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.
