating and cooling.
In contrast, modern double- or triple-pane windows have two or three layers of glass with an insulating layer of air or gas between them. This design creates a barrier that significantly reduces heat transfer, keeping your home warmer in winter and cooler in summer. For example, during winter, the insulating layer prevents warm air from escaping and cold air from entering, while in summer, it helps to keep hot outdoor air out and cool indoor air in.
The improved insulation provided by double- or triple-pane windows leads to several benefits. Firstly, it increases energy efficiency, resulting in lower energy bills. Secondly, it reduces condensation, which can cause moisture damage to window frames, walls, and floors. Thirdly, it helps to maintain a more consistent indoor temperature, improving comfort.
While single-pane windows may still be manufactured and installed in certain locations, they are not as commonly used as modern alternatives due to their poor insulating properties. Upgrading to double- or triple-pane windows can provide significant advantages in terms of energy savings, comfort, and condensation reduction. However, single-pane windows may still be a viable option for outbuildings or structures where thermal efficiency is not a primary concern, thanks to their simplicity, affordability, and ease of installation.

They are more prone to condensation and moisture damage
Single-pane windows are more susceptible to condensation and moisture damage. Condensation occurs when warm air comes into contact with a cold surface. In single-pane windows, the interior glass can get cold enough to cause moisture to condense inside the window. This condensation can lead to water damage, mould growth, rotting frames, and even structural damage.
The lack of insulation in single-pane windows is a significant factor contributing to this issue. Without an insulating layer of air or gas between multiple panes, single-pane windows allow for more efficient heat transfer. As a result, the indoor temperature can drop, causing the interior glass to reach a low enough temperature to cause condensation.
In contrast, double or triple-pane windows provide improved insulation. The insulating air or gas-filled space between the panes helps maintain a warmer temperature on the inner pane, reducing the likelihood of condensation. This design not only prevents moisture damage but also enhances energy efficiency by reducing heating and cooling costs.
While single-pane windows may still be manufactured and offer advantages such as simplicity and affordability, their poor insulation makes them more prone to condensation and the associated moisture damage. Therefore, it is advisable to consider upgrading to multiple-pane windows to mitigate these issues and create a more comfortable and energy-efficient living environment.
