While we offer a range of high-quality products for residential use, we believe in transparency and ensuring that our customers make informed decisions. We’ve been asked a few times if your film can be installed on triple pane windows. The short answer is no, and in this blog post, we’ll discuss the reasons why you should avoid installing window film on triple-pane glass.
Triple pane windows have gained popularity for their superior energy efficiency. A triple pane window, also known as a triple glazing or triple glazed window, is a type of window that consists of three layers of glass separated by two insulating spaces. These windows are designed to provide enhanced insulation and energy efficiency compared to traditional single or double pane windows.
Here’s a breakdown of the key components of a triple glazed window:
Unlike single pane windows, which consist of a single sheet of glass, and double pane windows, which have two layers of glass, triple pane windows feature three layers of glass. These multiple layers create additional barriers to heat transfer.
Between each layer of glass, there are two insulating spaces. These spaces are typically filled with an insulating gas, such as argon or krypton, to further reduce heat transfer. The gas acts as a thermal barrier, preventing the transfer of heat between the interior and exterior of the building.
The primary advantage of triple glazed windows is their superior energy efficiency. They provide better insulation, which helps maintain a stable indoor temperature and reduces the need for heating or cooling. This can result in lower energy bills and improved comfort in the home.
In addition to energy efficiency, triple glazing also offer improved sound insulation. The multiple layers of glass and insulating spaces help reduce external noise, creating a quieter and more peaceful indoor environment.
Triple pane windows often come with coatings that block a significant amount of harmful ultraviolet (UV) radiation. This helps protect furnishings, flooring, and other interior items from fading or damage caused by UV exposure.
With that structure and level of energy efficiency – and added cost (triple pane windows cost 167% more than double pane windows according to Architectural Digest), it’s important to know that our window film is not a fit for triple pane windows. Let’s dig into the why:
Triple pane windows are designed to perform optimally without additional coatings. Adding window film can create thermal stress. When the film absorbs and holds heat, it can lead to uneven expansion and contraction of the glass, which may result in cracks or even shattered panes. This not only compromises the integrity of the window but can also negate the energy-saving benefits of triple glazing.
Most window manufacturers provide warranties that cover the performance and integrity of their products. Installing window film on triple glazed glass can often void these warranties. In the event of any issues or damage to the windows, you may find yourself responsible for costly repairs or replacements.
Triple pane windows are already designed to provide exceptional insulation and UV protection. Adding window film may offer minimal additional benefits in terms of energy efficiency or UV protection, making it an unnecessary expense.
While ComforTech Ceramic Series window film can be a valuable addition to many types of windows – including double pane windows, it’s important to recognize that triple pane windows are a special case. Their construction and design prioritize energy efficiency, and adding window film can potentially negate these benefits, leading to unintended consequences.
