A qualified air tightness test does not require more than 7-8 test report pages or an endless list of calibration certificates. A serious air tightness test takes approx. 2-3 hours for a dwelling and includes important details like the calculation of the building dimensions and a leakage detection. Also the quantity of performed air tightness tests is not an indicator for quality.

The main areas for air infiltration through the air tightness layer are penetrations through the layer. It is essential to have every single penetration sealed with an appropriate sealing strategy. We at prodomo Ireland would like to give you some inspiration about functional air tight sealing strategies.

Air tight paint is one of the greatest inventions for air tightness and we highly recommend the use, because painting is mostly easier and more efficient than taping. But unfortunately air tight paint is not suitable for external applications, where water tightness and UV resistance is the key. That´s the reason why Belgaplastics has been developed the new Belgacoat LR (Liquid Rubber).

Monolithic membranes are the better choice to wrap the building envelope of timber frame structures externally. Especially the popular (partly open) facade claddings require such a membrane with a long lasting UV resistance. Why should you select copmpetitors products with UV resistance levels of just a few months, when you can have the Belgawall B1 with a guaranteed UV resistance of 10 years and an outstanding B1 fire rating on top?

A common practice for air tightness here in Ireland is, to wrap the hollow core slab with air tight membrane. Attention is needed for some details, to achieve the best possible air tightness performance.

Not every air tight tape is suitable for window taping. Standard tapes, as seen on the left side of the photo do have disadvantages.

Multifoils like SuperQuilt are becoming more popular for insulation applications. Because of their high vapour resistance attention is needed, when installing such layers to standard roof structures, made of timber.

This detail can be found in many houses during the construction stage. I guess that in the most cases someone will put the window board or the kitchen work top on top and everything is covered. The occupier is wondering thereafter where the draughts around the window do come from.....

To achieve the best cell structure for our air tight & water tight foams, attention is needed to details like humidity and temperature.

From 01/01/2019 the revised Building Regulation for Connservation of Fuel and Energy (Part L) requires lower maximum values for the air permeability of new buildings and deep retrofits. We think it´s a first step into the right direction, but the mandatory values for air tightness are still too high, especially for common technologies like heat pumps and heat recovery ventilation. Our aim is and will remain max. 1.5 ACH (air changes per hour), wherever we´re involved in the air tightness.
