Reducing the effect of greenhouse gases is a difficult task. Innovative technologies play a key role here. Many windows manufacturers in the US and Canada are switching to energy-efficient products. It helps with reduction of energy costs.

What Are Passive House Windows?

Passive house windows are highly energy efficient windows, optimized for the passive house. There are two main types of passive house windows. First for a cooling passive house and for a heating passive house. Windows for a mostly heating passive house have a higher solar coefficient (solar heat gain coefficient). For mostly cooling passive houses, the main target is to prevent overheating from the sun. They usually have lower solar coefficient. It can be up to 3 times lowers than in the first group.

Passive house windows should minimize energy loss and offer low u-value. We provide products that incorporate German Gealan S9000 windows system. It is one of the best high performing PVC profiles.

Are passive houses worth it?

All depends on how well the passive house is optimized. Better to pay slightly more for the energy and less for the mortgage. Or the energy saving is your number one priority. Passive homes are like a diesel car. They save fuel (energy) but not money. A passive house could consider as an investment project. Any energy saving improvements may have a positive return on investment. Also, a passive house project should be stable in the long term. Without a tendency to rot, mold, and other moisture related damage. We help our customers find balanced solution, to avoid inconsistencies.

What is a passive window?

Passive house windows have high energy efficiency. The glass unit should have an R value of 8-11 or more. The frame should also be better than R5 – R6. Depends on the target, a passive window may have a high solar coefficient. For cold climate passive homes, high solar coefficient is desired. For warm climate passive homes, low solar coefficient is optimal. Depending on the climate and location on the project. It is important to choose the right type of passive window, type of insulation, and a proper wall and roof system.

How does passive house work?

The conception of a passive house is the next generation of the net zero concept. The passive house is based on very low energy consumption. Built with super insulation and a high focus on solar energy utilization. Close to zero energy consumption form outside sources. Up to 15kilo watt hours per square meter of the house per year (1.6 kilo watt hours per square feet, per year). Roughly $50 -$200 energy bill for a 1000 sq.ft, per year, depends on the energy source.

Passive houses are buildings that adhere to specific energy standards. They aim to reduce carbon footprint. They are ultra-low energy buildings. Passive houses optimize heating/cooling device usage. With passive house windows, homeowners can preserve heat. They can maintain a set temperature for a longer period. However, one should avoid substandard thermal insulators. They add no value to a home but increase the cost of construction. It is important to check windows’ info for heat loss/gain.

It will be more affordable for a passive house in the future. There are more and more companies that offer products for such projects. There is an increase in amount of resources that can help people. Many have transformed a regular house into a passive house. Attention to detail is required to find materials for such project.

Building Standards for Passive House

To be certified, a building is required to meet specific criteria. This is a set of guidelines that may vary depending on the region. Some major principles to be followed are listed below:

• Solar Power

Passive house design maximizes the use of sunlight. It uses natural energy to heat the building. The project needs to put specific systems in place to prevent overheating. Specialists in the field can help with that. Using materials that achieve a zero net energy are a necessity. Choosing the right type of windows is essential.

• Superior insulation

High quality of insulation is vital. It keeps the heat inside during winter months. It also must keep the house at a cool temperature in the summer. Passive House Institute provides a lot of information. It describes how high level of insulation can be achieved. We suggest how it can be done in a more cost-efficient but effective way.

• Glazing and Solar Heat Gain Control

Passive house windows help to optimize solar energy consumption. People prefer to install fixed and tilt turn windows in passive houses. They have great insulation properties. Companies offer quadruple glazed windows made with special glazing glass. They help to achieve an even more impressive results.

We offer quadruple pane windows as well. We assess each specific case to find a perfect window glazing. Choosing right materials is important for the passive house project.

We offer different types of glazing for windows. This type would depend on what cardinal direction window faces. It allows us to take advantage of the physical properties of products. It is an important to optimize SHGC with especially for south windows. Such solution would prevent overheating in certain rooms. But it would allow natural sunlight inside at the same time.

We provide two low-e glasses in triple pane windows. The level of visible light losses of 26% is very low. It is closed to cold double pane windows with one low-e glass. We have increased thermal insulation of our products. We compare them here to regular triple pane windows with one low-e glass.

