We all want to achieve the best values for air tightness for our homes. Good air tightness is not subjected to the brand of air tight products you use, but definitely how good and accurate they have been installed. It´s as always - the devil is in the detail. One of the most forgotten or bad treated detail regarding air tightness can be found in every socket. As far as I know, the conduits here in Ireland have to be used to protect the wires against aggressive substances coming out of the...

There´s no universal solution available for insulation upgrade and refurbishment. Many home owners have been selected insulated plasterboard sheets to improve the insulation of their existing houses, and even a certain amount of new buildings get the "insulated slabs" installed to the external walls. By doing an internal wall insulation, you should make a survey upfront, regarding the risk of interstitial condensation. The trouble of the most standard insulation products is the fact of cooling...

Penetrations of the vapour control layer need special attention regarding a permanent functional sealing. Some manufacturers are offering special grommets for the sealing of HRV ducts. Most of them are great but beside the cost factor, who stocks all the different sizes permanently? I did plenty of attempts how to seal the HRV ducts on an easy, affordable and save way. At the end, I found a solution by optimising the so called "flake bonding". By applying a total of 3 layers of air tight tape,...

It can be pretty devastating to see, how other trades dealing with already installed airtight membranes afterwards. No matter how bad it looks for the moment - all these additional and unexpected leakages need to get sealed properly again. Professional airtight installers will find solutions to bring messy installation back to a high airtight level.

I´ve been often asked about the certificates for airtight products. It seems most architects, engineers or builders have heard something about NSAI, BS, CE and other standards but not everybody knows exactly what it means. CE (coming from the French "Conformité Européenne" - which means European Conformity) is a conformity marking for various products within the most European Countries. Whenever a harmonised European exists for a product category, the manufacturer (or importer) has to state...

Many builders, airtight installers and self-builders are doing slight mistakes when it comes to airtight sealing of windows and doors. Sometimes they do not seal the bottom of the window frame, because it will covered by the window board afterwards. Sometimes they install the tape not as recommended by the manufacturer. But the most common mistake is the missing taping of extending window fixings like straps or joints between the lintels. It´s definitely not good enough to tape just the half...

The best airtightness installation is completely worthless in case of "improvements" and "changes" caused by other tradesmen afterwards. Based on our experience, we´ve collected so far at Irish construction sites, we would highly recommend the launch of two measures to ensure the best airtightness results during the complete construction stage and afterwards: 1. Training and sensitisation of other affected trades (e.g. plumbers, electricians, drywall installers) regarding how to deal properly...
