Passive house windows: key elements for efficient construction

Passive house windows: key elements for efficient construction

Passive windows

Passive windows

As environmental awareness and the drive to save energy grows, passive construction is becoming increasingly popular. One of the key elements of Passive House design is properly selected windows. Why are they so important, how do they affect the energy efficiency of a building and what to look for when choosing windows for a Passive House? Answers to these questions can be found in the article below.

Why are passive houses so energy efficient?

Passive houses are designed to minimise heat loss and maximise heat gain. The main goal is to create a building that is self-sufficient in terms of heat, meaning that it does not need a traditional heating system. In order to achieve this, it is necessary to use advanced technologies and materials with a very high thermal insulation factor. This is where windows come in.

The role of windows in passive buildings

Windows in passive houses play several key roles:

  1. Thermal insulation: Windows need to be highly insulated to minimise heat loss in winter and overheating in summer. Windows in passive buildings usually have triple or even quadruple glazing to increase thermal insulation.
  2. Heat permeability: Passive windows must reduce heat transmission. The U-value (meaning the heat transfer coefficient) of windows should be as low as possible.
  3. Heat gains: Windows must be designed to maximise solar heat gain. The g-value (indicating the solar heat gain coefficient) of windows is a key factor.

Passive profile Kömmerling 88 MD

It is worth noting the modern 7-chamber profile with an installation depth of 88 mm - Kömmerling 88 MD, which is a new generation window system. This profile exceeds standards in thermal insulation and introduces new design trends. Thanks to innovative technology, this window system combines complete individuality, outstanding quality and security. The Kömmerling 88 MD is undoubtedly the best 7-chamber window in its class, providing energy efficiency and an installation depth of 88 mm.

The 88 MD window system is a 7-chamber system with a centre seal, characterised by excellent thermal insulation and perfectly matched steel reinforcement. The new generation of profiles in the standard solution meets the requirements for passive houses, providing excellent thermal insulation. With a wide range of colours and the possibility of fitting special fittings, these 7-chamber windows are exactly what you need in a passive building.

How to choose the right windows for a passive house?

  1. Air permeability: Ensure that windows are airtight and do not allow uncontrolled air leakage.
  2. Appropriate design: Choose windows that match the aesthetics and architecture of the building.
  3. Ug-value: Check that the ug-value of the windows is at a high enough level to ensure maximum thermal gains.
  4. Frame and profile type: Consider whether timber, aluminium or plastic framed windows are a better option, taking into account their insulating properties and durability.
  5. Suitable glass surfaces: Choose glass with solar control and anti-reflective properties that can help control the impact of the sun's rays at different times of the day.
  6. Window functionality: Consider whether you want your windows to be movable, side-opening or top-opening. The choice depends on your preferences and comfort.
  7. Opening and closing speed: Passive windows should be easy to operate and allow the air flow in the building to be regulated.
  8. Supplier and manufacturer selection: Make sure you choose a reputable supplier and window manufacturer who offer high quality and meet energy efficiency standards.



Windows play a key role in the design of passive houses, influencing both energy efficiency and occupant comfort. Choosing the right windows that are well-insulated, airtight and efficient in terms of thermal gain is crucial. Passive houses are the future of construction, and properly selected windows are a key step towards energy savings and sustainable living.

Winter and windows

Winter and windows

Winter is a time when taking care of the thermal insulation in our homes becomes crucial. One of the main factors affecting thermal comfort and heating costs is the windows. It is useful to understand what problems can occur during the winter and how to effectively prevent thermal bridges and heat loss through windows.

1. Thermal bridges: What are they?

Thermal bridges are areas in the construction of a building where the thermal insulation is interrupted or reduced. As a result, these areas become 'bridges' for heat loss, resulting in higher heating energy consumption. In the context of windows, thermal bridges can occur around window frames and where the frame connects to the wall structure.

2. double or triple glazed windows: Choice of solution

In winter, double or triple glazed windows provide an excellent thermal barrier compared to single glazed windows. These additional layers of glass create thermal insulation, reducing the risk of thermal bridges and heat loss.

3. adequate insulation around windows

It is important to ensure that windows are properly insulated. Sealing window frames and joints around windows can effectively minimise thermal bridging. It is also worth investing in high quality gaskets and flexible insulation materials.

4. Blinds or facade blinds

Roller shutters or façade blinds are another effective way to protect against heat loss during the winter. They can serve as an additional layer of thermal insulation, reducing thermal bridges around windows. Roller shutters with anti-intrusion or thermal insulation technology are particularly effective.

5. modern window technologies

Today's windows are available with advanced thermal insulation technologies. Thermally caged, triple-glazed windows with a low U-value and modern seals can significantly reduce heat loss and effectively protect against thermal bridges. If you are looking for energy-efficient windows that additionally provide adequate thermal and acoustic insulation, as well as protect you from thermal bridges, our new profile is ideal. Kommerling 88 MDwhich has 7 thermal chambers, an installation depth of 88 mm and 3 welded seals so you can enjoy the warmth in your home.

6 Monitoring of energy consumption

For more advanced solutions, it is worth considering home energy monitoring systems. These can help identify the areas of greatest heat loss so that appropriate corrective action can be taken.

The winter season requires special attention to the thermal insulation in our homes. Taking care to eliminate thermal bridges and heat loss through windows has a significant impact on occupant comfort and heating bills. By choosing the right windows and taking thermal insulation measures, you can enjoy warmth and savings during the winter.

7 Application warm frame

If you want to make sure you don't have to worry about thermal bridges, use a warm frame. Read more about this solution read here. 

Plastic frames, such as PVC, are much more effective in preventing thermal bridging compared to traditional aluminium frames. Low thermal conductivity materials, such as PVC, provide excellent thermal insulation and effectively reduce the risk of heat loss through windows.

With PVC warm-frame windows, we not only reduce the risk of thermal bridges, but also improve the energy efficiency of the entire window. As a result, we can enjoy better thermal comfort during the winter and reduce heating costs.

It is therefore worth considering windows with a plastic (PVC) frame as an effective solution for the winter months to prevent thermal bridges and heat loss.

8. Warm tape mounting

Warm tape installation is a window installation method that provides additional thermal insulation around windows. Special installation tapes are used to secure gaps and joints, eliminating thermal bridges in these areas. This is an effective solution to prevent heat loss and improve the energy efficiency of windows. At GM PLAST, we offer the option of warm tape installation, which is handled by specialists with 25 years of experience. More about this read here