What Is The U-value?

The U-value is a thermal conductivity measurement of any material. It can also be called heat transfer rate. It’s a formula that divides the rate of heat transfer by the temperature difference of structures. So, a high U-value means an increase in heat loss. U-value of a building is the reciprocal of the sum of its respective materials.

What Is the R-value?

R-value is an accurate method of measuring thermal insulation. Normally, it’s calculated as the reciprocal of the U-value. If one knows the thermal conductivity of any material, divide the value by its thickness level. The result is in (m²K/W) is the R-value.

R-values show a material’s strength of resisting heat flow. It is different from thermal transmittance. The material could be a high-quality thermal glass window. Low U-Value is good. R-values should be higher for building materials. That would indicate their better insulating properties. Higher the number, higher the thermal resistance of a product. It is important to use and install the right insulation materials.

We outperform many companies when it comes to R-value of glass units. Regular triple pane glass units with one low-e glass have an R-value of 5-5.5, depending on the quality of low-e glass. Double pane windows have R-value of 3.7-4. Our regular options incorporate tow low-e glasses. We are able to achieve R-value of 8-8.5.

For high-end projects, can provide triple glass units with R-value 9-10. We have quadruple pane units with R-value of 10-12. The later options can be used in passive house projects. It achieves a higher energy efficiency and thermal insulation.

Glass and Frames

Passive house buildings in many countries use triple glazed windows and uPVC frames. Thermal conductivity of insulating materials depends on several factors. One of them is their physical properties. Architectural design of the final products plays a role as well. Many homeowners live in a climate with harsh weather conditions. They install high-performing triple glazed windows with outstanding insulation.

Companies use modern technology to create energy-efficient windows. Inert gases like Krypton or Argon fill the sealed spaces between the panes. They cover these glass surfaces with low emission (low-e) coating.

What Are the Benefits of Installing Passive House Windows?

Improves Visible Transmittance and Minimizes Heat Losses. Installers should to detail check to get the passive house certified. Efficient windows allow residents to enjoy more balanced temperature. They keep owners’ energy bills at a lower level. Optimized windows allow a lot of natural sunlight into the rooms. This reduces the need for electric lighting in the day time.

Inside a passive house, the temperature should fall below 17 degrees C. Sometimes, the space between windows and walls creates an escape route for heat. Installers should insulate the walls against heat losses. Passive house windows aim to preserve solar gain. Then they use that energy to get a healthy climate inside.

2. Healthy Living.

It is important to have fresh air in living spaces. When there’s condensation, regular windows produce molds on the walls. Passive house windows create a more eco-friendly environment. Generally, passive house certificate standards require airtight tests. The blower door tests help to show the quality of sliding doors.

These tests help door companies to use materials that boost comfort level. Many people can develop or exasperate asthma from damp walls. Thermal bridge free construction in passive homes ensures proper ventilation.

3. Eco-friendly Buildings.

Greenhouse gas emission is a threat to our environment. There is a global trend towards reducing it. Homeowners can contribute by switching to renewable energy. One of the most popular one is solar energy.

There are many advantages of passive house projects. They include lower energy consumption and more sustainable design.


World leaders try to coop with climate change effects. They encourage sustainable construction practices. There are ways to make it easier to achieve set goals. We hope to see more buildings with passive house windows. Triple, quadruple glazed windows increase energy efficiency of a home. They reduce its energy consumption. Energy generation results in production of carbon dioxide. It is the case when we are talking about non-renewable resources. It contributes to the green house effect. Building passive houses is a great way to have a positive effect on the environment. There attention is focused on renewable energy resources. Solar heat gain is an important for the heating and cooling costs. Reflection of solar heat can keep the place cool for a longer time.

Installing passive house windows in a home will increase its energy performance. It would contribute to reducing the amount of consumed energy. It would help the environment and also lower utility bills.

We offer steel reinforced window frames to ensure structural strength of the products. Wide 3-5/16″ (83 mm) window frames help to increase thermal insulation. Windows are important passive house component. It is wise for building owners to do a thorough research on the topic. There are many companies with different product lines. It is especially important for passive house commercial projects. There could be additional for them. There are many designers who specialize in passive house project. They can provide relevant information on the given topic.
