Today, we expect window frames not only to protect against the elements, prevent break-ins, and effectively limit heat loss, but also to look attractive. Thanks to careful aesthetic design and the use of innovative solutions, modern windows meet these requirements and are an important part of the architecture of any building.

The durability of window frames is significantly influenced by the use of the best materials in their manufacture. The exceptional refinement of the windows offered by our company not only results in their sophisticated design and surprisingly low heat transfer coefficient; even the shape of the small locking elements, which are not visible from the outside, is no coincidence – their rounded edges make them easier to clean.

Current technologies are moving towards ecology and economy. The number of options for heating a single-family home is also increasing. Is it worth investing in an expensive system in the hope that it will soon pay for itself? Or is it better to save on the system and pay more for heating? Is it worth investing in ecological solutions?

Air-to-water heat pumps draw their thermal energy from the air. The temperature of the air varies throughout the year, but this does not affect the efficient operation of the pump. An air heat pump can also be operated at very low outdoor temperatures of up to -20 °C. This means that it continues to operate despite fluctuations in outdoor temperature and, depending on the residents’ needs, provides continuous heating for the house and hot water.

An air source heat pump meets the criteria for energy efficiency class A++. It also enables the building to be cooled – no additional equipment needs to be installed for this. This means that both cooling and heating of the building can be achieved with just one system, which increases the return on investment in an air-to-water heat pump.

All buildings undergo an airtightness test to determine how much air escapes from the building in an uncontrolled/harmful manner. Thanks to our experience and precise tools, we can also check all elements of the building in detail and find leaks that we can eliminate during the construction phase.

The airtightness of partition walls is crucial for the comfort, heating costs, and longevity of the building. In modern construction, the air permeability of buildings is being checked more and more frequently. This is very good, because leaky outer shells affect our health and well-being. Leaks in the building’s joints lead to higher heating costs in winter and higher cooling costs in summer. With the blower door test, we locate and seal all air leaks. The result is a modern, energy-efficient, comfortable building with a healthy microclimate. You receive a tightness certificate and an energy consumption guarantee for everything!

The airtightness test of your house allows you to locate air leaks, i.e., places where unwanted air enters or escapes from your building. In a blower door test, a fan covered with a windproof tarpaulin is inserted into the front door. This pumps air into the interior of the building or outside, creating positive or negative pressure, which is helpful in locating leaks with the aid of a thermal imaging camera or theatrical smoke.

During the airtightness test of the building, we determine the following parameters: q50 – air flow rate at 50 Pa [m³/h]. Total volume of air escaping from the building through the partition walls when the ventilation system is closed. n50 – air exchange rate at 50 Pa [1/h]. Total volume of escaping air (q50) divided by the net volume of the building. The lower the value, the better. Basic parameter for determining the airtightness of buildings. qe50 – air permeability at 50 Pa [m3/h*m2]. Comparison of the volume of escaping air with the total area of the building envelope. This parameter is used to evaluate the airtightness of very large buildings where the n50 parameter is no longer representative due to the favorable ratio of volume to area of the building envelope. qf50 – Uniform air permeability flow for 50 [m³/h*m²]. Comparison of the volume of escaping air with the floor area of the building. The airtightness measurements can be carried out for different pressure values, e.g., 10 Pa relative to the environment as a simulation of the operation of a so-called clean room, which is operated with a constant, slight overpressure.
