In the case of a passive house, additional work to be done is this overlay 1-2 millimeter sealing layer on the outer and inner surfaces of the walls, because this building is undergoing the pressure test needed for the passivity certificate.
When it comes to the scope of work, there is no problem, because in the implementation of the thermal insulation system, an adhesive mortar for mineral wool is used for this purpose. Instead of the traditional method of mounting on "cakes", we simply apply the adhesive mortar on the insulation material and stick it to the wall.
The traditional method of "pie" mounting in the case of a passive house is becoming a thing of the past. It is an innovation in Poland, while in countries with higher technology regimes, this is the normal method of attachment. An interesting fact is this, that with this method of fixing, the surface of the wall must be perfectly smooth. With any unevenness, this method cannot be used and only "cakes" are created.
System YTONG w 100 % provides us with a smooth surface of the walls.
From the inside, an internal thermal insulation system was used with a focus on improving the heat transfer coefficient and soundproofing the rooms.. The final finishing of the room is clinker brick. It allows you to create a heat accumulation chamber. Solar radiation energy falling on the glass in 50% it passes through it and falls on the floor or walls depending on the size of the glazing. If the solar radiation falls on a clinker brick or a partition wall made of SILKI, it is through heat accumulation that it improves the heat balance in the building.
YTONG technology is the correct technology for a passive house. Admittedly, passivity in Poland is such a "young" topic, that in the event of a discussion on this topic, There are more opinions than there are technologies available on the market and almost everyone discussing has their own concept of a passive house. The experimental building really needs 170 PLN per month for fees, and this goes to everyone, who pays more at the moment.
