Save up to 30% for energy consumption in an industrial building!

What consumes the most energy in a building?

Heating, cooling, lighting and ventilation are the greatest energy consumers of a building. For this reason, insulation and airtightness are the two main factors which can reduce the costs. Studies have shown that, in order to build an energy efficient building on the long term, insulation is not the only option. Such an investment is highly unlikely to be worthy if the other issues are not dealt with.

Energy is lost in three main ways:
-Through panels (wall panels and mostly roof panels);
-Through thermal bridges and low insulation parts (windows, clerestory, etc);
-Through air infiltration through junctions.

Air infiltration issues:

-massive heat loss,



-deterioration of the building throughout time due to condensation inside the panels,

-on the long-term, water infiltration in the building.

If the difference between the outdoor and indoor temperatures is over 10 % and the air humidity is high, a 1-milimetre gap between panels causes infiltration of 360 g of water/day.
Meanwhile, mould comes out and the wall deteriorates. If the mounting is improper, the gaps can be larger. Yet, even correct mounting of the building can cause these problems.
For these reasons the building needs to be airtight.

Advantages of an airtight building:

-Reduces heat loss which results in saving up to 30% of the heating costs;

-Due to reduced heat loss, heating installation oversizing is unnecessary;

-The air in an airtight building is easier to manipulate. That is why, as contradictory as it may seem, an airtight building is easier to ventilate as low-capacity equipment is needed.

-Maintains indoor comfort:
• Indoor climate and air quality (less dust, pollen and insects)
• Construction process safety
• Ensuring the storage of goods and materials in good conditions
-Maintenance of the temperature through ventilation in an office building is lower costs if the building is airtight;

-Compliance with legal requirements (most EU countries have laws referring to building airtightness);
-Favourable environmental certificates issuing;
-Reduces CO2 emissions

How to build an airtight building?

In order to build an airtight building, the three components of the building and their joining must be taken into account.
• The floor being airtight, all joints are to be considered: panel joints, roof to wall joints, foundation to wall joints, the joints between the roof and the ridge and other flashings needed when mounting, joints for wall and roof accessories.

Airtightness is mainly achieved on the inside of the building to avoid heat loss while the external sheet metal covering is made airtight to ensure protection against natural phenomena, especially against water. It is important to achieve airtightness of the inside covering for multiple reasons:
- Condensation must be pushed outwards;
- Air vapours will not penetrate the panel insulation.
An airtight building starts with the project design and all airtightness solutions must be clear and achievable so that they can be easily applicable during construction.
