Features of Passive Windows and Doors
Thermally broken: This refers to a specific manufacturing technique wherein the window frame (most often constructed from aluminum) contains a barrier between the inside and outside frames. This energy efficiency technique helps to limit the conductive thermal energy loss from the window.
Extremely Airtight: Windows and their frames also contribute to unwanted heat loss and heat gain via gaps and fissures that lead to drafts. Passive house windows will have a strong focus on airtightness as a tight building envelope is a core principle of the passive house standard.
Triple Glazed Windows: Passive house windows will also opt for the most energy-efficient window technology available. In today's market, triple-glazed windows with the gaps between the individual glass panes filled with argon or krypton gas are widely thought to be the most efficient option.
Low-E Glass: Low-emissivity (low-E) glass is the industry standard. This type of glass has a thin coating of metal oxide on one internal glass surface. The metal oxide coating improves the window's thermal performance by reflecting heat into the home while not affecting the incoming external light. Windows with low-E glass allow homeowners to enjoy the warmth and light of the sun in the winter without losing interior heat.
U-Value and R-Value Measurements: A window's energy efficiency is measured by its U-Value and R-value. A U-value is a precise calculation of the conduction properties of the different elements that make up the window. The U-Value of a window will measure the insulating ability of the window and act as an indicator of heat transfer. The R-value of a window, in contrast, measures the amount of heat retained by the window. Passive house windows will have a low U-value and high R-value. They will also be designed to maximize solar gain and minimize heat loss.
What are Passive House windows made from?
Passive House Window Glazing
Passive House glazing must be energy efficient. This typically means either triple glazing or quad glazing. However, both of these options typically require big chunky window frames and a very modern aesthetic – these units also contain Noble gases which are highly energy intensive to isolate and the performance of the units reduce significantly in service. The new option on the market, which gives a much better balance is vacuum glazing – this can use smaller frames, it’s a more sustainable building product and it performs better and for longer.
Triple glazing is obviously 3 panes of energy efficient glass separated by cavities filled with either Argon or Krypton gas.
Vacuum glazing is much lighter than triple glazing (less panes) and has a much narrower profile. The width of the unit (not the frame) is 8.3mm. Triple glazing on the other hand is 38mm – 48mm. Vacuum glazing is also more efficient that triple glazing with a U value of 0.44 – 0.48 compared with 0.7 – 1.0 in Triple glazing.

Scenarios of passive house windows
There are various application scenarios for passive house windows, including
Residential Homes
Passive house windows are ideal for residential homes. These windows help to create a comfortable living space for people. They also reduce energy costs, which are beneficial to homeowners. These windows are designed to keep homes warm during winter and cool during summer. Therefore, they minimize the need for air conditioning and heating systems.
Commercial Buildings
Passive house windows are also important for commercial buildings. They provide a conducive working environment for employees. This is due to their good natural lighting and ventilation. Moreover, these windows help to improve the energy efficiency of commercial buildings. This leads to reduced operational costs and increased profitability for businesses.
Educational Institutions
Educational institutions such as schools and universities benefit from passive house windows. These windows create a comfortable and healthy environment for students and staff. This is important for effective learning and teaching. Additionally, passive house windows improve the energy efficiency of educational institutions. This leads to reduced operational costs, which can be channeled into other educational resources.
Healthcare Facilities
Healthcare facilities require a conducive and healthy environment for patients and staff. Passive house windows provide this environment. This is due to their excellent natural lighting and ventilation. Additionally, passive house windows ensure the energy efficiency of healthcare facilities. This leads to reduced operational costs, which can be used to improve patient care and services.
Hospitality Industry
Passive house windows are popular in the hospitality industry. For instance, hotels, restaurants, and resorts. These windows create a comfortable and healthy environment for guests and staff. They provide good natural lighting and ventilation. Additionally, passive house windows improve the energy efficiency of hospitality facilities. This leads to reduced operational costs and improved profitability for businesses.
