In recent years we all noticed how important it is, to create a full air tightness strategy, which includes all parts of the building.
The more air tight we make a building, the more attention we have to put into small details, to prevent the enhanced risk of uncontrolled air infiltration through these areas.
Spots like chasings for conduits on exterior walls or junctions between floor and walls are becoming more and more important when it comes to a functional air tightness with values of 1.5 ACH (air changes per hour) or less.
But how can you make such areas steadily air tight? By using air tight membranes, tapes or plaster coating?
All three solutions above will create an air tight layer but in the most cases there is an easier alternative available:
Belgacoat Air Tight Paint
Advantages for the use of air tight paint:
We´re using and selling air tight paint since 2016.
It was originally developed for sealing the joints around windows, which does not work for the most buildings here in Ireland because of the cavity wall structure. But there are plenty of other options, where the air tight paint will beat any other air tightness strategy.
