Frame houses are characterized by a tight structure, so they require proper air circulation. In order to enable effective air exchange, frame houses are increasingly equipped with mechanical ventilation systems with heat recovery (heat recovery systems). Mechanical ventilation provides access to fresh air in rooms, prevents the growth of fungi and protects against insects and dust entering the interior. The heat recovery unit also brings significant financial benefits. Frame construction and the use of heat recovery - everything you need to know on this subject can be found in the article below.

Frame construction and its thermal properties in the context of heat recovery
The growing popularity of frame houses is not only due to the speed and lower construction costs compared to brick houses, but also to their ecological and energy-saving nature. However, frame construction still raises many questions and doubts among potential investors. They concern in particular the thermal properties of frame houses.
Thermal requirements are becoming increasingly restrictive. To meet them, a frame house should have solutions that effectively reduce heat loss. Thermal insulation is of key importance. The energy efficiency of the building envelope depends on its quality. The lower the heat transfer coefficient (U), the better. Meeting thermal requirements is additionally facilitated by the (generally) very simple shape of a frame building.
As you might imagine, tight insulation does not help with access to fresh air, and constant ventilation is neither economical nor comfortable for household members, especially in the autumn-winter season. This problem is solved by heat recovery ! Heat recovery systems are advanced ventilation systems that not only exchange air, but also allow for the recovery of some heat from heated air. Household members constantly breathe fresh air (without regularly opening windows). Additionally, heat is recovered, which generates significant savings in the household budget. It is estimated that heat recovery can reduce heating costs by up to 40%! This is also a recommended option for allergy sufferers.
Can a frame house effectively accumulate heat?
The lightweight construction of a frame house does not facilitate the accumulation of heat, which causes its loss. Such a building heats up quickly, but also cools down easily. In order to prevent both excessive heating of the interior and accelerated loss of heat, it is worth taking care of a modern, automated heating installation. On the other hand, the recuperator will take care of the recovery of heat from the accumulated and heated air during air exchange. Thanks to this, the investor is able to save a lot on heating.
Efficient air exchange in frame structures thanks to heat recovery
Frame structures are generally energy-efficient, but can even be zero-energy. Tightness is their characteristic feature, resulting from the use of high-quality window and door joinery and the elimination of all sources of leaks. Although the tightness of the house means significant savings on heating, without taking care of effective air exchange it can negatively affect the health of the household, the comfort of life and the durability of the structure.
For this reason, more and more experts specializing in frame construction recommend installing an efficient heat recovery system in this type of buildings, which will ensure optimal air exchange.
Without heat recovery or constant ventilation, problems such as excessive moisture, a feeling of heavy air or cooking odours can quickly appear in a new frame house. Additionally, the heat recovery system will recover a large part of the heat, which will translate into significantly lower heating bills or heating costs. At the same time, the household will breathe filtered, safe air.
